4.0 CLOSE INTERVAL POTENTIAL SURVEY:
The Protective Potential measured at the test Stations gives an indication of corrosion protection
potentials at every one Km interval on the pipeline. To evaluate the exact state of polarized potentials
on pipeline at every one meter a Close Interval Potential Survey is to be carried along the pipeline. The
ON/OFF CIPL survey is recommended to be carried out on yearly basis to evaluate the corrosion
health of pipeline.
Generally CIPS is carried out with two different methods namely ON CIPS and OFF CIPS. The ON
CIPS reading gives us an overall indication of availability PSP of pipeline including the IR drop of soil.
The ON CIPS PSP value does not give the true polarized potentials and hence the reading are
misguiding as it contains the IR drop of Soil, which gets added into the measurements.
To evaluate the criteria of protection on pipeline it is required to eliminate the IR drop from the reading
to get ‘true potentials’ which gives the correct picture of state-of health of pipeline coating and forging
interference. To measure OFF PSP the impressed current from the CP Station is momentarily
interrupted and PSP is recorded in narrow band of time using computerized data logger. The polarized
potential gives you the true potentials developed on the pipeline surface to arrest corrosion thereby
generating a monomolecular layer of hydrogen.
The following CIPL Instrument shall be deployed for carrying out CIPL Survey.
CIPL Computerized Field Data Logger:
The “State of Art” microprocessor based Field Logger which can recorded data high speed of 0.05
Second and has a complete memory of 1,00,000 Reading. The Data Logger had programmable
recording rate, Hystersis, Trigger, Max-Min Recording Features and can be operated online with
Laptop Computer for online analysis of Readings.
The Software is latest windows based multi threading 32 bits multiple graphical presentation capability.
This shall give us detailed graphical representation output for ON and OFF PSP along with descriptors
along the Right of way.

1.0 SCOPE This specification covers the requirements for CAT & DCVG survey to be carried out for Cathodic
Protection System.
The cathodic Protection has to be provided to the Pipelines by either ICCP systems with T/R units and
Sacrificial anode system with Magnesium anode for achieving proper protection.
The objective of carrying out CAT & DCVG survey is primarily to ascertain the exact location and size of
all types of coating defects and secondarily is to find out the existence to any existing Interference. 2.0 CODES AND STANDARDS
The Basic Corrosion Survey shall be in accordance with the latest revisions of the following Indian
standards, wherever applicable. Where appropriate Indian standard are not available, the relevant IEC
standards shall apply.
a) Indian standards institution (ISI)
b) International electro technical commission (IEC)
c) American standards institution (ANSI)
d) British standards institution (BS)
3.0 Brief Scope of Work To locate the pipeline by pipe locator To find out the depth of the Pipeline from natural grade level. To plot a single line sketch of the P/L route with chainage and all obstacle crossings, ROW installation
and depth of the pipeline at every 100m. To ascertain exact location and magnitude of coating defect throughout the periphery of the pipeline. Bench marking of the defect location for relocation for coating repairing To establish the existence of interference situation, if any To verify the defect by excavating the pipeline To carry out coating repair at the defect locations To prepare the Detailed report of the entire survey work in tabulation as well as graphical form To summarize the total report along with interpretation and recommendations
4.0 Direct Current Voltage Gradient (DCVG) Survey:
4.1 Key set-up steps and procedures:
• DCVG equipment must have suitable ranges to at least 10 mV full-scale deflection.
• There must be adequate DCVG signal amplitude on the pipe, matched to the instrument's sensitivity. A 10-mV instrument will adequately work with a 50-mV DCVG signal. A 50-mV minimum range instrument requires a minimum DCVG signal of 200 mV.

• All instruments used on a survey must have equal sensitivity. The same instrument must be used for
all DCVG signal amplitude measurements.
• DCVG signal strength should be checked at test posts on either side of the pipe segment to be
surveyed to ensure adequate signal strength and confidence in the results. The measuring points
should be as close together as possible. The signal-strength measurements also are useful in planning
the CIPS.
• GPS coordinates for all features, such as test posts, fences, roads, valves and pig-signaler magnets
should be recorded, along with all DCVG locations, for later correlation and relocation.
• Place DCVG probes carefully to ensure that they are not too far apart. Make lateral checks every third
step to ensure the survey is on top of the pipeline. Look for the sausage-shape voltage profile, which
has a strong lateral gradient.
• If there are few defects, a pipe locator will be needed to prevent wandering from the pipe route. This is
particularly important when surveying pipe coated with two or three-layer extruded polyethylene.
• All signal amplitudes should be measured to remote earth, which will vary in distance from the pipeline
as a function of soil resistivity and amount of current flow to a defect. Remote earth typically is the
location where two DCVG signal readings, taken 6.0 ft apart, are similar, or very small.
• Temporary CP systems should be monitored to ensure they give constant current during the survey.
• Coating fault severity %IR values should be corrected for soil resistivity to a standard value, corrected
for depth of burial effects, and corrected for closeness to the T/R. PRIMAS software handles these
corrections.
• Complete DCVG data should be taken at each defect or test post to determine severity, corrosion
status and defect orientation.
• The DCVG survey should be conducted only in one direction to avoid confusion.
• The survey should start and finish at a test post each day.
• Comments relating to the survey, route and DCVG measurements should carefully be recorded for
future reference. At least two years can elapse between a survey and any excavation. Therefore,
detailed comments are useful for relocation purposes.

