1. Introduction - The Construction Phase Health & Safety Plan

1.1 Objective of the Construction Phase Health & Safety Plan The Construction Phase Health & Safety Plan (CPHSP) is a document issued by the principal contractor Burmeister & Wain Scandinavian Contractor A/S (BWSC) to ensure that work related to the construction of the Snetterton Renewable Energy Plant Are Carried out in accordance with BWSC polices and legal requirements. The objective of the CPHSP is to describe rules that enable all parties to perform their work such that risks are reduced so far as is reasonably practicable. CPHSP has been developed from the information available to the Principal Contractor at the time of writing. The Pre-Construction Information document will be included in Appendix 01, when issued. The following assumptions have been, or will be made in producing this and future CPHSP:

• That the Purchasers Information and the Pre-construction Document adequately covers all relevant health and safety aspects identified at the time of its submittal and that all relevant information has been passed to the Principal Contractor.

• There are no subterranean services installations on the property, which can be a potential risk to safety and environment, when construction starts.

• There are contaminated ‘hotspots’ within the existing made ground, as outlined under item 5.5 herein.

The CPHSP will be continually reviewed and developed to reflect the changing circumstances as the project progresses through the construction phase. BWSC hereby confirms that in discharging the duties as Principal Contractor, adequate provisions have been made in order to comply with all relevant legislation and standards. BWSC will comply with the Approved Code of Practice (ACOP) for the Construction (Design and Management) Regulations 2007 (CDM regulations).




1.2 Health and Safety goals Everybody who works on this project is responsible for health, safety and the environment. This underlying philosophy is critical to the success of the project in terms of safety, quality, time and cost. BWSC East Anglia management recognises that people are the most important asset and as such will endeavour to safeguard their health, safety and welfare and that of others affected by the construction activities. Equally, all contractors working on the project must accept their responsibility to eradicate environmental impacts by controlling waste, reducing pollution, using energy efficiently and always striving to act considerately towards our neighbours, wherever possible. Our overall project goal is simply stated – to eliminate accidents and harm to people and the environment. As a minimum we must comply with legislation; strive for zero reportable incidents; and work together to ensure a safe site.

1.3 Current Update Revision 1 is issued – Construction works for the power station. Works updated in this issue:

• Civil Works • Erection of structural steel • Laying of underground utilities • Road works • Installation of ducts for 33 kV connection to Diss

2 Project Outline

2.1 General Description

The project comprises the turn-key delivery (engineering, procurement, construction, testing and commissioning) of the Snetterton Renewable Energy Plant (The project).

The project is designed on the basis of fuel in form of straw or straw in combination with other biomass fuels, typically wood chips, having the following main characteristics:

• Thermal input 130 MWth, Net power output 44,2 MWe • Fuel handling • Steam turbine and • Condensing and cooling




• Water treatment plant • Flue gas treatment • Boiler

The project will be located just to the west of the A11 at Snetterton, adjacent to the industrial area to the north west of the Beacon Hill junction. The center of the site is at Ordnance Survey (OS) national grid reference 600700 291100. The existing site location consists of farmed arable fields. There is no single topographical fall across the site. There is a well-defined system of ditches at the edge of the field system, draining to various tributaries which fall within the natural catchment of the river to the west. The project has the following main phases related to the site activities:

1. Enabling Works. 2. Construction works for the power station. 3. Erection works of the power station. 4. Testing and commissioning works.

He will continue to monitor the construction works and take initiatives where necessary to ensure that all required controls are in place. The Site Managers for the different disciplines are responsible for the on-site implementation, execution and monitoring of health and safety controls within their disciplines and as representatives for the Principal Contractor.




The Health & Safety Advisor is a Construction Health & Safety person with recognised and certified skills. He is based on site, where his role is to assist and support the Resident Project Manager and the site team, in discharging their H&S duties. Specifically, he will review H&S documentation and procedures, provide safety update services, conduct safety inspections and attend H&S meetings, attend to tasks related to the registration and coordination/approval of systems for RAMS, Temporary Works, Permit to Work, waste management, testing of electrical equipment and the like. The Health and Safety Advisor also has a reporting line directly to the BWSC QHSE Manager for use in case an extraordinary situation requires such communication. Contractors’ Site Management will discharge similar duties under their scope of responsibility. All contractors are to maintain a list of names for those employed or contracted and ensure that key safety information is communicated A detailed diagram showing the BWSC organizational structure is included in Appendix 05 and Appendix 06. The Site Safety Organization is shown in Appendix 07.

4. Construction Phasing and Key Methodology.

Broadly speaking, the construction programme is developed in 4 phases:

1. Enabling Works. 2. Construction works for the power station. 3. Erection works of the power station. 4. Testing and commissioning works.

While the list above indicates the natural sequence of events there is considerable overlap between the phases. From commencement of site works the total construction, erection and commissioning period is likely to be approximately 25 months.

Activity

4.1 Enabling Works The planning consent lists several activities that must be completed or finished to a specified degree before commencement of the actual development itself (i.e. construction of the Snetterton Plant itself).




The following activities are to be completed as part of the enabling works:

• Preparations for road widening works. • Widening of the existing road connecting the site with the A11, • Installation of a power supply to the site (by external Contractor), • Establishment of welfare and storage facilities and laydown areas, • Construction of the site access road, • Installation of perimeter fencing enclosing the site, • Installation of a site access control system, • Installation of a retaining wall in the North West corner of the permanent

site, • A remediation and monitoring plan for how to deal with the potential of

encountering contaminated soil is to be in place before site levelling (cut and fill) works can take place,

• Removal of topsoil and levelling the site, and • Excavation of areas under all major foundations in order to verify the

soil conditions and to remove any wet clay, debris and / or contaminated soil as may be necessary.

Above list of tasks are subject to change and may be adapted to fit the actual circumstances found on site. Light schedule:

• WC 16.02.15 Tree protection, site access road, incoming temporary

water supply pipe 1 week • WC 23.02.15 Make site storage, compound and parking area geotextile

and stone 2 weeks • WC 02.03.15 Road closure, highway works, incoming temporary

electricity supply 4 weeks

4.2 Civil and Building Works Following the completion of preparatory works, the actual site activities will commence with excavation for concrete works and underground utilities. The civil construction work will involve typical/standard construction practices, using traditional earth moving equipment, excavators, dozers and dump trucks for the site levelling and road works. Reinforcement works will be based on pre-bend iron delivered to site just in time. Only minor bending works will be performed on site. Formworks will be fabricated on site in an allocated marked area. Concreting of blinding layer and substructures (foundations, ground beams and slabs) will be based on ready mix supplied from off-site batching plants and delivered to site by mixer trucks.




Placing of concrete will be done either directly (via chutes), by concrete pumps or by crane. Traditional formwork and shuttering will be used for all structures, with the exception of some suspended slabs (in the straw barns), which will be supported on integrated formwork. Internal roads will be constructed using traditional road construction plant and machines. The roads are planned to be tarmacked with the 2 lower layers during phase 2. The last wear layer will be done at the last phase. Most of the underground utilities will be established prior to tarmacking the base layer of the roads. Scaffolding will be used for poring of concrete and for bricklayers.

4.3 Erection of Superstructures Fabrication of cast-in parts and steel structure for the superstructure is on-going at Caunton Engineering.

The steel structures are made as members to be fitted together with bolted connection. The erection is made by the use of mobile crane and hydraulic cherry pickers and using the slaps as laydown areas for the steel members. The steel members will arrive just in time and will not require other laydown areas than the slabs. Caunton Engineering will need a work area of 300 m2 close to the western straw barn.

4.4 Erection of Mechanical and Electrical Equipment. (phase 3)

Further description to be added as part of the update.

4.5 Testing and Commissioning (T&C) (phase 4) Further description to be added as part of the update.

5. Existing Environment

5.1 Previous and Current Use of the Site and Adjacent Sites

The existing site and adjacent areas consists of farmed arable fields. The construction site has been used as a soil extraction site.




5.2 Existing Structures No existing structures.

5.3 Existing Underground Services

• Drain pipe from Turkey farm relocated.

• 11 kV lines established.

• Underground utilities are being established.

5.4 Ground Conditions The construction site and adjacent farming land are registered as archaeological areas and only the construction site and the access road are cleared for excavation and construction. The other surrounding areas (the lot) and areas used in connection with the construction may be used for non-ground-breaking purposes.

5.5 Potential Contamination Sources

The summary of the ground investigation report states the following:

• There is no asbestos present at the site • There is no storage of hazardous materials at the site • There is no further contamination on site, than the mentioned

“Hotspots” in 5.5 in the main contract. • All necessary inspections and investigations are currently up-to date.

6. Construction Traffic and Access to the Site

6.1 Site Access The site access allows all vehicles to enter the site only bidirectional. Turn

round space will be ensured within the site so that vehicles do not reverse onto any existing roadway or route within the site or other. The internal driveways will be planned mainly for on directional traffic. There will be a physical barrier between the Staff Parking area and the Construction Site. No vehicles are allowed into the Construction Site without a permit. Contractors’ and visitors’ cars will not be allowed to enter the construction site without a permit and will have access to the designated parking area only. A speed limit of 5mph will be enforced on the site. All delivery drivers/visitors etc. are currently signing in at the security gate house and this will continue




throughout the construction phase and include all operatives and management personnel on site. Commercial vehicles e.g. vans and trucks will only be allowed to reverse if the driver is under the control of a banksman. All construction vehicles must have flashing or rotating beacons and reversing aids (combination of cameras and reversing siren) to be allowed admission to site. All vehicles are assessed prior to going on site. Site office and welfare facilities for the principal contractor and all contractors are located within the laydown/Storage/Office areas adjacent to the construction site. This is located north of the parking area. This area will also be used by various contractors for site offices and temporary site accommodation. Another laydown area will be located south west adjacent to the construction site. This is indicated on the site layout plan and traffic management plan (TMP) and will be reviewed periodically. The TMP issued as Appendix 3 will be implemented when main excavation works are finalized. Until then the TMP will be managed on whiteboard, as the management will change regularly with the excavations. The security gate house will be manned at all times, and the staff on duty will be prepared to assist in traffic management when required.

6.2 Deliveries

Most deliveries will take place within the normal site working hours between 0700 – 1900 hours on Mondays to Fridays and 0800 – 1400 hours on Saturdays. No deliveries take place on Sundays or bank holidays unless dictated by special circumstances and after obtaining the requisite permission, Deliveries or plant movements that are outside the normal permitted size or weight are notified to the authorities. These are identified in advance to allow the necessary liaison with concerned parties.

The majority of deliveries will be off-loaded within the lay-down area located to the North West of the site. BWSC will operate a `pre-booking system with regards to its contractor’s deliveries, in order to ensure the orderly and safe delivery of material and plant.

6.3 Traffic Volumes The construction team will reduce, as far as possible, any potential impact which construction works may have on the road network during the construction phase. This will be continuously monitored and checked to avoid disruption and nuisance to local businesses and residents.




Construction Material Deliveries The peak of deliveries will be during the earth movement and concreting

works phase.

Assuming an even distribution over a 9-month period (M5 to M13), where the major activities on excavations, foundation works and material and equipment deliveries are planned , the average will be 400 truck deliveries per month, or 20 trucks per day. This traffic volume is less than the volume during normal operation of the plant (This load will be calculated, when more accurate figures are available).

Deliveries of Fuel during Testing and Commissioning Further description to be added as part of the update. Expected Manpower Resource Levels Site labour levels will vary over the course of construction. Starting with about 20-30 persons in the first few months, it will gradually increase to a peak of around 350 persons around 22 months into the programme. The high manning level will last for about 4 months after which it will decrease to about 150 operatives.

7.0 Site Setup and Logistics

7.1 Accommodation and Welfare Facilities Site office facilities will be of good industry standard, based on portable units sourced from reputable suppliers. The units will either be at ground level only or double stacked, linked together with the main entrance at one end and a fire escape door at the other. Within this first phase 4 to 20 cabins will be placed within the construction area. The main office complex will provide facilities for the BWSC, a few selected contractors, the Client and the Engineer. This complex will include certain common facilities such as conference rooms, safety induction room and canteen facility. Toilet facilities are provided, but may be located in independent units. Steel ISO containers, tents and trailers are used for storing materials and tools. The relevant contractor’s supervisor is to be responsible for ensuring that all plant, equipment and hazardous material is securely locked away when not in use, or located within a fenced area. Skips for general waste and metals will be available throughout the construction stage. See further details under Section 8.7. The main site office set-up will remain in this location throughout the project.




Whilst some small subcontractors share the main contractor’s welfare facilities, other subcontractors shall provide their own facilities. The principal contractor shall ensure that the welfare facilities are complying with the requirements set out in the CDM Regulations, ACOP schedule 2.

7.2 Provision of Temporary Construction Services

Water for the works will initially, and if necessary thereafter, be supplied from bowsers. Later on in the construction phase, the intention is that a new temporary water main will supply the site with ‘town water’, which shall be distributed to various tap points on site. Electrical installations in connection with construction phase ‘power’ shall be provided in accordance with BS 7671 and BS 7675, and power supplied from the utility network, and on-site mobile diesel driven generators, until supply from local distribution company is established. Installations include distribution to strategically located power outlets. Electrical installations to temporary buildings and site power outlets shall be tested when first connected and a BS 7671 test/inspection certificate provided at least every 6 months. The tests shall be performed by a competent person with membership of a recognised electrical institution. Power for portable tools is derived from 110 V CTE transformers. Battery powered tools will be used extensively and charging points are only set-up in dry/safe areas of temporary or permanent buildings. Portable Appliance Testing (PAT) will be carried out by a qualified person every 6 months, or every 12 months in case of office equipment. Each appliance must display a suitable PAT test label. Contractors will maintain on site a current PAT register of equipment brought to site.

7.3 Protection of Third Parties All Site activities are to be contained within the hoarding line, and all necessary care will be taken to ensure that no disruption is caused to traffic on the public road or discomfort caused to neighbours. Specific loading and unloading areas will be designated inside the construction site boundary and at laydown areas. Initially the site will be guarded, outside of normal working hours, by a professional security company. From the start of the M&E construction phase, site security will be increased to provide 24/7 cover.




7.4 Sign Boards A project signboard will be erected according to the Client’s wishes and applicable local regulations. Signage at the main entrance includes all relevant health & safety signs complying with the standard ISO EN 7010.

7.5 Restricting Access to Authorised Persons, Site Security

The Site will be covered by 24-hour security guards, 7 days a week, contracted from a professional security company. During working hours, the security guard or other designated person shall be available at the gate(s) to control all access to and from the Site. Outside working hours, the security guards will patrol the Site at regular intervals. All access to and from the Site will be through the designated main gate and personal access gate. There will be no other entrance to Site. All persons who wish to enter the compound will be registered at the security gate house, either electronically or by signing in, before entering the site.

7.6 Perimeter Fence

The perimeter fence will be erected at the construction Site as a part of phase 01 The permanent perimeter fence will consist of quality intruder resistant wire mesh, not less than 2.8m high. Lockable gates will be provided at the entrance, and during day hours, access will be controlled by a barrier for vehicles and special access control for persons

7.7 Pedestrian Movements on Site

All footpaths and walkways within and along the perimeter of the site boundary will remain clear from construction activities. The footpaths will be clearly marked and segregated by suitable barriers. Where construction workers or others have to cross the internal roads, these crossings will be clearly marked.

7.8 Materials Control and Storage

Delivery vehicles will be controlled to ensure that unloading takes place in the correct location and to applicable H&S standards. “Just in Time” scheduling of deliveries, where possible, minimizes storage capacity needs, double handling and congestion around the site.

Where “just in time” deliveries are not possible, economic or practical, site storage of equipment and materials are controlled to designated locations.




Detailed plans will be maintained, outlining areas available for moving and storing materials during the various stages of the project.

Secure handling and storage of hazardous substances is controlled in accordance with the Health & Safety procedures. All contractors will be compliant with the statutory requirements and COSHH declarations will be filled in by all contractors on site and usage monitored and logged. This will also be reflected in the site emergency procedures. Laydown areas are foreseen along the NW area neighbouring the Site and on an adjacent area SE area neighbouring the Site.

7.9 Lifting, Cranes / Hoists

The majority of unloading and distribution will be done by telescopic forklifts. Unloading of some containers, as well as bulk cargo, will be done by mobile cranes under the control of a competent appointed person. All lifting operations must be pre-accepted through the RAMS system and a verified lifting plan put in place. All lifting equipment shall only be operated by a person holding the necessary licence to operate the equipment being used and the equipment is required to have a current valid inspection certificate. A lifting plan is required to be submitted for all significant lifts, and as such, is specific and valid for the operations for which it is intended only. All lifting operations shall take place under the supervision of competent appointed persons. Fork lift truck operations take account of good practice principles issued by the fork lift truck association: http://www.fork-truck.org.uk/fact-sheets

Lifting operations shall be planned and supervised. These activities shall be communicated to those affected, predominantly through the daily coordination meetings.

7.10 Construction Lighting Where work cannot be carried out properly and safely, under normal daylight conditions, suitable task lighting will be provided by the contractor responsible for the works in question.

The Principal Contractor shall ensure that adequate lighting is maintained to roads, car parking and pedestrian routes to work areas. If some work areas are found where sufficient task lighting has not been installed, in the interests of safety, and also to ensure that appropriate levels of workmanship are maintained, the Principal Contractor will provide this on a temporary basis, to the appropriate BS EN standard, and the cost implications

http://www.fork-truck.org.uk/fact-sheets




will be dealt with in accordance with the prevailing contract conditions. The same principle will apply to other types of works, installations etc. where shortcomings have been observed. Due to the location of the site, there are no nearby sensitive receptors. The construction lighting provided by BWSC shall be limited and task specific. Where temporary masts are erected for the construction works itself, the direction of the reflectors is pointed to the ground. Mobile light towers may be used, particularly during the winter towards the end of the day. These are small portable tower masts that contain a maximum of 4x1000 W reflectors, and with high quality of flat glass, which is directed downwards and into the site.

7.11 Language Difficulties All Managers/supervisors will be able to speak and understand English.

A number of operatives may not have a full working knowledge of English, or not be able to understand English at all. Hence, the following special arrangement will be made for these persons:

• All site rules will be verbally translated to personnel in their native

language unless they demonstrate a good reading ability in English (translator for this shall be provided by the company employing such persons).

• Their supervisor, or a representative from their engaging contractor, will act as an interpreter during site induction and similar.

• Induction and similar will be extended to include the meaning of safety signs and notices, including the F10 and First Aider details.

• Additional attention and monitoring will be undertaken by their engaging contractor, in order to ensure these workers are not disadvantaged in any way.

• Any health and safety instruction, including corrective action required, will be issued in the presence of their supervisor, to act as an interpreter and provide further explanation.

• Certain operations involving high risk, requiring direct communication between parties involved will only be permitted, if the persons involved speaks the same language, or safe and proper communication is ensured by other means, such as signalling (e.g. lifting operations requiring a signalman).

• Any and all language barriers will be crossed either through translation services or a translator being among the general workforce that can translate into the native language of the target audience.

• Any and all documentation received from non native English speaking sub-contractors and the like, must provide all documents in English for auditing and approval process and inform BWSC prior to submitting.




7.12 Personal Protective Equipment

Personal protective equipment (PPE) which is both suitable and appropriate to protect against the risks shall be provided free of charge to all operatives by the contractor responsible for the work operation. It should be noted, however, that although providing PPE is essential where relevant, this is done as a last resort and never as a substitute for a) changing the way things are done in order to ensure that the safest possible method is adopted, or b) introducing engineering controls if reasonably practicable

Instructions are given to employees as to how to wear and/or operate each item of PPE which they are required to use. Further, for special work where additional PPE is needed it is essential to provide an explanation to why this particular kit is needed and essential and what its limitations are. The instructions are provided by persons competent in the use of the PPE concerned. All operatives must wear the following as a minimum standard:

• Hard Hat. • Safety boots with steel toe-cap and midsole (pierce-resistant). • Glasses. • Hi-visibility clothing. • Gloves.

Supplementary PPE will be identified through the RAMS system and implemented accordingly.

8. Management of Activities with Risks to Health & Safety & Environment

8.1 Significant Hazards

The table below lists the significant main types of hazards envisaged during this phase of the construction. The controls described are indicative only and subject to specific analysis. These identified high risk activities will be communicated at meetings to those affected and the engaging contractor(s) are required to ensure that the information is passed on. PLEASE NOTE All elevated works will be risk assessed and not heights above 2 meters as specified in BWSC Health and Safety Manual.




Manual handling will be minimised by:

• Avoiding, so far reasonably practicable , that employees are carrying out manual handling likely to result in an injury

• Where that is not reasonable practicable, assess the risk to the employee

• Putting in place control measures to prevent such an injury occurring.

To ensure that workers’ hearing is protected from excessive noise at their place of work, BWSC will comply with the following:

• We will assess the risks to workers- health and provide them with relevant information at 80 db(A)

• Hearing protection will be provided at 85 db(A) • Workers will not be exposed to noise levels exceeding 87 db(A)

To prevent health issues caused by vibration BWSC will comply with the following:

• Assess the risk to the health of our workers from vibration, and effectively plan for its control.




• Property manage the risks • Provide suitable work equipment for our workers, having regard for

technical developments in tool design and vibration suppression. • Maintain equipment fully and correctly • Give our workers and supervisor’s information and training on the risks

to health caused by vibration, and the safe use of the work equipment that is provided.

• Provide health surveillance/health monitoring where risks cannot be completely eliminated.

• Report any confirmed cases of HAVS or VWF to Health and Safety Executive (HSE).

• Consult our workers and their appointed representatives on proposals for dealing with vibration.

8.2 Safe system of work In general, all construction works are subject to the rules, regulations and guidelines in force in the UK or referred to in the BWSC Health & Safety Manual, included in this document as Appendix 12, whichever is most stringent. The following highlights some key principles:

• Each of the main elements of construction work shown on the project program will be described in the form of works packages, and Risk Assessed Method Statements (RAMS) are developed from these. Lifting plans are included in these where lifting operations take place.

• Generic documents may be used where these have been endorsed and found adequately suitable for the actual project conditions on the construction site.

• All RAMS must be reviewed and accepted by BWSC before any work commences on site.

• All temporary works are subject to design and review by competent appointed persons, and their status shall be maintained by the Principle Contractor in the Temporary Works Register.

• Contractors are required to submit the aforementioned documents as early as possible and no later than 10 days before the programmed start of the work under consideration.

• The RAMS shall be fully explained to the operatives undertaking the work. Copies of all RAMS are kept on file and made available to all operatives involved in the work.

• The RAMS are to be read and signed by all operatives involved in the work, ensuring they have understood the contents and will work towards the safe systems documented.

• Work where anyone is subject to the risk of a fall is to be carried out by selecting the most suitable equipment for example using scaffolding or Mobile Elevated Work Platforms (MEWP).




• Scaffolding is subject to inspection by a competent person prior to its use, and thereafter on a weekly basis. Records of inspections are maintained in the scaffold inspection log. “Scaff-Tags” are displayed on the scaffold.

• Loading platforms are to be incorporated into the scaffolding where required.

• The use of ladders is subject to guidelines provided in the H&S Manual or specific Method Statement.

• All excavations shall be supported/shored as appropriate, or the sides battered if deemed necessary by a qualified civil or structural engineer.

• A written Permit to excavate procedure is enforced on site. • On-going records of buried services are maintained. The contractor

who installs the service in the ground is to accurately plot and note details of the same before it is covered. The records shall be submitted to the Resident Project Manager for inclusion in the consolidated records sheet.

• Safe lifting methods shall be implemented by all contractors. • Permanent access and fall protection, e.g. stairways and

handrails/edge protection shall be erected as soon as practicable. • Nets, restraint- and fall-arrest equipment will be used and maintained

according to manufacturer’s instructions. When using the systems adequate emergency arrangements will be in place to allow safe rescue.

• The need for the documents as outlined above will be continually assessed as the project progresses. The formal vehicle for such assessments is the Health & Safety meetings and other relevant channels. The H&S meetings are generally held on a monthly basis; however, this is supplemented by the weekly meetings held with individual contractors.

8.3 Noise & Vibration

Sources During the construction of the project, the main sources of noise and vibration are from the construction plant and equipment such as:

• Construction plant: hydraulic breakers, crushers, excavators, dozers, backhoes, dump trucks, rollers, plate vibrators, compactors, etc.

• Mobile cranes • Generators (gen-sets used for construction site power) • Air compressors. • Pumps for de-watering • Concrete delivery mixer trucks • Concrete pumps • Movable Elevated Work Platforms (“cherry pickers”, scissor lifts). • Power tools, such as concrete vibrators, angle grinders, jack hammers,

diamond core drilling machines.




The risks and controls shall be communicated to those affected.

Safeguards In seeking to reduce the noise disruption from the construction activities, relevant safeguards will be consulted, specifically:

• The guidance set out in BS 5228: Part 1:1997 that covers noise control on construction sites

• The Best Practicable Means defined in the Control of Pollution Act 1974 section 72.

In general, the following measures will be considered:

• To the extent practicable utilize construction techniques that minimize the generation of noise.

• Use of acoustic hoarding where necessary • Use well maintained (according to manufacturer’s guidelines) silenced

plant • Ensuring all diesel driven plant has proper and effective sound

reduction measures (mufflers, baffles or silencers) and that these are well maintained.

• No plant shall be left running when not in use. • Ancillary pneumatic equipment will be fitted with mufflers or silencers • Utilisation, where possible, of pre-fabricated components. • Provide all operatives with CE marked ear protection of good standard

and ensure it is correctly used.

8.4 Dust, Mud and Emission Management

The generation of dust from construction activities is closely monitored and appropriate mitigation measures taken to minimize the impact on people on site as well as the local environment.

As no on-site mixing of concrete takes place, there is no dust or other nuisances created by storage and handling of cement or batching operations. Cleaning of the site access road is carried out daily or when required. It is important to recognize that this will need to be monitored consistently throughout the day in with due respect to the actual weather conditions and site operations taking place. Additionally, the following control measures will be implemented:

• Lorries bringing potentially dusty materials to or from the site are covered to prevent material being blown to the road during transport

• While on site, banksmen are required to clear large debris immediately.




• Sweepers are employed to clean the roads where appropriate • Speed limits are in place and enforced on the site (10mph) • Locating stockpiles out of the wind where possible • Keeping stockpiles to a minimum practicable height and use gentle

slopes • During prolonged periods of dry weather, measures are taken to keep

any stockpiled material in a damp condition by water spraying. • Damping down using water bowsers and sprays when conditions

dictate. • Effective wheel washing facilities will be provided and used for vehicles

leaving the site as necessary. • Prohibiting any fires on site. • Ensure exhaust from diesel driven plant does not discharge directly at

the ground or into a work place. • Ensuring all polystyrene and similar lightweight materials are weighed

down. • Make sure all dust generating materials are properly packaged.

8.5 Vehicle Emissions All construction vehicles are required to comply with relevant European standards. Suppliers and drivers are required to:

• Switch off their vehicle’s engine when stationary to minimize exhaust emissions

• Maintain engines in good tune and catalysts working properly The Principal Contractor will manage contractors in order to ensure they comply with all regulations.

8.6 Special Precautions for Material Used Handling of Substances

• Control of Substances Hazardous to Health (COSHH) assessments will

be undertaken by all contractors for all hazardous substances under their control, e.g. dust from drilling masonry, use of solvents, welding fumes etc.

• Paint, chemicals and other hazardous substances shall be adequately stored, labelled and handled

• Material Safety Data Sheets (MSDS) for all chemicals will be held on site by each contractor and shall be consulted when performing.

• A high standard of personal hygiene will be maintained by persons involved in potable water and waste/sewer work.




8.7 Waste Management

The overall objective of the Waste Management is to ensure that materials on site are managed efficiently and all waste must be disposed of legally. Waste material shall be sent for recycling, reuse and/or recovery to the maximum extent possible. The Waste Management will follow the Duty of Care requirements for controlled waste (Waste management, the Duty of Care ACOP 1996). The removal of waste products from site will be minimised by reusing excess materials wherever possible. Surplus soil and other waste will only be deposited in designated areas or licensed landfills, if necessary.

The types of waste identified during the construction phase include the following:

Control Measures

• Hazardous waste is segregated from other waste streams and stored

according to COSHH assessments. • Segregation of other waste types to facilitate recycling • Skips are located away from sensitive areas (water courses) • All waste containers and skips are clearly labelled with their content • Waste will be prevented from escape by using covered skips where

necessary • The site will be subject to regular and thorough house keeping




Monitoring Monitoring of the implementation of control measures is part of the daily site walk inspection carried out by the Health and Safety Advisor, assistant Site Manager as well as the Site Supervisors. Additionally, weekly HSE inspections are carried out by the site team and by external H&S Manager and advisors. Monitoring will be proactive and reactive and not all proactive monitoring arrangement may be documented. The records (e.g. Controlled Waste Transfer Notes) are kept according to regulations. BWSC will have a detailed site waste management plan in place. The system records every single movement of waste throughout the site during the entire course of the project. It also records what has been re-used / recycled. All waste carrier numbers are cross referenced with the Environmental Agency database to ensure they are legitimate and the licence is still current and valid. All contractors are to be aware of the BWSC Environmental policy/policies and adhere to this standard as a minimum requirement on site.