Safety committee is a key part of safety in the workplace. They shall accomplish the following::
a) Central focus : Overall look at safety requirements and to foresee problems that might otherwise cause difficulties.
b) Sounding board. The committee is a visible and approachable body for safety or environmental complaints, suggestions, and the like.
c) Central coordination. The coordination of safety training activities shall be accomplished by the safety committee.
An effective safety committee encourages safety awareness, gets a large number of employees actively involved in the safety program over time, helps motivate employees to follow sound safety practices. An effective employee safety structure provides a feedback mechanism to identify and correct new safety hazards at the earliest stage. Once the safety committee structure is in place and working well, it is a natural vehicle for employee involvement, preparation and introduction of new safety rules, new preventative practices, and safety procedures on new equipment.
Primarily safety committee shall look in to following: a) Detection of Hazard and determination of risks to workers, equipment,
property and environment. b) Deciding actions to mitigate risks c) Drawing Disaster Management Plan d) How the committee can help management to enforce safety rules and
environmental Impact mitigation measures. e) How to implement safety suggestions f) How to ensure compliance from workers.
Ideally safety committee members should play following roles:
a) Set a good example. Committee members must set a good example. They must be above average in their safe work habits and their positive attitude about safety and environment..
b) Be visible. Names of safety committee members should be posted prominently in their departments.
c) Conduct safety inspections. Safety committee members should perform safety inspections. Members know the safe—and the unsafe—way to perform the jobs. Hence, they are right men to correct unsafe situation.
d) Investigate accidents. Safety committee should investigates all lost work day accidents and record the findings.
e) Hold regular meetings. Safety committees must meet at least once a month,
83
and for their meetings to be effective the following matters must be considered:
Safety cum environment in-charge shall in general act as chairperson cum secretary
Preparing agenda & issuing in advance of the meeting to:
— keep discussions on track
— allow members to prepare for the meeting
Issuing Minutes within two days containing:
— written summary of proceedings
— names of attendees
— number of absentees
— responsibilities for implementation assigned
— timing of implementation assigned
— cost of implementation
— any approvals required
— completed recommendations
— uncompleted recommendations
— accident review (if any)
— safety training activities
Duties of Safety Committee members shall be as under:
• Work safely yourself—set the example in the site.
• Attend and actively participate in safety committee meetings.
• Speak to your fellow workers if you believe that they are engaged in an unsafe work practice; report things which you feel you can't handle.
• Listen to employee suggestions about safety and bring those that appear to have merit to the notice of safety committee.
• Before each safety committee meeting review minutes and open items affecting your section of job and have answers or a progress report on each item for the meeting.
Model code of practice for Safety Talks:
Safety talks should be delivered by any one of Safety Committee members by rotation. Duration could be anything depending on interest of audience and capacity of speaker to deliver oration. The speaker may like to use this opportunity to convey various decisions taken in Safety Committee to workers. He may prepare talk on following suggested topics or any topic of his choice but of relevance. Political or human relation related topic must not feature in Safety talks.

i) The site of the excavation or trench should be sloped or battered back to a safe angle of repose usually 45 degree or be supported with shoring by timbering or other suitable means to prevent collapse. The type of support necessary will depend on the type of excavation, type of soil, the nature of
90
ground and the ground water condition. Adequate timbering or sheeting shall be provided where excavation is deeper than 1.5 M. 100 mm wide “Safety tape” of yellow colour with one meter long phosphorescence band after every three meter shall be used to encircle excavated pit of any depth. For any pit of depth one meter or more, one meter high fence with a mid rail made of bamboo or steel pipes shall be provided for preventing people / animals from slipping into the pit. If the pit is by the side of vehicular drive way, in addition a prominent board shall be put up saying “Excavation in Progress”.
ii) Pumping out of accumulated water from pit is to be done at regular intervals. Run-away water shall be prevented from entering the excavated area, as such water can cause erosion of soil and sudden collapse of earth.
iii) If the excavation is carried out without shoring, necessary angle of repose shall be maintained at all times.
iv) Labourers shall not be allowed to sleep or take rest inside the pit. Protection against insects / poisonous snake shall be provided.
v) Excavated earth shall be stacked at least one meter away from cutting edge to avoid collapse of trench and sliding of heaped earth into trench.
vi) Contractor shall ensure that the excavation does not damage any existing underground cables, pipelines, foundation of adjoining buildings or structures etc. Wherever excavation is near any adjoining building or structure, proper precaution shall be taken.
vii) Before working / entering inside an existing excavated pit it shall be ensured that it is free from any toxic gasses or explosive gases. The underground water present in the pit shall be checked for acid content, if there is possibility of seepage of industrial affluent.
viii) Adequate access to and escape from the excavated trench in the form of ladders provided at every thirty meters or less shall be ensured. Crossovers over excavated trench shall be provided at suitable interval for movement of workers.
ix) If the excavated trench is adjacent to any parking space for vehicles, adequate and well-anchored stop blocks shall be provided on the surface to prevent vehicles from falling in to trench while reversing.
Relevant BIS codes shall be followed for safe practices.
26.2 PILING AND OTHER DEEP FOUNDATIONS
The following precautionary measures shall be taken:
• Piling machine operators shall be over 18 years of age and properly trained. • Prior to piling, all underground services shall be located and made safe • There shall be a firm level base for the crane. If necessary crane mats shall

Relevant BIS Safety Code for piling and deep foundations shall be followed. 26.3 WORKING IN BASEMENT / UNDERGROUND TANK .