8.8 Fire / Emergency

The Fire Emergency Plan and the Fire Risk Assessment will be issued as appendix 10 in the CPHSP phase 2. During the enabling works the Muster Point will be at the BWSC office container. Fire Extinguishers will be located the following places:

• Office containers: CO2 and multi powder extinguishers • Closed Entrepreneur Equipment: CO2 extinguishers

In case of fire, all registered personnel must go to the muster point. The Resident Site Manager will contact the fire department and take charge of the fire management until the fire authorities are at site. It the Resident Site Manager is not on site, his responsibilities will be handed over to a capable person.

8.8 Controlling environmental effect on adjacent land There are no noise level requirements at boundaries specified in the Planning conditions.




There are no vibration level requirements at boundaries specified in the Planning conditions.

BWSC, will regularly monitor dust during according to the requirements from the environmental permit.

9. Continuing Liaison and Control

No assumptions have been made by the Client as this will be for the Principal Contractor to

determine. Commonplace hazards that should be known and appropriately managed by a

competent contractor through good site management practices implemented by the Principal

Contractor.

4.2 COORDINATION OF ONGOING DESIGN CHANGES

The Principal Contractor will comply with the design review process in accordance with

Contract Agreement Clause 5 Design and Annex 1 Part 13 Documentation and if requested

shall attend meetings called by the Employer’s Representative to ensure any design changes

are recorded and communicated effectively.

4.3 DESIGN RISK ASSESSMENT

Each designated “Designer” on the project must produce a risk assessment approach for their

design in accordance with CDM 2007. These will be collated as a risk register and submitted

into the design review process. The CDM Co-ordinator must be issued with copies of all design

risk assessments and designer risk registers throughout the duration of the Works.

The Designers are responsible for removing potential hazards during the design stage and

where this is not possible they must identify suitable “Control Measures” required to remove

or reduce the risk of these hazards occurring. Any Residual Risks/Hazards present upon

completion must be identified for inclusion in the Health & Safety File for future reference.

4.4 HAZARDOUS MATERIALS

No significantly hazardous materials have been identified during the design works at this

stage.



5 THE HEALTH & SAFETY FILE

5.1 CONTENTS OF THE H&S FILE

The assembly of the Health and Safety File will be coordinated by the CDM Co-ordinator

following completion of the project. The actual content of the file however will be provided by

the contractors working on the project, and compiled by the Principal Contractor under the

guidance and coordination of the CDM Coordinator. The suggested content of the Health and

Safety File according to CDM 2007 is as follows, but a more detailed contents requirement is

provided in the Contract Agreement Annex 1 Part 1 section 7.7.2:

(1) A brief description of the Works carried out;

(2) Any residual hazards which remain and how they have been dealt with (for example,

surveys or other information concerning asbestos, contaminated land, water bearing

strata, buried services, etc.);

(3) Key structural principles (for example, bracing, sources of substantial stored energy –

including pre- or post-tensioned members) and safe working loads for floors and roofs,

particularly where these may preclude placing scaffolding or heavy machinery there;

(4) Hazardous materials used (for example, lead paint, pesticides, special coatings which

should not be burnt off, etc.);

(5) Information regarding the removal or dismantling of installed plant and equipment (for

example any special arrangements for lifting, order or special instructions for

dismantling, etc.);

(6) Health and Safety information about equipment provided for cleaning or maintenance

of the structure;

(7) The nature, location and markings of significant services, including underground cables,

gas supply, fire fighting services, etc; and

(8) Information and as-built drawings of the structure, its plant and equipment (for

example, the means of safe access to and from service voids, fire doors and

compartmentalisation, etc.).

In addition, the Client expects Operations and Maintenance manuals for all the installed plant

Health and Safety Manual – part 1 – General safety program Responsible: HAJJ Approved by: JPE

Subject: BWSC Quality, occupational health, safety and environment policy

1 The Health and Safety Manual

The purpose of the BWSC safety program is to describe BWSCs requirements to a safe system

of work. By implementing this program work will be planned and carried out in a controlled

manner thereby preventing harm to people and to the environment.

The safety program shall be implemented from mobilisation of the site and remain in force

until demobilisation.

1.1 Scope of manual

The BWSC Health and Safety Program applies to all personnel on BWSC construction sites

including BWSC own employees, contractors and their sub-contractors, visitors and client

representatives.

1.2 How to use the Health and Safety Manual

The health and Safety Manual is divided into two parts and further supplemented with

appendices.

Part 1: General Safety Program

Part 2: Specific Safety Instructions for selected disciplines

Appendices: Standard forms and check lists (only with the electronic version to site

management)

Part 1 states the overall policies and principles guiding the BWSC Health and Safety work.

A chapter is devoted to each of the Health and Safety initiatives which will be implemented

at the construction site. The corresponding guidelines are also included here and

referenced to necessary forms and checklists where possible.

Part 2 provides specific and more detailed instructions for the various activities and areas

of work. This part 2 is divided into Common Activities, which are relevant for all technical

disciplines and separate chapters for Civil Works, Electrical Construction, Mechanical

Construction and Test & Commissioning activities.

Please note, that some activities, which are most commonly found in one technical field

may also be applicable in another. For example, the subject of ‘Work inside large

machinery’ will apply to work in for instance diesel engines and generators by both

mechanical, electrical and test technicians. Likewise is ‘hot work’ included under

mechanical work, although welding and soldering may be done by other disciplines also.

All staff with supervisory responsibilities shall familiarize themselves with this manual.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


7

1.2.1 Access to the Health and Safety Manual

The H&S Manual is available in a printed as well as an electronic version. The electronic version

can be obtained on CD ROM media or accessed via BWSC’s Intranet portal. In the electronic

version all standard forms are included in original file formats (Word, Excel) to be used and

modified for specific projects.

1.2.2 Hierarchy of manuals

In addition to this manual health and safety work may be governed by rules and regulation or

other safety instructions, typically those issued by the client and already in force at the work

site.

In order to avoid conflict between safety rules the following hierarchy shall be used as a

guideline:

1) Local legislation, regulations and other national requirements shall be followed. Please

note that in some countries guidelines (in the UK known as Approved Codes of Practice

– ACoP) have a legal status and should be followed unless an alternative safe system of

work is deemed to provide the same or better results.

2) Client health and safety requirements will normally take precedence over BWSCs Health

and Safety Manual.

3) BWSC Health and Safety Manual will take precedence over contractors’ health and

safety manuals unless otherwise decided.

4) Contractors’ health and safety requirements will be applicable for the activities

performed by that contractor. In case of conflict with any of the above requirements

the more onerous will take precedence unless otherwise decided.

5) Sites may need to produce a list of site specific procedures or site specific decisions as

a consequence of work development or on the basis of review of procedures from the

contractors.

Normally this list of site specific procedures will form part of or be referenced in the Site

Health and Safety Plan (in the UK: Construction Phase Plan).

3 Safety Organisation

3.1 BWSC Safety Organisation

The BWSC Construction Manager has the overall

responsibility in safety matters related to work on

BWSC construction sites.

The BWSC Site Manager has the overall responsibility for the safety on site.

He is directly involved in managing and coordinating the health and safety activities on site

ensuring that a safe system of work is in place. He will monitor the construction works and

take initiatives to ensure all required controls are in place. He reports to the BWSC

Construction Manager.

The Site Manager also has the role of Site Safety Officer; he may be supported by a Health

and Safety Officer and a Health and Safety Advisor if appropriate.

The Site Safety Officer or his appointed deputy will be on site at all times when work is being

carried out

The safety organisation shall be constituted as soon as the site is mobilized. The parties

representing the Client and BWSC are appointed as early as possible, while the rest of the

organisation, representing contractors and others, shall be assigned as and when they appear

on the site.

The safety organisation, including a list of names shall be kept updated and posted on the

bulletin board.

3.2 The Safety Board

Safety coordination between BWSC and contractors on site will be organised through a Safety

Board consisting of the Site Manager, BWSC supervisors and the contractors’ site

management. Each subcontractor will ensure consultation with his workforce in accordance

with regulations.

The Safety Board will meet every second week as a

minimum. These meetings can be a part of normal

site meetings. Minutes of meeting shall be taken

and corrective and preventative action shall be

decided and followed up.

3.3 Responsibilities

3.3.1 Site Manager (Site Safety Officer)

It is the main responsibility of the Site Manager that the health and safety program is

implemented on site. Through actions and communication he shall ensure that safety

awareness is part of the work culture on site and that safety priorities are always given due

consideration in the planning and execution of the works. Specifically, the following duties can

be highlighted:

Understand the health and safety policy and the responsibility that follows.

4 General Safety Requirements

4.1 Construction, commissioning and semi-operation phases

BWSC’s Contracting Division is a turnkey supplier of power plants. It is important to be aware

that safety aspects are changing from the construction period to the commissioning period and

onwards into semi-operation stage. It may be the case that operational responsibility for one

or more units is taken over by the end-user, while construction and commissioning activities

are still ongoing in the remaining plant. This period is called ‘semi-operation’ period.

Consequently, it is essential to follow all safety regulations during construction, commissioning

and semi operation as well.

4.2 Transfer from construction to commissioning When the test & commissioning of the plant commence, construction work will still be on-going

in other parts of the plant. Gradually, after finishing the pre-tests, the various systems will be

energised/pressurised (the power station gradually becomes live). In this period when the site

slowly and gradually changes from a construction site to a test and operation site, particular

attention shall be given to safety aspects from the site management as well as from everybody

working on the site. Especially the construction personnel shall keep very alert in this period,

as their working place and the equipment that they have been working on for a long period

with free access now becomes “LIVE” with an increased potential danger, and consequential

limitation of access.

4.3 Transfer from commissioning to operations When commissioning is completed the responsibility for the operation is transferred to the final

operator and no work shall be carried out without the permission and knowledge of the

operator.

It is the responsibility of the Commissioning Manager in co-operation with the Site Manager to

keep all personnel working on the site well informed about which parts of the plant have been

taken over by the final operator.

4.4 Alcoholic beverage and drugs

Alcoholic beverages, cannabis or any kind of narcotic drugs are prohibited on the site.

Any person found to be under influence of alcohol, cannabis or narcotics are subject to

immediate dismissal from the site.

Personnel who need to use medicine which can influence their physical or mental ability to

safely perform their work duties shall report this to their superior such that a risk assessment

can be performed. Based on this risk assessment a decision will then be made as to whether

the person need to take time off or if it is acceptable to perform restricted work until the use of

the medication stops.

4.5 Language difficulties

BWSC construction sites are often a multi-cultural, multi-language environment. While all

BWSC supervisors have a good working knowledge of English, the same may not be the case

for contractors and operatives on the site. In cases where English is not widely spoken, it may

be necessary that safety related issues are communicated in other languages. The same will

be the case if foreign, non-English speaking nationals are employed on site, either by BWSC or

contractors. As a minimum, it shall be ensured that the Site Rules and any safety instructions,

signage etc. are translated to the relevant language(s). Likewise, the Site Safety Induction

shall be given in the relevant language(s), if necessary with the assistance of an interpreter.

5 Site Layout

5.1 Purpose and contents

The construction site layout is an important tool throughout the project for the coordination

and communication of safety related matters.

At the outset of the project BWSC design office will issue a layout drawing indicating known

installations and utilities as well as new structures and installations. This drawing will form the

basis for the Site Safety Layout drawing, which will be updated and re-issued by the Site

Manager as the project progresses.

The following list contains information which will be relevant to include on the site Safety

Layout:

5.1.2 Existing installations and site conditions

Overall demarcation of the site boundaries, indicating where BWSC is responsible for safety

and security. This may include areas which are not physically part of the main site, such as

off-site lay-down or work areas.

Existing services, underground and above ground (electrical, telecommunication, fuel, gas,

water, sewage etc.).

Existing building structures and installations, whether planned for demolition or to be

retained.

Areas with known or potential contaminated soil.

5.1.3 BWSC temporary site installations

Main access gate and security guard location, if any.

Site offices.

Welfare facilities (mess, sanitary facilities).

Emergency Assembly Point(s) and evacuation routes.

Location of Main First Aid Station/Infirmary, distributed First Aid Equipment, Fire Fighting

Equipment.

Storage containers, lay-down areas.

Refuse and waste handling areas.

Temporary utilities installation.

5.1.4 Traffic plan information

Site access, entrance and exit.

Car parking and turning areas.

Roads with indication of driving directions.

Pedestrian walkways.

Location of tower cranes indicating work radius and similar information.

Depending on the phase of the project, it may be relevant to include working areas showing

major excavations, large cranes, subassemblies, mechanical workshops etc.

When preparing the site layout, please keep in mind that too much information in a drawing

can lead to confusion. Therefore, the usefulness of the information provided shall be weighed

against the desired level of detail.

6 Safety Induction and Site Rules

6.1 Site safety induction All personnel working at or visiting the construction site shall be given a Site Safety Induction

before commencing any work / visiting activities. The Site Safety Induction is based on the

General Site Rules, which are handed out and explained.

During the induction session, special emphasis shall be given to significant risks which are

relevant to the current construction phase.

The Site Safety Officer is responsible that all personnel are given the Site Safety Induction. He

may delegate the task to BWSC supervisors, or in the case of major contractors, to the site

management of such contractor. Records of all site inductions shall be kept by BWSC Site

Safety Officer.

Attendees at site inductions are required to confirm by

signature that they have attended the induction. The signature

sheet shall contain the correct revision number of the General

Site Rules applicable.

Personnel having completed the Site Safety Induction are given a

name / ID card to confirm that the site induction has been

attended.

ID card format is included in appendix.

6.2 General Site Rules

A set of ‘General Site Rules’ is provided in the Appendix. They are based on experiences from

BWSC sites and updated as new knowledge becomes available. The General Site Rules may be

amended by each site to suit the site conditions and the phase of the works.

The site rules however cannot remove or lessen requirements stated in the Health and Safety

Manual unless a formal deviation is approved.

each project.

1 Do it safely – or not at all

2 There is always time to do it right

3 Always comply with legislation and regulations

4 Always comply with BWSC internal procedures and requirements for QHSE

5 Always plan and execute work carefully to minimize risk to people and to the

environment

6 Always ensure that a safe system of work is in place and is followed

7 Always stop work when at-risk behaviour or risky conditions are observed

8 Always ensure that personnel are competent and suitably trained for their work

9 All personnel shall be given a site induction before commencement of work

10 All incidents including near-miss shall be reported

11 Smoking is only allowed in designated areas

12 Familiarise yourself with emergency and evacuation procedures

13 Alcohol and drugs are not allowed on site

14 All personnel shall wear the appropriate PPE

15 Be aware that risks are constantly changing as the site is developing

6.3 Health Information

BWSC cannot require employees to disclose details of their physical or mental condition unless

the employee in question agrees to do so voluntarily.

Personnel using prescription medicine shall inform the Site Manager such that contingency

measures can be taken.

Should certain items of work require particular physical abilities these must be evaluated

individually and only with the explicit consent of the employee and in accordance with the laws

of the country.

7 Safety Meetings

7.1 BWSC Safety Meetings

BWSC convenes safety meetings on a regular basis with the contractors engaged on the site.

The meetings are held as a safety meeting (Safety Board) involving all contractors working on

site at any given time. These meetings are supplementary to the meetings held individually

with each contractor (weekly site progress meetings).

Safety Meeting Agenda (typical)

1. Minutes of last meeting; comments and acceptance.

2. Review of safety incidents since latest meeting.

3. Outline of planned work and related health and safety

requirements:

One month look-ahead co-ordination of work and

outstanding risk assessments and method statements.

4. Training including toolbox talks.

Induction training provided, toolbox talks provided,

training needs identified

5. Initiatives and improvements.

Based on site inspections and review of outstanding

identified matters.

6. Special requirements including resources for future

work.

7. AOB

The Site Safety Officer chairs the safety meetings.

21

7.2 Toolbox talks

Toolbox talks are short informal gatherings,

often at the workplace around the toolbox,

hence the name "Toolbox talks”. They can

also be performed in a meeting room but

still be presented in an informal way.

A toolbox talk is focused on one specific topic and shall be addressed in simple terms. It is the

opportunity for a supervisor to emphasize the importance of a particular issue or procedure,

and for the rank-and-file to ask questions or make serious comments. Normally, toolbox talks

should be held on a weekly or bi-weekly basis, or when specific circumstances arise. They

generally last no longer than 5 to 10 minutes.

For getting a clear structure in your toolbox talks, consider the following 5 points:

1. Toolbox Talks should be presented - not read.

This type of training takes its name from the notion of supervisors and employees

gathering around the toolbox informally to talk about an important issue. This means

the presenter should review topic materials before the meeting, and then present the

topic.

2. Toolbox Talks should be presented by a supervisor, foreman or similar type of person

with hands-on experience.

Do not delegate this important task. Toolbox talks presented by a credible supervisor

are far more likely to be taken seriously.

3. Toolbox talks should address the hazards at your workplace.

Present toolbox talks that are relevant to the type of work being performed at the given

time. Otherwise, you will quickly loose the attention of your workers.

4. Toolbox Talks should be quick and to the point.

You can likely address one specific hazard or issue and the relevant safe-guards in a 5-

10 minute time span. You want your audience to absorb and remember this safety

training and you will have more success if you keep the talk short and to the point

5. Toolbox Talks shall be documented.

Keep records of the toolbox talks. Each participant shall sign his attendance at the

toolbox talk.

For inspiration on toolbox talks see for example www.toolboxtopics.com

7.3 Other safety meetings

Depending on the situation, the client or his representative may convene regular safety

meetings. Frequency, agenda and other formalities will follow the client’s requirements.

8 Site Safety Inspections

8.1 Daily safety monitoring

Daily “walk-around” informal monitoring of the site safety is the responsibility of anyone

having a supervisory role and shall be a natural part of his daily presence on site.

The Site Manager will on his daily site walks monitor the safety and discuss any observed

issues with the responsible supervisor or contractor.

Breach of safety regulations shall be corrected immediately.

8.2 Formalised safety inspection

Formal and documented safety inspections shall be carried out by the Site Manager at regular

intervals, normally on a weekly basis or more often. Joint inspections with participation by

BWSC, the client’s representative and the safety officer(s) from contractors may also be

performed.

The overall purpose of the safety inspections is to review the implementation of safe working

practices. The inspections and subsequent reporting may be structured around the following

topics:

Housekeeping

Use of personal protection equipment (PPE)

Plant and equipment

Electrical installations (construction site power)

Work at heights

Lifting operations

Excavations

Work with power tools and special tools

Hot work

Fire hazards, fire-fighting equipment, alarm system

Use of chemicals and hazardous substances

Work inside large machinery

Work in confined spaces

Safety signage and posters

Emergency equipment

Safety records (induction records, equipment checklists)

Temporary works

Contractors’ health and safety control (management of health and safety)

23

Additionally BWSC and contractors will perform formal health and safety audits in accordance

with their audit programs.

8.3 Work in shifts If work is being performed in evening or night shifts, it may be relevant to carry out the safety

inspections at different times, as conditions may differ on these shifts.

8.4 Reporting from safety inspections The observations made

during the Safety

Inspection shall be

recorded and a report

issued to concerned

parties. The report may

also include

recommendations to

improve the observed

practices. A practical way

of doing this is to take a

series of photos, which can

then be included in the

written report.

Subject: Incident Reporting

9 Incident Reporting

9.1 Reporting of incidents (injury, illness, dangerous occurrence)

9.1.1 Principles

In BWSC we believe that all incidents are preventable. We also believe that good planning and

careful preparation is essential to prevent incidents. Despite good planning and preparation

incidents may occur.

Incidents are unplanned and undesired events which may or may not cause loss or damage.

Incidents represent opportunities for improvement if they are properly reported and their

causes are determined. Action shall be taken to prevent future similar situations by

instigating preventative measures.

The Site Safety Officer is responsible for reporting of incidents. A standard report form is

included in the appendix. A detailed risk management procedure is included in the BWSC

QHSE Management System.

Incidents are divided in two groups:

Injuries and

Dangerous Occurrences.

The following definitions apply:

9.1.2 Injuries

An injury is an unplanned event that results in injury to personnel. It is commonly agreed that

injuries are sudden occurrences while illness normally develop over a longer period of time.

Illness which is a consequence of work impact shall be reported as ‘injuries’.

9.1.3 Dangerous occurrences

A Dangerous Occurrence in an unplanned or undesired situation. The Dangerous Occurrence

may or may not result in loss or damage such as lost production, damaged equipment,

pollution etc. A Dangerous Occurrence which did not incur any loss or harm is often referred

to as a ‘near-miss’ situation.

9.1.4 Potential severity

The actual severity of an incident is the result or consequence of the incident. By determining

the potential severity of an incident we evaluate what the consequences of an incident under

slightly changed circumstances might have been. The severity of an incident – actual and

potential - should be determined using the risk matrix – see section 9.6. The potential

severity represents the likely risk of an unplanned or undesired situation and will determine

the degree of follow-up. Higher risk requires more stringent follow-up.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


25

It is important that situations

which caused injury to

personnel or damage to the

environment are always

reported.

Similarly does BWSC require

that all incidents which

caused loss or damage to

machinery, installations or

other assets are reported.

Dangerous occurrences which

did not result in physical loss

or damage should also be

reported as they may be

used to prevent similar

situations in the future.

These situations are often

called near-miss situations

and represent a valuable

source of information.

Dropped objects - objects

which are lost or fall from

height - may have severe

consequences if persons are

hit. Energy above 40 Joule

will most likely result in a

person being killed by the

dropped object. Dropped

objects therefore have a

separate field in the Incident

Report form.

9.2 Distribution of incident reports Incident reports shall be distributed as follows:

Original signed form to Site Safety File

Electronic copies to BWSC head office (Construction Manager, Project Manager, QHSE

Manager)

Electronic copy to the Client and/or the Resident Engineer

Electronic copy to the engaging contractor

Electronic copy to the responsible and/or relevant BWSC supervisors.

authorities.

The site manager ensures that legal requirements are adhered to.

9.4 Incident statistics /Lost Time Injury Frequency Incident Reports are input to the BWSC database for incidents.

In line with international standards BWSC use the following formula for calculating the risk of

injuries to personnel:

Lost Time Injury Frequency = number of injuries calculated per one million

thereby estimating its potential risk and the degree of follow-up. Further explanation

concerning risk and incident follow-up is found in the BWSC procedures for incident

reporting.

9.7 Dropped objects Dropped objects are dangerous occurrences, which may lead to severe personal injuries.

Objects with energy above 40 Joule (J) should be considered potential fatalities – see red area

10 Emergency Procedures

10.1 Emergency response plan

The detailed emergency response plan will depend on project specific conditions, ie. whether

the construction site is situated within or near an existing power plant or industrial complex

with specific safety hazards. In such cases, the emergency response plan will need to take

into consideration such special risks and may require close cooperation with responsible parties

with respect to evacuation procedures.

The following can serve as a guideline when preparing the emergency response plan:

Type of incident

What to do

Work Accident

Stop the accident without exposing yourself to danger.

Supply first aid assistance to the victim.

Call local emergency centre if necessary.

Fire

Activate fire alarm.

Prevent the fire from spreading to surrounding areas

Try to extinguish the fire without exposing yourself or

others to danger.

Help injured persons.

Call local Fire Brigade if necessary

Environmental

Incident

Try to stop the environmental incident if possible,

without exposing yourself or others to danger.

Help injured persons.

Call local emergency centre if necessary

Assistance

In case of criminal incidents inform the Site Manager

immediately.

The Site Manager will notify the police and other parties

as required.

In all cases: Notify the Site Manager as soon as possible.

10.2 Certified emergency responders (First Aiders)

BWSC Site Manager and supervisory

personnel shall have completed training

as certified emergency responders (First

Aiders) from a recognized training

institution. This includes training in CPR.

A poster with names, mobile phone

numbers and photos of first aiders shall

be maintained and posted on the safety

notice boards.

10.3 First aid equipment At the time of mobilizing the site, BWSC will have available a comprehensive set of first aid

equipment, including oxygen mask, cardiac pulmonary resuscitation (CPR or cardiac

defibrillator) equipment and a stretcher.

It is the responsibility of the site safety officer that the first aid equipment is checked regularly

and replenished as required.

The first aid equipment shall be available and easily accessible at all times. Signage on the

building shall indicate the location.

10.4 First aid response First aid with small accidents

In case of small accidents, ie. cuts, scratches etc., first aid can be

carried out on site by the site safety officer or any of the certified first

aiders.

In case of serious accidents more systematic efforts are required.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


30

Start first aid as required by the situation

Call the safety officer or someone from site management quickly.

Investigate the seriousness of the accident.

Call an ambulance if required and make sure that somebody guides the ambulance to the

accident area.

10.5 Electrical accidents Do not touch the person before electricity is cut off.

Start first aid, including cardiopulmonary resuscitation (also

called heart-lung massage or CPR) and mouth to nose ventilation

method if necessary. Use oxygen equipment according to given instructions. Call an ambulance.

Electrical burns are treated by cold water on the burnt area until the ambulance personnel

take over

10.6 Burns

Burned places on the body shall be continuously flushed with water. Burned arms and legs

shall be held submerged in water (e.g. in a bathtub filled with water or similar) until the

ambulance arrives.

10.7 Acid burns

Immediately pour water over the burned part of the body

Remove clothing

In case of acid burns in the eyes, rinse with water from an eye

wash bottle or any other source of clean water

All acid burns require immediate hospital treatment.

10.8 Poisoning

To secure proper treatment in poisoning cases the hospital shall be

contacted right away and informed about which materials the

poisoned person has worked with.

10.9 Accidents involving the back and the neck

A person who may have suffered injuries to his back or neck shall only be moved by

experienced persons or under a doctor’s advice. It is important that personnel suspected of

having injuries to their neck or back are stabilised – i.e. put on a neck collar or use other

means to stabilise the head - until professional assistance arrives.

10.10 Fire protection and prevention

In case of fire the following guidelines will apply:

A fire requires three elements: Heat, combustible material and oxygen.

The fire is prevented or extinguished by removing any one of the three

elements.

Fire is prevented through good housekeeping, proper maintenance and a

safe system of work when working with open flame or equipment which

produces sparks.

To ensure that personnel can be accounted for at all times every person

inside the site perimeter shall register when arriving on site and again

when leaving site

10.10.1 Fire evacuation plan

In case of fire:

1. Activate the fire alarm.

Klaxon horns or similar are located in the work site and at the

BWSC and contractor site offices. Alternatively use the temporary

alarm system installed.

a. Prevent the fire from spreading to surrounding areas.

b. Try to extinguish the fire.

c. Help injured persons.

2. Call the Fire Brigade

3. Evacuate the site

4. Assemble at the muster point

5. The fire wardens will make an account of the personnel

6. Await signal by the fire warden that work may be resumed

33

10.11 Oil spill contingency

10.11.1 Oil spill hazards

The most likely environmental hazard is the potential for oil spill, mainly diesel fuel, heavy fuel

or lubrication oil. The hazards may be present during bunkering operations, when receiving the

fuels or lubricants from tanker trucks or vessels or during testing and commissioning activities.

Similarly may small spills occur during fuelling of forklifts or other plant and equipment if care

is not taken.

10.11.2 Oil spill controls

Specific method statement and risk assessment shall be prepared before bunkering or fuelling

operations commence. The risk assessments will assess environmental hazards, fire hazards as

well as hazards related to personnel exposure to chemicals and fumes from chemicals.

Controls and emergency response shall be carefully planned to ensure that any spill does not

contaminate the ground or water at site. Mechanical connections shall be examined to ensure

they match, are in good condition and do not give rise to potential leaks. Double skinned

drums and tanks are preferred, alternatively the tanks and drums should be placed in a

bunded area.

Should a leak occur despite preventative measures taken a comprehensive oil spill

containment kit (absorbent sand, oil spill mats, spill trays etc.) shall beforehand be placed

close to the work involving chemical substances.

Specific local circumstances may require that more comprehensive oil spill kits are made

available, including barriers, booms, skimmers etc.

The Site Manager shall familiarize himself with the availability of specialized companies in the

area which can assist in case of larger spills.

10.11.3 Reporting

All spills shall be reported to the Site Manager.

10.11.4 Reporting to the environmental authorities

The local hazardous waste regulations will stipulate the requirements and procedure for

reporting spill incidents to the Environmental Agency. The Site Manager shall familiarize

himself with any applicable regulations and/or seek local advice. A standard reporting format

is included in the appendix.

34

Remember to do it safely – or not at all.

There is always time to do it right !

Subject: Common Activities

42

01 Common Activities

01.01 Housekeeping A neat and tidy work place is a major contributor to the prevention of accidents and to

increased work efficiency.

The following precautions shall be observed on BWSC work sites:

All areas being worked in shall be kept clean.

Walkways and scaffolding decks shall be kept clear, free from rubbish, tools, electrical

cables, materials, protruding nails, splinters, loose boards etc.

Access ways shall be kept in good condition.

Floors shall be kept free from oil, grease and water.

Any spillage shall be wiped up as soon as possible after being spotted.

Rubbish and scrap shall be removed to a disposal or storage area as soon as possible.