Fatal and serious accidents could occur if proper precautions are not taken before entering confined space like basement or underground tank.. The following precautions shall be taken: i) Entry into the confined space shall be allowed only against Hot work permit. ii) Air circulation shall be ensured. Hot work in such places shall be taken up
only after ensuring that ample supply of fresh air is available using additional blowers etc. Proper ventilation shall be ensured by opening manholes (either ends if available) and fixing a wind sail or forced circulation of air. Old tanks shall be filled with water and washed with water before entering into it. Sludge shall be cleared / removed from outside of the confined space, to the extent possible, before entering.
iii) Workers shall be allowed entry in the confined space, only after ensuring absence of toxic and explosive gases. Purging of gases may be done by filling the underground confined space with water.
iv) Everyone inside the confined space shall wear rescue harness, with lifelines attached to a point outside the confined space. Whenever workmen are allowed to enter a vessel or underground tank or confined space, it is necessary to keep one person (alert and trained) at each manhole or entry point. The person should keep watch through manhole and offer rescue assistance so as to ensure prompt pulling out of the workers from confined space in case of emergency. Proper communication system between confined space and outside shall be maintained.
v) A proper procedure for rescue in an emergency shall be laid down, with specific duties allocated to specific persons.
vii) An experience supervisor shall supervise the entire operation. viii) Monitoring of air supply must continue while work in progress. ix) Only trained workers shall be allowed entry into confined space.. x) The following equipment shall be provided.: • Toxic gas meter, Oxygen meter and Explosive meter • Rescue harnesses with adequate length of rope taking into account the

• Demolition must be supervised by supervisor with thorough knowledge not only on demolition procedure, but also on the principles of structural construction.
• A survey of the physical characteristics and design of the structure to be demolished must be carried out in order to choose a safe method of demolishing. The demolition action plan shall be drawn by the contractor including drawings or sketches showing the sequence of operations, the machinery and equipment to be used, personal protective equipment required etc. Before demolition begins, all service connections to the structure shall be disconnected. Arrangements must be made to erect a fence of height two meter encircling the structure under demolition
• It is dangerous to leave isolated walls or parts of a wall standing alone, as those are liable to collapse from the effect of high winds and hence necessary supports should be given in such cases.
• Debris should not be allowed to build up against walls or floors with the consequent risk of the structure getting overloaded.
• Vapour present inside the structure must be checked for toxic nature before starting demolition work.
• Protective measures should be taken against dust, fumes, chemical deposits, asbestos, glass wool etc. while carrying out demolition work.
• Disposal process and pit / yard should be identified for safe disposal of debris.
• Relevant BIS safety code for demolition of structures shall be followed.
26.5 WORKING AT HEIGHT Scaffolds accidents occur primarily to the following reasons:
• Faulty design • Faulty erection • Weak foundation • Inadequate strength of structural members • Inadequacy of platforms, guard-rails and toe-boards.
Scaffolds are designed for live loads of workers and building materials, besides their own dead weight. However, a scaffold is usually designed only in case of important structures, like bridge girder/slab, very long beam/very large slab in buildings etc. In case of day today scaffoldings for general civil constructions / colour washing / painting / plastering etc., scaffolds are usually not designed, but erected based on experience. Scaffolds may be constructed of either timber, sal ballies, bamboo, or metal. Those may be single scaffold or double scaffold for light duty or heavy duty, as
93
the case may be. Single scaffolds are recommended for carpenter, painter and similar trade. Double scaffolds are recommended for masons and similar trade. All scaffolds should conform to IS:3696(Pt.1)-1987. As bamboo and metal scaffoldings are used, salient features of those scaffoldings are given below: Single Pole Bamboo Scaffolds : Single scaffold consists of one row of upright poles or standards, placed not more than 1.8mt centres, fixed at suitable distance from the wall and connected horizontally by ledgers (bamboo placed horizontally ) spaced vertically at 1.5 to 1.8mt centres. Cross members (putlogs), supported on ledger on one side and hole in the wall on other side, are provided at 1.2mt centres.
Double Pole Bamboo Scaffolds: It consist of two rows of up-rights or standards. The inner row is placed next to wall and other row placed 1.2 to1.5mt away from the wall. As in earlier case,ledger is provided every 1.5 to 1.8mt vertically. However, in this case , putlogs shall rest entirely on ledgers at both ends. Every single or double pole scaffolds, shall be effectively tied with adjacent structure. Diagonal face bracing or zig zag face bracing shall be provided on single pole scaffold and outer row of double pole scaffold. The maximum distance between braced bays in any lift of scaffold shall not exceed 10mt. Quality of Bamboo Bamboo should be reasonably straight, sound, free from splits, knots dry rot, worm holes and any other defect, which tend to reduce strength of bamboo. The mean diameter shall not be less than 80mm in case of single pole scaffold and 100mm in case of double pole scaffold, subject to minimum diameter of 50mm at thinner end. The slenderness ratio, i.e.L/d ratio shall not exceed 50, where L is the legnth of up-right or standard between putlogs. The diameter of bamboo shall not be measured at knot points.
Where it is necessary to extend a up-right, the overlapping distance between two up -rights shall not be less than 600mm. Maximum Height of Bamboo Scaffolds IS:3696(Pt 1) has recommended use of Bamboo Scaffolds for heights upto 18mt, subject to conforming to provisions given there-in. Platform Width for Working on Scaffolds � Where platform is not more than 2mt above ground or floor:
For Painters,Decorators etc 300mm (min) For other types ,i.e., mason etc. 500mm (min)
� Where platform is more than 2mt above ground floor:
For Painters,Decorators etc 900mm (min) For other types ,i.e., mason etc. 1200mm (min)
94
Railings & Toe Boards Railings consisting of top rail at a level of around 1000mm above platform and an intermediate rail halfway between top rail and platform shall be provided for all working platforms higher than 2mt above ground or floor. The platform edges shall be provided with 150mm high toe board to eliminate hazards of toolbar or other objects falling from platform. Where scaffolds are erected over areas, where people work or pass, the space between top rail and toe board shall be enclosed by tarpaulin or PVC sheets. Means of Access A safe and convenient means of access shall be provided to all platform level of scaffolds. Conventional means of access are the following: • Ladder • Stairway • Ramp
Ladder: • To ensure safe use of ladder, the following steps should be followed: • Erecting ladders in the "four up-one out position" (i.e 75 degree angle
between ladder and ground) • Lashing ladder securely with the structure. • Using non-slip devices, such as, rubber shoes or pointed steel ferrules at the
ladder foot, rubber wheels at ladder top, fixing woollen battens, cleats etc. • When ladder is used for climbing over a platform, the ladder must be or
sufficient length, to extend at least one meter above the platform, when erected against the platform in "four up-one out position".
• Portable ladders shall be used for flights not more than 4mt. Above 4mt flights, fixed ladders shall be provided with at least 600 mm landings at every 6mt or less.
• The width of ladder shall not be less than 300mm and rungs shall be spaced not more than 300mm.
Stairway For scaffolds exceeding 4mt height, stairway are safest means of access.
I t shall conform to the following: • Treads and risers shall be of uniform width and height in any one flight. • Minimum width of 1000mm. • No unbroken vertical rise of more than 4mt. • Maximum angle of ascent 50 degrees. • Stair railings on all open sides. • Hand rails on all enclosed sides. • Railings and toe boards on all landings.

is 1.5mt or more above ground or floor. • Where slope is more than 1 in 4, footholds shall be provided by stepping laths
of minimum size 50 x 30mm at interclass not exceeding 450mm. • Maximum permissible slope is 2 in 3.
95
Metal Scaffolds With the evolution of concept of designing multi -storied and long span structures, metal scaffolds came into practice, mainly due to following advantages. • Ease of assessing strength of scaffolds structure. • Reusable many more times than bamboo. • Possibility of human error while erection, is much less that in case of bamboo
scaffolding. • Aesthetically neat and good looking.
Metal scaffolds shall conform to IS:2750 - 1964, in addition to IS3696(Pt 1). Scaffold tubes are usually 40mm N.B., mild still continuous weld conforming to IS:1239 or IS1161, grade YST 210, of lengths varying between 4.5mt to 6mt. These are manufactured and marketed by various agencies. As such, it is essential to obtain guaruntee certificate from the manufacturer about safety and stability of metal scaffolds under likely worst combination of loads.
Other General Safety Requirements for all types of Scaffolds • Erection, alteration and removal shall be done under supervision of
experienced personnel. • Use of barrels, boxes, loose bricks etc., for supporting platform shall not be
permitted. • Every platform and means of access shall be kept free from obstruction. • Each supporting member shall be securely fastened and braced • Where planks are butt-joined, two parallel putlogs shall be used, not more
than 100mm apart, to give support to each plank. • Platform plank shall not project beyond its end support to a distance
exceeding four times the thickness of plank, unless it is effectively secured to prevent tipping. Cantilever planks shall be avoided.
• If Grease, mud, gravel, mortar etc., fall on platform or scaffolds, these shall be removed immediately to avoid slipping.
• Workers shall not be allowed to work on scaffolds during storms or high wind. After heavy rain or storms scaffolds shall be inspected by site-in-charge before reuse.
• All scaffolds or platforms shall be fastened with adjacent structure, and if independent, scaffolds shall be braced properly.
• Scaffolding shall be erected on firm and level ground. In case of loose soil, the soil should be compacted by watering and ramming, besides using wooden base plate of minimum thickness 30mm for erecting standards.
• All members of metal scaffolding shall be checked periodically to screen out defective /rusted members. All joints should be properly lubricated for easy tightening.
• Clear access to scaffolds shall be maintained at all times. For prohibiting entry of unauthorised persons in scaffolds area, barricades should be put up and warning notices prominently displayed.
• If scaffolds are used, where public movement is anticipated, entry of public should be prohibited for the duration of the job.
• Where lifts are provided to hoist premixed concrete, reinforcement etc., to upper floors, barricades should be raised to prevent accidental entry of
96
workers under the lift. Such lifts shall not be used for hoisting people, unless those are designed specifically for that purpose.
• Dismantling of scaffoldings shall be done in a pre-planned, sequential manner in order to maintain stability throughout the process. If necessary, additional tying, bracing may have to be done to prevent sudden collapse of scaffolds structure.
• Before initiating dismantling process, precautions should be taken to ensure removal of all loose materials from the scaffolds.
• Use of scaffolds, under dismantling process, must be prohibited. • Wearing safety helmets shall be made mandatory within 10mt from scaffolds.
Dismantling of Form -work Action for dismantling form-work, used for supporting concrete casting, must be done after expiry of requisite number of days after casting and proper curing. Untimely dismantling of form-work may cause total collapseof structure. Bottom shuttering of chajia or sun-shed should not be removed, till the attached lintel is properly secured by brickwork, to avoid failure of lintal due to toppling / torque. In case of casting of multi-storied framed structure, casting of upper floor should be avoided till expiry of minimum curing period of lower floor. But, if essential, bottom shuttering of the lower floor shall be suitably strengthened by additional props.