Waste bins shall be used throughout the construction site.

This will prevent that operatives are injured by tripping, stepping on or bumping into tools and

other objects lying around or by objects falling from above.

Maintaining good housekeeping at all times is a task which requires constant management

involvement and monitoring. From the start of the project all parties will be required to

demonstrate discipline and respect for good housekeeping.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


43

01.01.02 Dedicated Housekeeping Team

When several contractors or teams are working in the same area, each team shall be

responsible for the housekeeping relating to their own work. In practice however there may be

good , this may lead discussions about who shall do what. In such cases, it may be better to

employ a separate and dedicated team with no other task than to maintain good

housekeeping.

The Site Manager and Supervisors shall ensure that arrangements are in place so that

materials and waste generated during construction will be removed from scaffolding and

footpaths/access routes on a daily basis.

As a general rule, every individual shall clean up after himself at the end of the day, including

placing tools and equipment in the designated tool stores. Once a week, time shall be set aside

to a more thorough general cleaning of the work areas.

01.01.03 Waste Categories

Local rules and regulations will determine

the requirements with respect to sorting

waste and refuse in various categories.

The Site Manager will familiarize himself

with such requirements.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


44

01.01.04 Control of Dust etc.

Under dry conditions and where dust

could otherwise be generated, roads and

debris shall be sprinkled with water to

minimize the resulting health and safety

hazards.

01.02 Fire Prevention

01.02.01 The Fire Triangle The fire Triangle is a simple model for understanding fire. It

illustrates a fire requires three elements: Heat, fuel and

oxygen. The fire is prevented or extinguished by removing

any one of them.

Looking at the work place, the factors listed below shall be

considered when reducing the risk of fire.

Good housekeeping reduces the risk for fire.

Electrical installations shall be kept clean and protected against accidental cutting,

hammering, etc.

Smoking is only permitted in designated places.

Flammable fluids shall be stored in their original packaging and in designated areas. All

use shall be subject to the relevant safety precautions.

Special safety instructions apply to hot work, ie. any type of welding, soldering and

flame cutting. Please refer to Section 3 under mechanical erection.

LED lamps shall be preferred to illuminate work areas – they consume less power and

consequently present a reduced fire hazard. If halogen lamps (flood lights) are to be

used they shall be securely fastened.

Gas cylinders, such as LPG, acetylene and oxygen shall be kept in proper trolleys or

baskets, fully secured with straps. When not in use, the valve fitted to the cylinder shall

be closed. Cylinders shall be capped when the regulator is removed.

Fire extinguishers shall always be in good working conditioning and easily accessible.

Extinguishers are subject to regular inspection and re-fill according to the date labels.

As a minimum, two different types of extinguishers, ie. CO2 and Foam Extinguishers

shall be available throughout the site.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


45

01.02.02 Spontaneous Combustion

Spontaneous combustion occurs when a fire starts by itself, without an external ignition

source. Substances with low ignition temperature exposed to oxidation or bacterial

fermentation may begin to release heat. If the heat cannot escape, the temperature may rise

above the ignition point and the material will self-ignite and burn.

Materials likely to be affected by spontaneous combustion, and which are commonly found in

the work place is clothing, rags or other fabrics that have been in contact with oil. Such

material shall immediately after use be removed from the work area and kept in a closed steel

drum.

In biomass plants, various types of fuel may be subject to self-ignition, such as wood chip

piles, haystacks, seeds containing oil or animal manure. Special guidelines are available and

shall be consulted in these circumstances.

01.02.03 Fire Emergency Response

More detailed instructions are given in this manual Part 1, Chapter 10.05.

01.03 Working Clothes Suitable work clothes in proper condition shall be worn at all times. Normally full-body work

clothes are required, however in hot conditions and where the risk of fire is small or negligible

T-shirts may be allowed at the discretion of the site manager.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


46

01.04 Personal protective equipment

(PPE) Personal protective equipment shall be selected and used

when workplace hazards cannot be eliminated or

controlled by other means.

Certain PPE shall always be worn on site – see symbols on

the right. Risk assessments shall be carried out and used

to determine the need for additional PPE.

PPE shall NOT be the primary or only means of controlling

hazards. Always try to eliminate or avoid the hazard in

the first place.

Hard hat, safety glasses, hi-vis

vest or jacket, gloves and safety

shoes or safety boots is

mandatory PPE on all BWSC work

sites

Mandatory personal protective equipment

on BWSC sites:

When grinding, chipping and cutting or when working adjacent to such work, safety goggles

and ear protection shall be worn. Respiratory protection, e.g. filter masks or disposable masks

may also be required in situations when dust is created.

During welding operations the welder shall wear gloves, eye/face protection mask. If the

natural ventilation is insufficient mechanical exhaust ventilation shall be installed and used.

Special rubber (nitrile) gloves, apron, boots and full face shield shall be used if the worker

works with acidic or caustic media.

Whenever diesel engines or other noise generating equipment is in operation, ear protection is

mandatory.

The responsible supervisors shall make available appropriate equipment to satisfy the above

requirements. PPE shall be CE marked or similar and maintained or replaced as appropriate.

The Site Manager may dispensate from the general requirement to wear safety glasses,

hard hat or gloves in cases where the PPE does not add safety, e.g. termination of cables could

be difficult while using gloves. Another example: The use of hard hat and safety glasses is

probably not required inside the control room.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014

01.05 Hand Tools and Power Tools

01.05.01 Electric Hand Tools – testing

General precautions

Before using any electrical power tool always ensure that the electrical connections,

plugs, cable insulation and extension cords are intact and without damages.

All hand tools should be either earthed or double insulated.

All extension leads shall be fully extended to prevent overheating.

Always use a machine of type, size and capacity appropriate to the work.

Charging points for battery powered tools shall only be used in dry and safe areas of

permanent or temporary buildings.

Use proper drill size in accordance with the drilling machines capacity.

Adjust the pressure applied to the drilling machine to the actual working position and

material to be drilled.

Be prepared for an abrupt stoppage of the drill bit.

Never drill in loose material, always secure the material before drilling operation

commences.

Testing (PAT)

Electrical hand tools/power tools shall be

subject to regular testing.

In the UK: Portable Appliance Testing (PAT testing) as

follows:

Double insulated tools: Every 6 months

Other electric tools: Every 2 months

In other countries follow local rules and regulations.

The testing includes the following:

Check that cable and the insulation is intact

Check that the plug and cable relief arrangement is intact

Check that the appliance (housing etc.) is intact

Check that the appliance is in working order

Appliances that fail the test shall be marked “Do not use” and set aside for repair or disposal.

All repairs shall be performed by a skilled electrician.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


48

After successfully completing the test the

appliance shall be clearly marked with a

suitable label.

01.05.02 Grinding and Cutting Tools

Use the correct disks for the task (cutting or grinding) and the material.

Ensure that the grinder operates with the correct speed for the disc.

Attach the grinding disc properly, using the correct tools.

Guards shall be correctly positioned and properly adjusted.

Use the grinding-cutting machine correctly only applying correct pressure

Always remove loose hanging clothing before commencing operation.

Disc cutters shall only be used when standing on a firm, level base.

Wait until the disc stops spinning before laying down the machine.

Be careful not to place the machine so the disc can get wet.

Be aware of sparks being emitted. When grinding in an area where other people are

working or may pass by, make sure that sparks are contained. This can be done by

shielding the area by temporary, movable walls or curtains.

01.05.03 Compressors and Pneumatic Tools

Compressors/ tools are subject to planned maintenance and regular inspections.

Air receivers shall be fitted with pressure gauge, safety valve, drain point and access

for cleaning.

The safe working pressure shall be identified on all air receivers.

All guards and covers shall be fitted over moving parts of compressors, especially on v-

belts and pulleys.

Cutting tools provided are to be kept sharp and should be held securely in their fitment.

Ensure that hoses are the right size for the tool and that the length of the hose is kept

as short as possible.

Hoses shall be kept free from corrosive materials and protected from interference by

passing traffic.

Hoses shall be kept clean when disconnected.

All connections shall be properly clamped to prevent the hose whipping.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


49

01.05.05 Machine Tools

A common machine tool used during construction work is the pipe threading/cutting machine.

The following precautions shall be observed:

When piping is operated in the pipe threading/cutting machine and extending beyond

the machine, the operator shall make sure that the pipe is free to turn and properly

supported.

Fittings shall not be applied to the threaded pipe while in the machine.

Cutting of pipes in the machine shall only be performed if the machine is equipped with

a proper cutting tool. Never use a hack-saw while the pipe is spinning.

Threading and/or cutting of pipe where fittings already are mounted shall never be

performed in the machine.

Always make sure that the electrical cord to the machine is undamaged.

Do not allow cutting oil to spill onto the floor. It causes a slipping hazard

and damages the concrete. Use a suitable bucket to collect any overflow

and keep absorbent sand at hand.

01.06 Working at Height

01.06.01 General precautions

Work above 2 meters shall be carried out using scaffolding or mobile Elevated Work

Platforms (MEWP).

Safe means of access and egress shall be established and maintained.

Erect signs and barriers directly below works to warn of overhead operations.

Erect edge protection at all openings or edges ie. main guard rail at 1000 mm above the

floor level, a mid-rail 500 mm above floor level and a toe board at least 150 mm high.

Where edge protection is not practicable identify alternative means of fall prevention/fall

arrest or work restraining system. See below.

To protect third parties against debris falling, chutes, or full enclosures shall be installed.

All equipment used shall be checked to ensure it is in good working order, to correct

specification, and in date for inspection.

01.06.02 Fall Arrest and Work Restraint Systems

Providing adequate platforms and edge protection may not

always be possible or reasonably practicable. If so, either

safety nets or harnesses will be required. They do not stop

people falling but can minimize the potential injuries after a

fall.

If nets are used, make sure they are properly installed by

competent riggers.

There are two types of harness protection that a person can

use:

Work Restraint System - this stops a person from falling in

the first place

Fall Arrest System - this stops the person after he has

fallen

If harnesses are used, make sure they are fully intact, including lanyard, shock absorbing

mechanism and/or retractable device. Check that the inspection date on the harness is valid.

They shall be securely attached to a strong anchoring point above the person using it. Using

harnesses require user discipline and active monitoring by management.

When using a fall arrest system, due consideration shall be given to the rescue of a person

suspended in the lanyard. A procedure and suitable equipment shall be in place before the

work commences.

1. A rigger is a dedicated person who attaches or releases a load from a crane hook.

2. The rigger shall work closely with the crane operator and he shall be authorized by his

superior or a rigger after sufficient instructions.

3. The rigger shall reject any slings and other lifting gear, which is damaged.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


55

4. The rigger shall be informed about the weight of the load to be lifted.

5. The rigger shall be informed about special loads, which shall be rigged in a certain way.

Slinging

1. Slings and lifting gear shall be clearly marked with safe working load (SWL).

2. All slings and lifting gear shall have a SWL certificate.

3. Special lifting gear shall only be used for its intended purpose.

4. Slings and lifting gear shall be kept and stored properly.

5. Slings and lifting gear shall be kept clean, so that it is possible to read the safe working

load marking and inspect for damages.

6. Allowance should be made for increased loading on the eyebolt when angled slings are

used.

7. Use the longest sling practicable to reduce the angle between the legs of the sling.

8. The size of the sling should be adequate for the load being lifted.

9. Slings should be protected from sharp edges by suitable

packing.

10. Slings should not be knotted, and wire slings made up of wire

clamps are not allowed to be used for lifting operations.

11. When using slings on machine components, protect the part

with wood, cloth or use a special soft sling designed for this

purpose.

12. The tip of a hook is relatively weak and should not be used for lifting.

13. The load should be slung centrally to avoid eccentric loading on the hook.

14. A safety catch shall be used to prevent load displacement from the hook.

15. Never attach a sling to a finely machined surface such as the journal bearing of a shaft.

16. Make sure the slings are free from kinks.

17. Items may never be lifted in one point only unless a special lifting point on the lifting

device has been provided.

18. Items may never be lifted in a sling just passing unlocked over the hook, if it is

connected to 2 individual points.

19. As soon as the load is lifted off the supports check the wires before carrying out further

handling operations.

20. The BWSC supervisor shall ensure that all rigging for heavy lift operations is approved

by competent person before start of operations.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


56

Sling Angles

Lifting Beams

Lifting beams (also called spreader beams) are used in slinging/rigging to distribute the load or

keep slings in required positions.

Some lifting beams are custom made and supplied together with the equipment they are

designed to lift. As an example, the chimney sections are often supplied with the lifting beam

used for erection of the chimney sections. Another example is the lifting beams used for heavy

lift of diesel engines and generators.

Handling of roof or wall panels are often done by special lifting beams/attachments. Special

attention shall be given to handling these light objects in windy conditions.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


57

Examples of lifting beams:

Adjustable spreader beam Simple lifting beam Four point spreader

Lifting beams shall be marked with SWL and only used according to their intended purpose.

Eyebolts and Shackles

1. Certain eyebolts, particularly those without collars, or those with welded collars are

unsuitable for general lifting purposes. Use the correct eyebolt for the job and make

sure it is screwed firmly onto the joint faces and that its collar is properly seated.

2. Safety allowance should be made for increased loading on the eyebolt when angled

slings are used.

3. When using a shackle use the appropriate pin. Do not use a temporary pin.

4. The suspension or anchoring point to which any tackle is attached should be as strong

as the lifting tackle itself.

Eyebolt Shackle Collar

01.07.03 Examination of slings and lifting gear

Slings and lifting gear shall be thoroughly examined by a competent person at least once every

12 months. These inspections shall be recorded by the Site Safety Officer.

01.07.04 Hand signals for Lifting Operations



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


60

01.07.05 Heavy Lift Operations

The heavy lift procedures for transportation, unloading, sliding and positioning of engines and

generators are subject to individual analysis, Method Statement and Risk Assessment. The

operations will always be under direct supervision of authorized specialists from BWSC or a

BWSC appointed person.

01.07.06 Forklifts and Telehandlers

A forklift or telehandler (forklift with a telescopic boom) shall never be loaded above the limit

stated on the fork lift marking plate. It is the operator’s responsibility to know the weight and

the approximate centre of gravity of the load.

The driver shall always make sure that he has a clear view in the driving direction. If this is not

the case, or when working in congested areas, a banksman shall be used.

The driver of a forklift shall be trained in forklift operation and possess a valid certificate in

accordance with the local regulations.

Daily inspection/checks by the operator shall be made including brake testing. These checks

shall be recorded.

Safety Precautions:

Always drive with the forks in low position and the frame tilted back.

Do not drive with passengers.

Always watch clearance during lifting or lowering.

Be extremely careful with transport of long items.

Never drive if load is not safely loaded. Palletised loads shall be checked for safety

before lifting.

The load shall never be carried above other persons.

Pay attention to the stability of a fork lift truck which can be adversely affected by such

things as uneven, soft, slippery or sloping ground, rapid turning, breaking or

accelerating.

If the fork lift truck is operated inside a building, adequate ventilation will be provided

to disperse any fumes generated by the engine. Electrical trucks shall be preferred.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


61

Fork lift trucks shall be fitted with safety belt and this shall be used by the operator.

Roof windows shall be fitted with a protection grille or similar.

If a telehandler is equipped with a lifting attachment, the rules and precautions listed under

cranes shall apply.

01.08 Working with Substances Hazardous to Health

Many substances have the capacity to cause injury to personnel. The injury may be

immediately apparent, or it may take years to manifest itself.

Some substances used at work are obviously dangerous e.g. sulphuric acid. But many

substances used at work are not obviously hazardous and the injury or damage sometimes

appears unexpectedly after a period of time. Hazards may be biological, chemical or physical

and include fire and explosion.

Handling of chemicals shall be carefully considered and a risk assessment worked out.

United Nations Hazard Symbols (UN Globally Harmonized System of Classification and

Labelling of Chemicals (GHS):



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


62

01.08.01 Material Safety Data Sheets (MSDS)

A material safety data sheet (MSDS) shall be available on site for all substances with potential

harmful effects. The MSDS provide workers and emergency personnel with procedures for

handling or working with that substance in a safe manner and includes information such as

physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid,

reactivity, storage, disposal, personal protective equipment and spill-handling procedures.

It is important to use an MSDS specific to both country and supplier, as the same product (e.g.

paints sold under identical brand names by the same company) can have different formulas in

different countries.

The Site Safety Officer will maintain a file of MSDS as part of the safety files. In addition,

relevant MSDS may be posted in the actual work place, near to the place where the substance

is used and stored.

It is the responsibility of the Supervisor to familiarize himself with the MSDS for any

substances handled under his scope of work, and to ensure that necessary guidelines are

communicated to and followed by the personnel working with these substances.

01.08.02 Control of Substances Hazardous to Health

Based on the information obtained from the MSDS and other sources, an assessment can be

prepared with respect to the necessary controls (in UK regulations referred to as the COSHH

assessment - Control of Substances Hazardous to Health).

This will include an assessment of:

Potential hazards.

Frequency and duration of exposure.

Control Measures, including necessary PPE to be used, training of operatives, emergency

procedures, safety signage etc.

General Precautions

When chemicals arrive on the Site, check container labels and consignment notes, to

make sure that the goods are supplied as ordered.

Check that the containers are not damaged.

Ensure that handling and storage arrangements are in accordance with the suppliers

warning labels and instructions.

Ensure that different chemicals are kept apart, to ensure that if a leakage should occur,

incompatible chemicals would not come into contact.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


63

Display hazard warning signs at the entrance to the store if appropriate.

Never mix different chemicals, even in small quantities, without the manufacturer’s

recommendation or instructions. Mixing of different chemicals may produce a

dangerous reaction.

Operatives shall be provided with a suitable barrier lotion or appropriate gloves when

they undertake work, which may cause skin damage.

Use protective clothing and goggles/face shield as appropriate.

When required, appropriate ventilation apparatus shall be used.

If there is a danger of a contamination of the skin or eyes an emergency shower or

other means of washing facilities shall be provided close to the place of work.

Eyewash facilities shall be available, conveniently located and marked.

If there are signs of a person having been exposed to dangerous/poisonous materiel, i.e.

showing symptoms of headaches, dizziness, looking intoxicated or very tired, correct medical

treatment shall be provided right away. The doctor shall be informed of which substances the

injured person has been working with.

01.08.03 Asbestos and Man-made Mineral Fibres (MMMF)

Asbestos was earlier a very common material used in buildings as well as mechanical and

electrical equipment. BWSC will never use Asbestos in any new installations.

If asbestos is present in existing installations where BWSC shall undertake work, this shall be

subject to a job-specific Method Statement and Risk Assessment under the guidance of

asbestos specialist advisors.

01.08.04 Working with Explosives

Work with explosives shall follow local and general rules for storage, transport and use of

explosives. The work will be subject to job-specific Risk Assessment and Method Statement.

01.08.05 Radiation / working with radio-active materials

All radioactive material on site shall be properly marked and

stored in accordance with international law.

Use of radioactive source or x-ray for material control shall

take place when other workmen are not at the work site. If

this is not possible, proper marking and warning shall be

given by the operator before using the radiation source or

releasing it from its protective shelter.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


64

If a person has been exposed to a radioactive source, medical treatment shall be sought

right away and the Safety Officer shall be advised. It is also important to find out where the

affected person has been and for approximately how long, such that the doctor can be

correctly informed of the potential dose of exposure to radiation.

Always remember radiation is dangerous and that you cannot see, smell or hear it.

Always be extra careful and follow the x-ray operators’ advice.

01.09 Working in Confined Spaces

01.09.01 Confined space definition and examples

A confined space can be any space of an enclosed nature where there is a risk of death or

serious injury from asphyxiation, fire or explosion.

Examples of Confined Spaces

Specific examples of areas which, depending on the work being

undertaken may come under the definition of a confined space:

Storage/service/buffer/run-down tanks (fuel, lubricants, water)

Flues, chimney stacks

Exhaust gas silencers

Ductwork (air intake, exhaust, ventilation)

ID Fans

Diesel engines’ housing, generators

Vessels

Boilers

SCR Reactors

Silos (urea granulate)

Excavations, tunnels etc.

Data floors and similar places where egress may be difficult

01.09.02 Typical Hazards to consider in Confined Spaces

The most likely hazards that can occur in a confined space are:

Lack of oxygen

Poisonous gases, fumes or vapour

Liquids and solids which can suddenly fill the space

Fire and explosions

Residues left in tanks etc.

Dust in high concentrations

Hot conditions leading to dangerous rise in body temperature

http://www.google.dk/url?sa=i&rct=j&q=&esrc=s&frm=1&source=images&cd=&cad=rja&docid=2y9AcHBfGTTzNM&tbnid=t0WfgurTH7TcoM:&ved=0CAUQjRw&url=http://www.usmra.com/repository/PHOTOS/Confined_Space/index.html&ei=QwXqUrrzJueK4ASVhoCwDw&bvm=bv.60157871,bs.1,d.bGQ&psig=AFQjCNEcc0LIaUdgm4CtSP7iTSYjPyIgWw&ust=1391154134239254



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


65

Apart from these, all usual hazards which can be found outside the confined space may also be

present inside the confined space. This includes electricity or mechanical equipment. Where

these hazards are present in a confined space the precautions will almost always be more

extensive than where they appear outside the confined space simply because of the enclosed

nature of the space.

01.09.03 Risk Assessment

Any work in confined spaces requires a Risk Assessment to be carried out by a competent

person.

If the Risk Assessment identifies risks of serious injury from work in the confined space, the

following key duties will apply:

If at all possible, avoid entry into the confined space

If entry is unavoidable, follow a safe system of work

Put in place adequate emergency arrangements before the work starts

01.09.04 Work planning – avoid or reduce entry into confined spaces

Good work planning or a different approach can reduce the need to enter the confined space or

at least reduce the frequency of access to the confined space. Some work may be done from

the outside (pre-assemblies, extended tools etc).

01.09.05 Safe System of Work

The following checklist includes some essential elements:

01 Appoint a supervisor with the responsibility to ensure that the necessary preparations

are made and that suitable precautions are taken.

02 Appoint a person, who is placed outside the confined space at all times during the

works.

03 Deploy only persons suitable for the work (correctly trained, physical build, experience,

medical condition etc.).

04 Mechanical and electrical isolation of equipment which could inadvertently be operated.

Check that isolation is effective.

05 Clean before entry.

06 Check the size of the entry. Is it big enough for workers wearing all the necessary

equipment to climb in and out easily and provide safe access and egress in an

emergency?

07 Provision of ventilation. It may be necessary to increase the number of openings or

provide mechanically forced ventilation.

08 Testing the air may be necessary to see if it is free from toxic or flammable vapours

and fit to breathe. Suitable gas detectors shall be used by a competent person.

09 Provision of breathing apparatus may be necessary. Never try to “sweeten” the air in a

confined space with oxygen as this can greatly increase the risk of fire or explosion.

10 Provision of special tools and lighting may include non-spark tools and specially

protected lighting or use of low voltage equipment.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


66

11 Fire fighting equipment and a fire warden shall be in place before hot work starts.

12 Emergency arrangement shall be in place, and includes equipment, training and

practice drills.

13 Rescue harnesses shall have a lifeline running back to a point outside the confined

space.

14 Communications shall be adequate, reliable and tested between people inside and

outside the confined space.

01.09.06 Permit to Work

Confined space work requires a Permit to Work in which comprehensive controls are described

including the need for a contingency plan for rescue of the person(s) inside the confined space.

Remember that the confined space work also needs to take into account other work on site

which may result in a fire alarm or otherwise affect the confined space work.

01.10 Lightning Safety In locations prone to thunderstorms, the Site Management shall implement this Lightning

Safety Policy. The policy covers the following safety issues:

Awareness

Warnings and precautions

Safe places

First Aid in case of lightning

01.10.01 Awareness

Everybody on site shall be aware of the hazards, dangers and precautions associated with

lightning. Consider to incorporate safety awareness of lightning in the site safety induction

program and in the site rules. Use tool box talks and site safety notices to ensure the

necessary guidelines are known to people.

01.10.02 Warnings and precautions

The weather forecast is the obvious source of information when planning the work activities

that are prone to risk of lightning. However, the forecasts may not be accurate, and

thunderstorms can occur at very short notice. Take notice of early signs of thunderstorms:

high winds, dark clouds, rain, distant thunder or lightning.

Activities which are particularly risky during lightning include crane work, erection work and

work on or near tall structures. Keep in mind that some work activities cannot easily be

abandoned with short notice.

If these conditions exist, do not start a task you cannot quickly stop. Examples of such

activities are heavy lift operations and pouring of monolithic concrete structures.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


67

Consider the measures necessary in case a job has to be aborted at short notice. Consult

specific Risk Assessments and Method Statements where applicable.

01.10.03 Safe places

Access to a safe place is not always readily available on a construction site, and therefore,

shall be planned in advance. Since there is no safe place outdoors, the only safe shelters will

be buildings and vehicles.

A safe building is one that is enclosed with a roof, walls and floor. A structural steel building

where the cladding roof and walls are not yet installed can also be considered safe, as the steel

structure will provide a Faraday’s cage. It is required however, that sufficient steel is in place

so as not to leave major open gaps in the structure. Once inside, stay away from plumbing and

pipework, electrical cables and electronic equipment unless these items are not yet connected

to any outside structure.

Unsafe buildings include work areas covered by a sun shade roof only, open garages, covered

patios, lunch/coffee break shelters or sheds.

A safe vehicle is any fully enclosed metal-topped vehicle.

Backhoes, bulldozers, loaders, graders, scrapers, mowers, and other heavy equipment that

employ an enclosed rollover systems canopy are safe in nearby electrical storms. The operator

should shut down the equipment, close the doors, and sit with hands in lap, waiting out the

storm. While inside a safe vehicle, do not use electronic devices and avoid touching any metal

parts. Under no circumstances during lightning should the operator attempt to step off the

vehicle in an attempt to find another shelter.

Unsafe vehicles include convertibles and open cab construction vehicles without any roll over

canopy. The rubber tires of a vehicle do not provide any safety against lightning.

Assess your lightning risk and take appropriate

action.

During thunderstorms no place outside is safe.

If you can hear thunder, lightning is close enough

to strike.

Stop what you are doing and seek safety in a

substantial building or a hard-topped metal vehicle.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


68

How far away is the lightning?

Count the number of seconds between a flash of lightning and the sound of the

resulting thunder.

Divide this number by 5 to get an estimate of the distance in miles to the lightning

strike.

Each second corresponds to a distance of one kilometre

Remember, if you are outdoors and can hear thunder, you are in danger of being struck by

lightning.

01.10.04 First aid if a person is struck by lightning

Lightning victims do not carry an electrical charge. They are safe to touch and need urgent,

medical attention. Cardiac arrest is the immediate cause of death for those who die.

Some deaths can be prevented if the victim receives the proper first aid immediately.

Call Emergency Ambulance and perform CPR if the person is unresponsive or not breathing.

Use an Automatic External Defibrillator if needed.

02 Civil Works

Civil Works are normally subcontracted partially or in whole to local subcontractors. It will be

part of the subcontractor’s responsibility to provide risk assessments for the activities under

his scope of work.

BWSC however maintain the overall responsibility for implementation of a management

system. For this purpose, the following guidelines are provided.

02.10 Excavation Work

All excavation work is to be planned in such a way that safety

hazards are minimized and controlled.

When working on construction sites within existing industrial

facilities, special precautions shall be taken with respect to any

underground and/or overhead services, as well as the potential

for contaminated soil.

02.01.01 Excavation Permit

In some cases where specific risks are

identified, such as underground obstacles or

special soil conditions, a “Permit to Excavate”

may be required. Where such system is in

place, no excavation may be carried out

without an Excavation Permit signed by the

person in charge.

A sample format is included in Appendix.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


73

02.01.02 General Precautions

Excavations shall be clearly marked all around. When required warning signs, including

electric warning lights shall be installed and maintained at all times.

Concrete barriers shall be placed where there is a risk of wheeled traffic coming close to

the edge of the excavation.

Materials shall be stock piled clear of the edge of the excavation.

Excavations should be back filled as soon as practicable.

All excavations that are to be accessed by persons and deeper than 1 m shall be

supported/shored or the sides battered, such that these are no steeper than 35 degrees

unless a qualified civil engineer determines otherwise.

Safe means of access to the excavation shall be established.

When designing the excavation support system, proper account shall be taken of the

loads from the surroundings, including traffic load and vibrations.

No change to the slope or shoring shall be made without prior approval.

Where flooding risk occurs, cofferdams/caissons to be installed with pumps of adequate

capacity.

02.01.03 Underground Services

Full details of underground services shall be obtained in advance from the owner, utility

or relevant authority.

Existing drawings to be utilised to trace buried services.

Accurate location of underground services by operatives trained in

the use of locating equipment such as cable scanners.

Trial holes may have to be dug by hand to confirm locations, taking

into account physical indicators such as junction boxes, manholes

and ground conditions.

The lines and depths of services to be marked, using paint, wooden

pegs, etc. before work begins.

Hand digging may be required in many cases.

CAT cable

scanner

All services are to be assumed to be live until proven otherwise - written confirmation

required.

Services crossing excavations to be supported.