INDUSTRIAL SAFETY BELTS & HARNESSES Primary functions of safety belt & harness are to minimise injury after a fall. Despite providing proper scaffolds, railing etc, possibility of slipping and falling can not be over-ruled. This equipment is the last check to prevent worker from getting fatal injury.
Four types of safety belts & hareness are available in the market, depending on nature of various jobs. Failure to choose right type of safety belt & harness may led to endangering life of worker at the time of need. All safety belts and harness shall conform to IS3521-1989.
Type Consists of Permissible fall Used for
I Waist belt with safety line
Not more than 0.6mt
Building / Structural maintenance.
II Waist belt with two shoulder straps & safety line
Not more than 1.8mt.
Construction, structural erection.
III
Waist belt with two hoisting straps & safety line, with provision for leg straps.
Not more than 0.6mt.
Working in confined atmosphere and rescuing.
IV Waist belt with pole strap.
- Working on electric line pole.
Proper choice of anchoring point for anchoring the safety-line is essential. At many instances, the workers have met with fatal accidents due to anchoring with
97
weak supports. Sometimes anchoring points are found to be chosen by mistake in such a way, that should a person fall, he would hit against a rigid structure due to swinging action of the safety line. Hence anchoring point for safety-line needs to be judiciously chosen. Where proper anchoring points are not likely to be available, action should be taken in advance to provide for hooks and fixtures.
The shock absorbing capacity of the safety-line is critical for reducing impact of fall. A stiff safety-line, would arrest a fall suddenly, resulting in an abnormal impact load on body of the worker, causing injury. According to IS3521, safety-line should be made of nylon or polyester or synthetic fibre. It shall not break under minimum tensile load of 2000kg. The minimum diameter of test specimen shall be 10mm. Performance test of the Safety belt & Harness shall be carried out as per annexure - B of IS3521, by dropping an articulated anthropometric dummy weighing 100+5 kg with an overall height of 1.6mt to 1.8mt, and waist not more than 1000mm circumference.
INDUSTRIAL SAFETY NETS Industrial Safety Nets are designed to catch workers and / or debris falling whilst working on high buildings or structural fabrications. The safety net should be installed as close to the work level as possible. Sufficient clearance should be maintained between the safety net and the ground or structure below, in order to accommodate full deflection of the net under impact. IS 11057-1984 specifies requirements for two types of safety nets.
Suitable for use at maximum duty height (*) upto 6mt Suitable for use at maximum duty height (*)upto 1mt
(* The maximum vertical distance between working level and the level at which safety net is to be placed in use.) • Salient features are as under: • Minimum nominal size shall be 4mtX 3mt. • Shall be made with square or diamond mesh and the length of mesh side
shall not be more than 100mm. • In cae of multi layer nets, all layers shall be joined together and fitted to a
common border cord or cords. • A continuous length of net, with no joints shall be used. • When in use (without any load,except dead weight of the net), the sag at
centre of the net shall be between one-fifth and one-fourth of the length of the shorter side.
• Performance shall be tested by actual drop test of a sand bag weighing 140kg, in accordance with appendix A of IS-11057-1984.(Safety nets are available with an overlay net to catch small tools and debris. But, the performance test shall be carried out only after removing such overlay net.)
• The deflection at the centre of the net during above drop test, shall not exceed 2mt or one-half of the length of the shortest side, whichever is more.
• Manufacturer shall declare the duty height at which net conforms to IS11057 by fixing labels marked with indelible ink at two different positions on the net.

33 PIPELINE CONSTRUCTION SAFE PRACTICES
I. Handling and storage of pipes
a) Bare Pipes
* Unloading, loading, stockpiling and transportation of bare pipes should be done using suitable means and in a manner to avoid denting, flattering or other damages to pipes
* Pipes should not be allowed to drop but should be lifted or lowered from one level to another by suitable equipment
* Lifting hooks when used, should be equipped with a plate curved to fit the curvature of the pipe
* Pipe when stockpiled, should be placed on a suitable skid to keep it clear of the ground.
* The stacks must be properly secured against sliding and should consist of pipes of the same diameter and wall thickness
* Personal Protective Equipment like safety shoe and glove should be used by worker while handling pipes.
b) Coated Pipes
* Coated pipe shall be handled by means of slings and belts of proper width made of non-metallic/ non-adhesive materials
* Belts/slings when used should be cleaned to remove hard materials such as stone, gravel etc.
* Coated pipes should not be bumped against any other pipe or any other objects
* Rolling, skidding or dragging of coated pipes should be strictly avoided
* Coated pipes at all times should be stacked completely clear from the ground so that the bottom row of pipes remains free from any ground contact. Pipelines should be stacked at a slope so that during rain, water does not collect inside the pipe.
111
* The coated pipes may be stacked by placing them on ridges of sand and covered with a plastic film.
* Stacks should consist of limited number of layers so that the pressure exercised by the pipe's own weight does not cause damages to the coating
* The weld lead of pipes should be positioned in such a manner so as not to touch adjacent pipes
* Coated pipes stacked in open storage yard should be suitably covered on top to decrease direct exposure to sunlight
* The ends of the pipes during handling and stacking should always be protected with end protectors
II. Swabbing and Night capping
To ensure that all dirt and objects likely to cause obstruction in the interior of the pipe are removed, each length of pipe should be thoroughly scrabbled prior to alignment and welding. At the end of each day's work a steel plate or nightcap should be adequately secured over open ends of incomplete section of the pipeline to prevent ingress of extraneous objects and ground or floodwater. .