Work to be supervised at all times.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


74

02.01.04 Use of Excavators and Heavy Equipment

Planned maintenance programme applies to excavators and other earth moving

equipment. Inspection register shall be completed.

Excavators and other plant to be operated by trained, certificated and authorised

operators

180 degree machines: When using the backhoe the bucket shall be lowered to the

ground.

360 degree machines: At least 600 mm clearance to be allowed for tail swing.

No persons are allowed to stand inside or work within the operating radius without the

operator’s specific permission.

Bucket/arms shall not be slewed over personnel, vehicles cabins or huts.

Travel and operations on a gradient shall be controlled to ensure machine stability.

On wheeled excavators it is essential that the tyres are regularly checked for condition

and correct tyre pressure.

Banksmen are to be used where the driver’s vision is impaired or he is operating under

congested conditions. Large excavators shall never be permitted to travel in a confined

area or near people without a banksman to guide the driver.

Machines shall not be refuelled whilst engine is running. Necessary precaution shall be

taken to prevent oil spill.

Trenching/deep excavation work shall be supervised to ensure the stability of the

machine and excavation.

Particular attention shall be paid to electrical lines overhead.

02.02 Concreting Works

02.02.01 Work with reinforced concrete

Working with reinforced concrete involves a great deal of manual work. When reinforcement is

cut and bent on site the contractor will establish a separate area for this work. An important

safety factor is properly organizing the area maintaining good housekeeping. The flow of

material – mainly steel bar- shall be planned and the cut-off collected in a suitable manner.

Cranes offloading steel bars, or loading sub-assemblies such as foundation baskets, should not

slew over the people operating the cut and bending machine.

Once the reinforcement bars are placed in situ, all protruding ends shall be capped with plastic

“mushrooms”.

02.02.02 Installing and stripping of formwork

The installation and subsequent stripping (removing) of formwork often involves the use of

cranes. Consequently, the precautions listed in this manual under “Lifting Operations” shall be

observed. Whether pre-fab panels are used, or the formwork is constructed in situ, manual



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


75

work will be necessary, involving stairs, scaffold and platforms. The relevant precautions for

such activities are described under “Working at height” – see chapter 01.06.

02.02.03 Mixing and placing concrete

When using ready-mix concrete, the potential safety hazards on site are

mainly related to risks of moving mixer trucks and use of concrete

pumps. Particularly, the hose from the concrete pump is a serious safety

hazard as it swings around over the area, and shall be carefully

controlled. In case the concrete is placed by using buckets lifted by

cranes, additional precautions shall be observed related to Lifting

Operations.

When using poke vibrators the operator is subject to vibrations through

his hands and body. The impact shall be minimized by use of good

equipment, work organization and PPE.

Where concrete is mixed on site, additional hazards shall be considered from the use of

hazardous substances and machines.

02.02.04 PPE when working with concrete

Skin contact with concrete may cause severe allergic reactions and shall therefore be

prevented. The use of protective skin cream / barrier cream is recommended. The use of

hard hats, safety goggles, safety boots and gloves shall be strictly enforced for all workers

engaged in concrete operations. Most likely the PPE needs to be supplemented with aprons

and full face shields if the operatives are in close contact with the concrete depending on the

risk assessment performed.

02.03 Demolition Work

This description refers to demolition of simple, internal walls, etc. and external single storey

outbuildings. Specific risk assessment shall be prepared in case of larger structures.

Ensure that all necessary permissions have been obtained.

Underground services to be located utilising site plans and location equipment.

Work area to be cordoned off utilising physical barriers.

Overhead power lines to be shrouded or disconnected.

Water, gas and electric services to be disconnected prior to work commencing.

Identify prior to work commencing whether the demolition area contains asbestos.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


76

Dust shall be controlled by dampening, housekeeping and local exhaust ventilation.

Associated noise known to be above the action level shall be controlled by work rotation

and barriers.

Work sequences to be planned and defined by site management.

Safe access and egress shall be maintained at all times

Suspicious substances or contamination to be investigated before work commences,

where contaminants are found during demolition process the area shall be evacuated

and tests carried out to ascertain the contents.

Monitoring shall be done continuously to ensure that all voids and open edges are

covered or fenced off.

Demolished material shall be disposed of at a controlled and approved tipping area.

In case asbestos or other contaminated building materials are found, all handling and disposal

shall follow local regulations and approved procedures. It will be necessary to prepare risk

assessments and involve specialist advisors.

02.04 Erection of Large Superstructures

The following structures are traditionally installed under the scope of BWSC Civil Works:

Structural and secondary steel erection for major buildings.

Installation of cladding systems on steel structure buildings.

Erection of Overhead Travelling cranes.

Erection chimney stack.

Site fabrication and erection of steel storage tanks.

Separate and specific Method Statements and Risk Assessments will be prepared for these

works.

02.04.01 Structural and Secondary Steel Erection

The hazards and necessary controls and precautions are mostly associated with lifting

operations and work at height. However, a safe system of work depends on erection

methodology, sequencing etc. which may vary from case to case, depending on availability of

cranes and other equipment. Consequently, a project specific Method Statement and Risk

Assessment will be required for these activities.

02.04.02 Installation of Cladding Systems

Basically, the same conditions will apply as mentioned above under steel erection. Again, the

cladding systems vary, from heavy concrete panels, over built-up systems to light sandwich

cassette systems. In case of light elements, the wind condition shall be monitored not to



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


77

exceed safe wind speeds. The erection methodology and types of equipment being used varies

accordingly, as do the safety hazards and controls.

02.04.03 Erection of Overhead Travelling Cranes

Basic hazards are associated with lifting operations and working at height. Additional hazards

shall be considered in connection with installation and commissioning of the electrical power

supply system. Overhead cranes are subject to regulatory testing. Legislation may demand an

independent 3rd party test with particular emphasis of static and dynamic load.

02.04.04 Erection of Chimney Stacks

Steel chimneys, whether lattice towers or steel casings, have the safety hazards associated

with lifting operations and working at heights. The heights involved are significantly more than

for other structures, usually 50 to more than 70 meters. Often two cranes will perform tandem

lifts, which further emphasises the importance of a well-planned work system and use of

proper equipment. Specific Method Statements and Risk Assessments shall be prepared.

In cases of concrete stacks, the hazards associated with concreting and slip forming/jump

forming will need consideration as well.

When welding inside the flues is required, the confined space rules will apply.

02.04.05 Erection of Storage Tanks

The fabrication and erection of steel storage tanks is subcontracted to specialised

subcontractors. However, it is the responsibility of BWSC Civil Works supervisor and Safety

Officer to ensure and monitor that a safe system of work is planned and implemented.

In case of smaller pre-fabricated tanks, the safety hazards are those associated with lifting

operations. In case of larger, on-site fabricated tanks, the hazards associated with work at

height, hot work and painting operations will also apply. Special hazards associated with use of

jacking systems may also be present.

The confined space requirements may be applicable for this type of work.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014

Subject: 03 Mechanical Erection

78

03 Mechanical Erection

This chapter covers the Mechanical Erection activities up to the point of filling with media and

pressurising the systems. For all activities associated with mechanical systems or subsystems,

after they are pressurised, please refer to the Test & Commissioning in Chapter 5.

03.01 Unit Erection A large proportion of mechanical equipment is unitized and arrives to site as subassemblies in

various stages of completion. Piping is also to a large extent unitized in the form of complete

pipe racks, or sets of pre-fab pipe spools. Consequently, mechanical erection involves a large

extent of materials handling, lifting operations and work at height, which are covered by

Chapter 1, Common Activities. This chapter will, therefore, deal exclusively with those

activities which are specific to the mechanical erection work, before systems are pressurised.

Illustration from BWSC Erection Guidelines for fuel separator units.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


79

03.02 Hot work

Welding, soldering, flame cutting and metal grinding are types of ‘hot

work’.

The ignition sources - heat, open flame or sparks - that are produced by

the hot wok may ignite flammable material in the vicinity of the hot work

area.

The following precautions will apply:

Correct and appropriate PPE such as gloves, boots, overalls, aprons and welding

goggles/face shield shall be worn in accordance with the risk assessment.

A specific risk assessment shall be carried out and used to identify and evaluate the

presence of flammable or explosive substances.

A hot work permit may be required.

Fire sentries / fire wardens shall be placed as required e.g. if there is risk of fire or heat

being transferred to adjacent areas.

Mechanical extraction of fumes from the work place shall be used. Specific risk

assessment shall be prepared which may evaluate if natural ventilation can be used in

place of forced mechanical ventilation.

Operatives shall check equipment at the start of shift and disconnect when not in

attendance.

Personal jewellery shall be not be worn by operatives.

All necessary fire prevention equipment and fire extinguishers shall be checked and

shall be in place prior to commencement of work.

Always ensure that an escape route away from the work place is established and tested

before work starts.

Adjacent personnel shall be protected from arc welding glare by use of barriers such as

curtains or other means of screens.

When metal grinding, the emitted spark beam shall be caught and stopped in a box, net

or plate placed in front the beam.

Before welding or flame cutting on the external of tanks, check that the tank is either

completely empty and clean or filled with water. If the tank cannot be filled with water,

it shall be checked by measuring, that the tank does not contain flammable vapours

(gas-free), and that the tank is kept open, so no pressure can build up during the work.

Proper ventilation of the tank during the work shall be ensured.

When welding or flame cutting inside tanks the tank shall be clean with no oil or other

flammable liquid. Before entering the tank check by measuring that the tank does not

contain flammable vapour and that adequate ventilation is available. Light and other

equipment used in tanks shall be a type intended for work in tanks (safety voltage). All

personnel working in tanks shall before work commences receive detailed instructions

from the supervisor about the safe working procedure.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


80

Hot work inside tanks is also controlled under the confined space requirements. Please

refer to chapter 01.13 in this manual dealing with confined space work.

03.03 Chemical Cleaning of Pipes

Chemical cleaning of pipes (“pickling”) will normally be subcontracted to specialist companies.

In cases where chemical cleaning operations shall take place on site, this shall be subject to

specific risk assessments that are prepared beforehand (COSHH).

In general, the following precautions will apply when working with chemical cleaning of pipes:

All proper PPE shall be provided and worn.

Necessary emergency procedures and first aid measures, including safety showers,

shall be provided.

All required safety signage shall be in place.

All relevant environmental controls shall be in place.

Hazardous liquids shall be disposed according to local regulation and approved

procedures.

Never add water to acid, always add acid to water. Rule: ‘A’ to ‘W’.

03.04 Work with Hydraulic Tightening Tools

In general, working with Hydraulic tightening tools requires special attention to safety

procedures, and safety precautions shall be followed at all times to minimize the risk of

accidents in case of equipment failure or other failures during the works.

1. When using hydraulic tools appropriate PPE such as safety helmet, safety shoes, and

especially eye protection and gloves shall be used to prevent injury from spray of high

pressure hydraulic oil or in case of a hydraulic hose or pipe fracture.

2. Always inspect the tools for damage before using it on the works. Never use damaged

hydraulic tools, hoses, connectors or jacks. In case of doubt please contact the

supervisor or the Site Safety Officer.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


81

3. Always make sure that the hydraulic equipment is suited for the work. The maximum

safe working load or pressure on hydraulic jacks and hoses shall not be exceeded.

4. A safety zone shall at all times be kept clear around and above the hydraulic equipment

to prevent injury in case of equipment failure or fracture of the bolt being tightened.

5. Please note that crack propagation and fracture of bolts have been experienced due to

material defects, notch effect related, corrosion fatigue and other faults.

6. Always carefully follow manufacturers’ instructions.

7. Please see below photo showing an example of a safety zone, where you shall not, for

any reason, be inside or lean into, with any part of the body.

03.05 Pressure Testing

Normally pressurized tanks and receivers are supplied with a pressure certificate from the

supplier. These will therefore not require any further testing on site.

In cases where pressure test of tanks or receivers is carried out on site,

and when pressure testing pipe work, the relevant safety hazards and

precautions shall be evaluated.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


82

03.05.01 Pressure Testing Hazards

The main hazard when pressure testing is the unintentional release of stored energy. Pressure

testing using a liquid as the pressurizing medium (hydraulic testing) is by far the safer method

compared to pneumatic testing because the energy levels are significantly lower (typically 200

times lower).

Consequently pneumatic pressure testing shall NOT be used on BWSC work sites.

03.05.02 Precautions

The following precautions shall be observed:

1. The pressure test shall be carried out with water or diesel oil.

2. It is NOT allowed to pressure test systems or equipment by use of air or other gas.

3. The system being tested shall be totally filled with liquid and properly vented to exclude

air pockets.

4. A pressure pump shall be used to achieve the test pressure.

5. Test pressure is normally 1.5 x working (operating) pressure or 1.5 x the design

pressure depending on the code applicable for the system.

6. The duration of the pressure test (constant pressure) is normally one (1) hour.

7. The work areas shall be cordoned off and proper safety signage shall be in place.

8. The test personnel shall advise other personnel about the test being carried out.

9. All pipe connections from tanks or receivers shall be closed.

10. All instruments, except the test pressure gauge, shall be disconnected.

11. The safety valve (relief valve) shall be disconnected.

12. The pressure gauge used for the test shall have a valid calibration certificate.

03.05.03 Leak Testing

Note that pneumatic leak testing is not considered pressure testing in this context and may be

carried out at a pressure not exceeding 10% of the design pressure.

03.06 Work Inside Large Machinery

03.06.01 General precautions

The following precautions apply to work inside large machinery such as diesel engines

(including crank case, scavenge receiver, exhaust receiver, air cooler space) and generators.

Whenever entering inside the machinery a back-up person shall be left outside the

machine. The back-up person shall not leave the site until all personnel having entered

the machinery are back and accounted for.

Before entering the person in charge shall check that starting and turning of the engine

is positively prevented, ie. start air valves are closed and locked.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


83

The Turning Gear shall be engaged, and the person in control of the turning gear shall

keep constant contact with the person(s) inside the machinery.

Note that in most cases, the confined space requirements will apply to work inside large

machinery. Please refer to chapter 01.09.

03.06.02 Work in the Crankcase

When entering the crankcase, stepping boards shall be used, even for short durations

of work.

If stepping boards cannot be used for practical reasons, a safety harness shall be used.

The condition of the stepping boards shall be checked before use, and faulty boards

replaced.

03.06.03 Work in the Exhaust Receiver

Operatives shall use safety harness when placing the staging ladder to gain access from

the gallery to the exhaust receiver.

When climbing the ladder, the safety lanyard shall be properly secured to a point above

the person before he starts climbing.

03.06.04 Work in the Scavenge Receiver

Under no circumstances, during port inspection or for other reasons, may a hand be inserted

into the cylinder from the scavenge space.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


84

03.06.05 Responsibility for Operating the Turning Gear

The use of the turning Gear shall be under the

responsibility of a nominated Turning Gear Key

holder. The key holder(s) are responsible that all

applicable safety precautions and procedures are

followed.

The turning Gear key holder may grant

permission to nominated Turning Gear operators

to operate the turning gear under their

supervision.

A list of nominated Turning Gear key holders and

operators shall be prepared and signed off before

the work commences.

The Turning Gear Procedure format is included in

Appendix.

03.07 Erection of Large Structures at Height

The mechanical erection works include erection of a number of large structures at height, such

as:

Exhaust silencers and associated ducting.

Exhaust gas boilers and associated steam vessels, ductwork and dampers.

Abatement units in the exhaust gas stream.

Chimney stacks.

Radiator Coolers

Engine hall ventilation systems.

While the general hazards are covered under the chapters for work at height, ‘common’ lifting

operations, use of forklift etc. the risks related to installation of heavy equipment shall be

assessed specifically, based on the actual weights, dimensions and weather (wind, rain, snow,

visibility etc.) conditions, crane limitation etc. BWSC Construction Department will cooperate

with BWSC Engineering in the production of detailed method statements and risk assessments.

04 Electrical Erection

This chapter covers the Electrical Erection activities up to the point of energizing. For all

activities associated with electrical systems or subsystems, after they are energized, please

refer to the Test & Commissioning in Chapter 5.

04.01 Electrical Erection Work in General Electrical Erection includes installation of the following:

Cable runways, typically ladder racks, cable trays and conduits

Elevated floor systems, typically in the Control Room and the LV/MV rooms

Step-up and auxiliary transformers

LV, MV and HV panels and switchgear

Pulling and termination of power cables and control cables

Battery banks

Light & Small power installations

Fire detection and alarm systems

Telephone systems

Computer network cabling

CCTV and PA systems

04.02 Particular safety hazards related to electrical erection

works

The safety hazards associated with the above activities are first and

foremost those related to working at height, lifting operations and

use of power tools. Working at height from scaffolding or mobile

elevated work platforms takes place throughout the erection period.

As the safety hazards and precautions related to these activities are

covered in Chapter 1 under Common Activities, no further

descriptions will be given here.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014

Cable pulling often involves working with heavy loads at places with restricted and difficult

access at considerable heights. Particular attention shall be given to the safe system of work

under these circumstances.

Typical cable ladder arrangement, suspended from ceiling. Illustration from BWSC Erection

Guidelines.

04.02 Acid filling of Batteries

In plants where acid filled batteries are

used for the battery system, a

considerable amount of acid is handled

during filling operations.

The filling shall take place in a well

ventilated room, and there shall be easy

access to Emergency Eye Wash station

and Emergency Shower.

Illustration from BWSC Erection Guidelines

During the acid filling of the batteries, a voltage will build up,

and the risk of electrical short circuiting or electric shock is a

potential hazard which shall be controlled. Only proper

insulated tools shall be used.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


88

When handling acid the following PPE is required:

Eye protection goggles type

Rubber gloves

Rubber boots

Rubber apron

Filling batteries is subject to separate Method Statement and Risk Assessment (COSHH

assessment).

04.04 Temporary Electrical Installations

04.04.01 Site Construction Power

Site construction power supply will be established during the initial site mobilization. Since the

BWSC Electrical Supervisor will not be on site at that point in time, the works shall be carried

out and supervised by external, fully qualified electricians. Often, this task will be included in

the Civil Contractor’s scope of work.

Applicable national safety rules for Electrical Work shall be observed.

The following precautions shall apply:

When BWSC’s Electrical Supervisor is mobilized, all temporary electrical installations

shall be subject to his approval.

Supply cabinets which form part of the system shall be locked.

Electrical hazard warning signs shall be displayed on supply units.

Only approved electrical plugs and extension cables shall be used.

Avoid routing extension cables through busy areas.

When possible, route the cables at height where it cannot be damaged or impose

tripping hazards or danger for persons working in the area.

Always make sure that proper earth and overvoltage protection is installed.

Temporary electrical installations shall be subject to frequent inspections. Cables with

damaged insulation shall be replaced or repaired; faulty plugs or sockets shall be

replaced.

The temporary installations shall be documented in a single line diagram, showing main point

of supply, switchboards, cabling and protection.

04.04.02 Mobile Generators

Diesel or petrol driven mobile gensets are frequently used on our

construction sites, either as local supply of power tools in areas where

general construction power is not available, or as site wide source of

construction power. The size of gensets commonly used varies from

portable units giving a few kVA to skid-mounted or containerized units

providing several hundred kVA.

The illustration on the left shows an example of a 250 KVA genset

which typically forms part of a more permanent site construction

power installation.

Generators are frequently hired from plant-hire companies which

in turn are responsible for providing the hirer with information for

the safe installation and use of their equipment.

BWSC Electrical Supervisor or other competent person shall always be consulted and involved

in the installation of mobile generators.

While the small size, portable gensets require no particular considerations, the larger

installations require a range of precautions as detailed in the following.

04.04.03 Mobile Generator Installation

Earthing and protection devices shall be installed as required. This depends on the type

and mode of operation and shall be determined by the plant-hire company or BWSC

Electrical Supervisor.

As the generators require frequent re-fuelling, a safe fuel handling arrangement shall

be in place. Apart from the internal tank, usually found in the base frame of the genset,

often the gensets will be connected to an external fuel tank through hoses and change-

over valves. The arrangement shall be installed so that the risk of fuel spill is

minimized. All valves shall be provided with padlocks to prevent use by un-authorized

persons.

It is a requirement that the fuelling operation is supervised at all times.

Easy and safe access shall be provided for fuel trucks and bowsers.

Exhaust fumes shall be able to escape away from working areas.

Heat generated by the generator shall be able to escape freely.

Noise hazards should be minimized. If the generator is not provided with its own noise

enclosure, other means of noise control shall be in place.

Fire extinguisher of correct type (powder ABE or foam) shall be available close to the

generator and any external fuel tanks.

Cables shall be routed such that they are not subject to damages or posing a hazard to

people working in the area.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


90

Mechanical protection shall be installed on main supply cables.

If feasible, the generator installation shall be enclosed by suitable temporary fencing

with access through a lockable gate.

04.04.04 Mobile Generator Operation and Maintenance

An authorised person shall be appointed to be in charge of the gen-set installation, including

the daily start and stop and re-fuelling. Do not allow any other person to operate or maintain

the generator and associated installation.

Generators are subject to planned maintenance and regular inspections are required. Always

follow the instruction provided in the manufacturer’s Operation & Maintenance Manual.

04.04.05 Temporary cables in S-hooks

Temporary cables shall be placed so that they do not get damaged or obstruct walkways and

stairs. They shall be hung from glass fibre safety hooks – so-called S-hooks as shown below:

Subject: 05 Testing and Commissioning

91

05 Testing and Commissioning Testing and commissioning includes the initial energizing of dead systems, as well as

subsequent work on systems previously energized.

The systems can be divided into mechanical systems and electrical systems, however due to

the nature of the work both mechanical and electrical safety hazards may be present at the

same time.

Test & Commissioning activities involve materials handling, lifting operations and work at

height, which are covered by Chapter 1, Common Activities. Reference is also made to

“Working in confined spaces” and “Work inside large machinery” covered in previous chapters.

This chapter will, therefore, deal exclusively with those activities which are specific to the test

and commissioning work activities and which are not covered elsewhere.

The chapter will give an introduction to the type of risks involved and appropriate controls to

avoid or mitigate those risks, including Permit to Work procedures. Specific Risk Assessments

shall be in place before undertaking work on energized systems.

05.01 Initial Energizing Before initial energizing of mechanical and electrical systems the T&C Manager will obtain

confirmation from the BWSC Erection Supervisors that installation of the equipment in question

has been fully completed. The confirmation will be reviewed with relevant P&I diagrams and

electrical diagrams and wiring lists.

Once the components and systems have been energised they will be clearly

marked with the appropriate warning signs.

When panels have been energized, the switchboard rooms will be considered

restricted areas where particular measures are enforced, doors are locked,

separate operator induction, signatures for authorization etc.

Doors are normally marked ‘Authorized and controlled access only’.

Work still require planning by means of the RAMS system.

05.02 Permit to Work Procedure

As a general rule, all work on equipment, which has already been energized, requires a Permit

to Work (PtW) to be issued by BWSC’s Authorised Person, typically the T&C Manager. This

includes the work of physically locking out the equipment. In cases where work ties into

jointly with the power station’s Authorised Person, typically the Shift Charge Engineer.

Likewise, cancellation of the Permit requires authorization from both parties.

The purpose of the formalised Permit to Work system is to describe the formal checks that

need to be undertaken such that all elements of a safe system of work are in place.

Specifically, the Permit to Work will ensure that the equipment upon which work is to be

performed has been clearly identified, de-energised, isolated and grounded as may be

necessary from any mechanical or electrical sources or inflow of energy or hazardous

substances, and that such sources have been locked out and tagged out.

At the time of handing-back, ie. re-instating and returning the equipment to service, the PtW

will ensure that all formal checks and procedures have been followed in the reverse sequence

before equipment is taken into use.

05.02.01 Issuing the Permit to Work

Please refer to the illustration page 92 (this section) showing the standard format for the

Permit to Work. The form is also included in Appendix.

The permit is issued by following these steps:

1. The Authorised Person (the permit issuer) will fill in Part 1 of the permit together with

the Person in Charge (the permit user). During this process, the equipment shall be

identified by specific references to P&I Diagrams, electrical diagrams or other relevant

documentation, the safety checklist shall be completed and any special instructions shall

be agreed, such as use of PPE.

2. Both the permit issuer and the user shall check and verify that the required mechanical

lock-out is in place and that the system is dead/non-pressurised. In case of electrical

systems, the checks shall include that proper earth is in place.

3. The Authorized Person will then sign Part 1 and the Person in Charge will sign Part 2.

05.02.02 Completion of the work - or cancelling the Permit to Work

After completion of the work or if the work has been suspended, the Person in Charge will sign

Part 3 of the permit. This will be acknowledged by the Authorised Person who signs Part 4.

The activities listed below shall be completed before the permit can be cancelled.

area or if multiple other entities want to secure the lock out area at same

time

05.04.02 Earthing Procedures

When HV plant and apparatus is to be discharged and earthed, it shall be done:

1. Where practicable by the use of a circuit breaker or specially provided earth switch.

When the circuit breaker is used, the trip feature shall be rendered inoperative before

closing unless this is impractical. After closing the circuit breaker or earth switch it shall

be locked in the earthed position.

2. Where above is not practicable, the HV plant or apparatus shall be tested to ensure that

it is switched off and will then be discharged and earthed by temporary earthing cables

applied by means of an insulated pole or other approved apparatus.

3. Earthing cables and associated clamps shall be of an approved type and of adequate

capacity and the minimum length for duty at the point of application. Minimum 70mm2

copper or 90 mm2 aluminium earth wire shall be used.

4. Earthing cables shall be properly maintained and always inspected just prior to use by

the Authorized Person.

05.04.03 Earthing and short-circuiting devices

05.04.04 Procedure for the use of Earthing Cables

1. Verify that the circuit is dead. Where practicable, test by means of a test-pin voltage

indicator of approved type. The indicator shall itself be tested immediately before and

after each use.

2. Earthing cables shall be connected to the earth system, which shall be solidly earthed

before being connected to the phases. They shall only be secured to the phases by

means of an insulated pole or other approved apparatus. Care shall be taken to ensure

that good contact is made, and that clamps are of adequate capacity for the potential

fault level.

Earthing and short-circuiting of electrical installation is a vital part of the

safety rules.

The figure shows an example of commonly used equipment for earthing

and short-circuiting



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


98

3. All phases shall be earthed and short circuited, even if work is to be carried out on one

phase only.

4. Earthing cables shall not be applied in any cell or compartment in which there is any

exposed live metal at High Voltage at all.

5. When earth cables are being removed, they shall be disconnected from the phases first

and the earth system last.

6. For the purpose of applying earth on spout contacts of metal clad switch-gear, only

approved appliances shall be used. Alternative, if no spout is installed, then make

earthing to the PE-Bar. The insertion of the hand or any tool into contact spouts for this

purpose is forbidden.

7. The spout will be checked by an approved test-pin, voltage indicator before the earth is

applied.

8. The indicator itself shall be tested before and after each application.

05.04.05 Safety Distance to Live Parts

The Safety Distance is defined as the necessary distance to avoid flash over from live parts.

Safety distance for non-authorized personnel is marked Distance Vicinity (DV)

Safety distance for authorized persons working on live parts is marked Distance Live

(DL)

Zone DL: Defined as the zone surrounding a live component, where the level of insulation

does not prevent accidental discharge.



Doc. no.: 6000.QH.001.001 Rev.: 2 Date: 18/02/2014


99

Zone DV: Defined as a safety zone, surrounding the DL zone. Any personnel in the DV zone

shall be AUS certified or working under instructions from certified personnel.

DV zone shall be clearly indicated by use of plastic chain, tape or barriers, and if deemed

necessary, the zone can be expanded, to ensure safety for all personnel.

The Safety Distances should always be determined in the following situations:

1. When inspecting non-embedded live high-voltage plant parts

2. When working close to non-embedded high-voltage plants, including establishment and

cancellation of safety precautions in connection with the work

3. When working on high-voltage components under voltage, special preparations, tools

Subject: 06 Steam Systems

105

06 Steam Systems

06.01 Steam system hazards Hazards in high pressure steam and water systems are mostly related to accidental escape of

steam or water due to failure of the pipe system, such as cracking, failure of gaskets/seals or

even pipe rupture.

Leaks in modern, high pressure piping are rare as both design and installation is thoroughly

controlled by international regulations.

06.01.03 High pressure steam or feed water pipe leakage

Feed water, boiler and turbine piping systems contain water or steam at very high pressures

and temperatures. In case of a leak of feed water it will evaporate almost instantaneously and

turn to superheated steam.

Note that superheated steam is invisible. Unless it cools down and forms a visible steam jet it

may only be detected by a hissing sound.

Smaller leaks of steam/water may cause fatal scalds, burns or cuts. Larger leaks may due to

the rapid expansion of steam suppress the air in the room and lead to suffocation.

If a leak is heard or detected personnel shall IMMEDIATELY locate the nearest exit, evacuate

the building and report the observation to the control room.

Repair is performed by specialist crews only.

06.02 Preventative measures Never perform work on or near a high pressure steam/water systems without proper working

permit and safeguarding of working environment.

Keep walkways, stairs and doors free of debris and equipment at all times to keep escape

routes free

Ensure escape routes are clearly marked and well illuminated.

Always familiarise yourself with the building and remember where your nearest exit is located.

106

Remember to do it safely – or not at all.

There is always time to do it right !