III. Inspection of field welds
In case of cross-country pipeline and where specifically specified, all weld joints should be radiographed to ensure the soundness of welding joints to avoid failure of joints, which may create serious pollution or environmental problem.
IV Coating Inspection in the field
Where pipeline coating is carried out in the field, all bare and primed pipe should be kept free from dust and grease, oil etc. Before the pipeline is lowered into the trench the coating should be thoroughly inspected both visually and by using holiday detector. Any visible damage should be repaired and the pipeline shall be retested.
V. Lowering and Backfilling
Equipment used for lowering the pipeline from the skids and positioning it finally in the trench should be sufficiently padded at points of contact with the pipe to prevent damage to the protective coating
* Slings used for lowering the pipe should be made of canvas or equally non-abrasive material and of a width not less than the diameter of the pipe.
* The trench should be clear of loose rocks, lumps or other objects that might prevent the coated pipe from bearing evenly on the trench bottom.
112
* When digging soil from beneath the pipe in order to remove slings, care should be taken to avoid damage to the protective coating. The coating should subsequently be inspected and any damage shall be repaired.
* In waterlogged areas it may be necessary to provide additional weighting or screw anchors to prevent floatation of pipeline.
* No lowering should be done after sunset without proper lighting arrangement
* Minimum 3 side booms should be used and mounting of counter weights should be ensured on side booms for lowering the pipes.
VI. Road, Rail and Water Crossing
* Where work being done either adjacent to or any public or private road; warning signs and night time warning lights should be provided and maintained.
* Crossing will frequently necessitate laying the pipeline at greater depth than normal and may therefore call for special measure to support the trench or boring pit.
* Where crossings are made by open cut, the work should be programmed so as to minimise the amount of time that the normal traffic or flow is interrupted. Where necessary temporary conduits or pumping system should be provided to maintain the flow in water courses
VII. Trenching
* Barricading should be made while trenching in heavy traffic area. * Sign boards should be provided while trenching in heavy traffic area * Trench cross over shall be provided at every 30 Mts. of its length while
trenching * Lighting should be provided for night working * Shoring should be provided for trench support * Underground service connections should be identified and marked
prominently * Excavation tools should be properly insulated to avoid electric shocks * Evacuation of workers should be ensured before blasting * Entry of workers in site, where blasting is planned to be done, should be
allowed after inspection and clearance from qualified Blaster • Requirements of safe procedure as stipulated in BIS Code IS:4081-1986
for blasting and drilling must be observed during blasting operation.
VIII. Pipeline Marks Distinctive markers should be created at all crossings to indicate the alignment of
the pipeline and should give information about ownership, diameter, the nature of content, the normal direction of flow and the location of the crossing. A telephone number for use in emergencies shall also be displayed.

35 CLASSIFICATION & WORKING IN HAZARDOUS ZONES Hazardous (flammable atmosphere) zones are classified as zone-O, zone-1 and
zone- 2. All other areas are unclassified but not necessarily non-hazardous. In these areas, safety precautions must be observed in order to eliminate risk of explosion. Zone-O is defined as the vapour space in and directly around product storage tanks. Zone-1 is defined as an area where vapours, may be expected at all times. For zone 2, flammable vapours may be expected to be presently when a failure to equipment or plant occur. Unclassified areas cannot be assumed to be always non-hazardous, therefore must be checked prior to issue of work permits, Following precautions shall be taken while working in hazardous areas.
35.1 NON-SPARKING EQUIPMENT Sparks can be produced from electrical tools/devices, and where two surfaces
collide. In order to avoid risk of sparking, only tools approved for use in hazardous zone-1 shall be used. The condition of all equipments used within hazardous zones shall be checked by BPCL Engineer. Where chipping or scraping is necessary in a hazardous area, several precautions shall be taken such as; the surface being chipped or scraped shall be kept moist with water at all times ; Air driven jackhammers may be used where atmosphere has been certified to be safe and the impacting surfaces must be submerged in water.
35.2 CHECKING OF WORKERS
Workers are to be checked for matchboxes, lighters and other spark producing items. If workers are found to be carrying any such item, the same shall be taken into custody by security at the entry point.
114
35.3 SAFETY CHECKS
In all cases where work is to be carried out within hazardous zones, BPCL Engineer shall check the area using an explosimeter for the presence of flammable vapours. The explosimeter shall be verified before each use, for its smooth functioning. Should there be any indication of flammable vapours, steps shall be taken to reduce the vapour content of the surrounding atmosphere. If found safe after re-checking by explosimeter, the work permit shall be issued.
35.4 FIRE SCREEN WALL
Fire screen shall be provided to segregate area where hot works, such as welding & cutting, is planned to be done from surrounding. To construct fire screen, the following shall be complied with:
• Members shall be made of appropriate size MS pipes, MS structurals, strong enough to withstand the wind, live and dead loads. The bottom of columns shall be properly grouted.
• Good quality G.I. Sheets free from damage and holes shall be used as screening wall. G.I. Sheets shall be properly tied up with the structure.
• The height of fire screen wall shall be decided based on the level at which hot work is supposed to be carried out. For example, in case of above ground tanks fabrication by jacking up method, a fire screen of 6 M height is sufficient where as in the other case it is required to have a height equal to height of structure to be fabricated.
36. WORK PERMIT SYSTEM
If work is to be performed in a hazardous area, a duly authorized written work permit shall be obtained by the contractor from BPCL or any official duly authorized by BPCL for this purpose. This is a document authorizing contractor to carry out the work concerned, warning him of the possible hazards and spelling out precautions needed for the job to be done safely. The contractor shall be fully aware of the details of the work permit system and shall obtain the same signed by authorized person before starting the job. Based on the nature, the work shall be undertaken either under Cold Work Permit or Hot work / Entry to confined space permit or Electrical isolation and energisation permit.
Permits and certificates are to be issued by BPCL Engineer or any official duly authorized by BPCLfor this purpose with overall responsibility for the work area.
All work permits shall carry serially printed numbers. The printing of all work permits shall be done by the contractor in adequate quantity at his own cost.
36.1 COLD WORK PERMIT:

36.2 HOT WORK / ENTRY TO CONFINED SPACE PERMIT:
All hot work such as welding, grinding. gas cutting, burning, shot blasting. soldering, chipping, excavation, open fire, use of certain non-explosion proof equipment etc. shall be carried out through Hot Work Permit. Entry and operation of petrol or diesel driven vehicles or equipment without spark arrester in hazardous area also falls in the category of hot work, and shall be performed under the hot work permit.
The confined space entry permit is required for the protection of personnel entering a confined space such as Vessels, boilers, storage tanks, large diameter piping etc against hazards such as oxygen deficiency, toxic and flammable materials, falling objects, power driven equipment etc. Excavation more than 1.2 meter deep, entry on floating roof tank when the roof is more than 3 meter down from the top, space located below ground level such as pits, drain, channels etc. also fall under the confined space.
For excavation work regardless of the depth, permission from various sections
shall be obtained with precautions to be taken for the underground facilities viz; sewers, telephone lines, cables, pipelines etc.
This work permit shall be in minimum three copies. The original should be in pink
colour and copies should have the word "COPY" printed in large pink letters. Original shall be issued to the contractor, duplicate to the Safety Section and triplicate retained in the book. (Ref. Annexure-II)
36.3 ELECTRICAL ISOLATION AND ENERGISATION PERMIT Before issuing any work permit, it is essential that the equipment / facility to be
worked on is electrically safe and electrical power is isolated to the extent necessary for the safe conduct of the authorized work.. Permit for electrical isolation and energisation shall be in triplicate and in two sections with tear off facility. Section-A shall be used for electrical isolation and Section-B for energisation.

37. ACCIDENT REPORTING AND CLASSIFICATION
37.1 ACCIDENT REPORTING
All employees must be encouraged to report any near miss incident that has or could have caused injury, illness, damage to property, or interruption in work. The reporting of such incident helps in analyzing what went wrong and enables steps to be taken to prevent recurrence. The accident reporting forms the basis for objective investigation of the accident and will bring out essential and contributory factors leading to It. The necessary decisions then can be taken to prevent recurrence in future.
37.2 CLASSIFICATION OF ACCIDENTS
Accidents are classified as follows:
a) Near Miss
It is a 'narrow escape' where accident, major loss or injury did not occur. Such incidents must be reported locally and the working conditions leading to it must be investigated.
b) Fatality
A death resulting from work injury is covered under this category irrespective of the intervening time between injury and death.
c) Permanent total disability
Personal injury which incapacitate a person completely and results in termination of employment.
d) Permanent partial Disability
Any injury which results in complete loss or permanent loss of use of any part of body or any permanent impairment of the function of the body.
e) Lost Work-Day Case
Any injury excepting permanent partial disability which renders the injured person unable to perform any regular job on any day after the day of receiving the injury.
117
f) Restricted work case
After the injury, the injured person can not perform his normal duties or regular job.
g) Lost work days
The number of calendar days on which the injured person was temporarily unable to work.
h) Restricted Work days
The total number of calendar days from the start of Restricted work, by the injured persons, till he returns to his regular job.
i) Medical treatment cases
The injury requiring medical treatment under order from a physician but does not involve Lost work Days, or restricted workdays.
37.3 REPORTING
Contractor shall notify BPCL as under:
Lost time injuries / Fatality / Injury which may cause total or partial disability to
injured etc -immediately.
Fire and Miscellaneous Events- immediately.
First Aid injuries-Within a day.
38 SAFETY TRAINING
Training is a pro-active measure. The contractor shall engage only those workers who are proficient in their respective jobs. It is responsibility of contractor to impart job knowledge to all workers and supervisors before engaging them for any work. It is also binding to the contractor to depute persons for safety training, if arranged by BPCL.
39 DOCUMENTATION Following documents shall be maintained by contractor at site:
� Safety & Environment Policy � Safety committee minutes of meeting � Critical machinery/equipment fitness certificate. � Stock register of Personnel Protective Equipment. � Maintenance registers for major machineries/equipment.
118
� Accident / incident investigation reports. � Various work permits. � Earthing test certificates. � Materials test certificates. � P.F., Contract Labour, ESI registration. � All records & registers as required under Contract Labour (Regulation &
Abolition Act) 1970 and Building & Other Construction Workers Act 1996.
40 ENVIRONMENT PROTECTION
Contractor should ensure that the work carried out by him does not change the quality of air, water & soil at the work site & surrounding areas. Disposal of surplus earth, rubbish, scrap etc. shall be done in Eco-friendly manner. The contractor shall ensure that the greenery is protected to the extent possible while executing the work.
41 ENVIRONMENTAL IMPACT MITIGATION MEASURES
The best way of impact mitigation is to prevent the event occurring. All efforts should be made to locate the developmental activities in a area free of agricultural lands, cyclones, earthquakes, ecologically sensitive, erosion, forests, flooding, human settlements, land slides, natural scenic beauty, water logging. In case this is not feasible, the next step is to look at the raw materials/technologies/processes alternatives which produce least impact i.e. adopting or using processes or technologies which are efficient and produce recyclable wastes/minimum waste/wastes that can be easily disposed, without affecting the environment. However if the developmental activity produce the adverse impact, action has to be taken to mitigate the same. Following are the suggested methods, which shall be taken in to consideration by the contractor to choose right technology for executing the work:
41.1 AIR
• Attenuation of pollution on pathway or protection of receptor through green belts.
• Particulate removal devices such as : cyclones, setting chambers, scrubbers, electrostatic precipitators, and bag houses.
• Gas removal devices using absorption (liquid as a media), adsorption (molecular sieve), and catalytic converters.
• Uses of protected, controlled environment, such as oxygen masks, Houston Astrodome, etc.
• Control of stationary source emission (including evaporation incineration, absorption, condensation and material substitution)
• Use of masks • Dilution of odourant (dilution can change the nature as well as strength of an
odour) • Odour counteraction or neutralize (certain pairs of odours in appropriate
concentration may neutralize each other)
119
• Odour masking or blanketing (certain weaker malodours may be suppressed by a considerably stronger good odour)
41.2 NOISE
• The mitigation measure may include damping, absorption, dissipation and deflection methods. Common technique involve constructing sound enclosures, applying mufflers, mounting noise sources on isolators, and/or using materials with damping properties.
• Performance specifications for noise represent a way to insure the procured item is controlled.
• Ear protective devices should be used. When an individual is exposed to steady noise levels above 85-dB (A), in spite of the efforts made to reduce noise level at the source, hearing conservation measures should be initiated.
41.3 WATER
• Conjunctive use of ground/surface water, to prevent flooding/water logging/depletion of water resources. Included are land use pattern, land filling, lagoon/reservoir/garland canal construction and rainwater harvesting and pumping rate.
• Minimize flow variation from the mean flow. • Segregation of different types of wastes. • Storing of oil wastes in lagoons should be minimized in order to avoid
possible contamination of the ground water system. • Surface runoff from oil handling areas should be treated for oil separation
before discharge into the environment. If oil wastes are combined with sanitary sewage, oil separation will be necessary at the waste water treatment facility.
• All effluents containing acid/alkali/organic/toxic wastes should be processed by treatment methods. The treatment methods may include biological or chemical processes. The oil water separator of appropriate size based on catchment area shall be provided.
• The impact due to suspended solids may be minimized by controlling discharge of wastes that contain suspended solids; this includes sanitary sewage and industrial wastes. Also, all activity that increases erosion or contributes nutrients to water (thus stimulating alga growth) should be minimized.
• Waste-containing radioactivity should be treated separately by means of dewatering procedures and solids or brine should be disposed of with special care.
41.4 LAND
• The environmental impact of soil erosion can best be mitigated by removing vegetative cover only from the specific site on which construction is to take place and by disturbing the vegetation in adjacent areas as little as possible. Land clearing activities should be kept to the absolute minimum.
120
• Disturbing the existing vegetation and natural contour of the land as little as possible can mitigate increases in surface runoff. Vegetation along watercourses should not be cleared indiscriminately. Neither should potholes or swamps be drained unless absolutely necessary for successful completion of the activity.
• Construction activities that result in the soil being laid bare could be scheduled in such a way that some type of vegetative cover appropriate to the site could be established prior to the onset of intense rain or windstorms. If grass is to be seeded, mulch of straw will help to protect the soil from less extreme erosive forces until vegetative and root development begins.
• Natural drainage patterns can often be maintained by preparing sodden waterways or installing culverts.
• Steep slopes can be terraced, thereby effectively reducing the length of slope.
• Check dams built near construction sites can reduce the quantity of eroded soil particles reaching free-flowing streams or lakes.
• Use of “floating” foundations and height restrictions in earthquake zones and increased foundation height, wall strength and roof support in areas periodically subject to cyclones can reduce the hazards.
• All forms of temporary structures should be avoided from the flood plain and all permanent structures should be raised to a height above the level which flood waters can be expected to reach once very 100 years (100-year flood).
• Installation of underground drainage structures helps to reduce sediment loads.
• Engineering plans can be drawn to reduce the area of earth cuts on fills below what might otherwise be acceptable, provide physical support for exposed soil or rock faces, concentrate or distribute-as appropriate the weight loading of foundations to areas or state better able to support that weight.
• Use small charges for mining/blasting. • Restricting the number, frequency and area of movement of heavy
machinery. • Compatibility between adjacent land uses can best be assured by providing a
green belt between the proposed activity and nearby properties where any significant degree of incompatibility is likely to result.
41.5 ECOLOGY
• Intruding as little as possible on their habitat can best mitigate the impact of activities on animals. If such animals use the area where the activity will take place, the activity should be concentrated to the maximum extent possible in those parts of the area that they least often frequent.
• During the planning phase of an activity, an attempt should be made to avoid extending into the home range wild animals. If this is not feasible, the activity should be completed, as quickly as possible, and regular and sustained use of the area over time should be minimized.
• Regular or sustained intrusions of men or equipment into nesting areas of birds should be avoided to the maximum possible extent, especially while are being incubated by the adults and until the young have left the nest. The
121
sanitation cuttings of non-commercial individual trees should destroy no known nests.
• Restricting the input of polluting substances into watercourse, estuaries and the open sea can mitigate impacts upon fish and shellfish populations. Additionally, when a part of the activity involves water level control, changes in such levels should be programmed to be extent, it is possible to do so in a way that will minimally disturb nesting and feeding habitat.
