Permit To Work Manual

FOREWARD Operating our business safely is CS Energy’s highest priority. We genuinely care about the health and safety of our employees and contractors who undertake maintenance and refurbishment task at our sites. We also recognise that completion of the tasks in a safe, timely and quality manner is the foundation for ensuring that CS Energy continues to generate electricity safely, reliably and economically. To achieve this, we use the Permit to Work System (PTW) to provide all workers safe access to plant and equipment. The PTW System is considered our primary safety system and is used widely across CS Energy’s sites. The PTW System ensures a high level of control and minimisation of risk in areas that contain energy. CS Energy’s PTW system has been developed to comply with the Generator’s Permit to Work Code of Practice. This Manual outlines the key elements of this system such as roles and responsibilities, procedures, training, reporting and monitoring activities. Copies of this company-wide manual are available at each CS Energy site. It is also included on the company’s intranet, where additional supporting documentation, such as our hazard control procedures, isolation procedures, standard operating procedures, is also held. I encourage you to familiarise yourself with this Manual. Only with the dedication of every person on every CS energy site, can we achieve our goal of zero harm. Brian Green Chief Executive

1 PURPOSE

The purpose of this Permit to Work Manual, (the Manual), is to provide structure and process on the Permit to Work (PTW) System. The objective of the PTW System is to:

• Control the access to plant and equipment • Minimise the risk of injury to personnel • Minimise the risk of damage to plant • Comply with the Workplace Health & Safety and Electrical Safety Legislation • Comply with the Queensland Electricity Generators Permit To Work Code of Practice.

The PTW Manual defines specific authorisations and responsibilities to establish a standard and consistent process for all PTW activities.

2 SCOPE

The PTW Manual is applicable to all work being undertaken at CS Energy sites. It describes the provisions of the PTW process, framework of the PTW system and PTW suite of documents that support the system. The PTW manual does not apply to:

• Plant that has been de-commissioned – removed existing energies; • Plant that is not yet a CS Energy asset; • Plant that is being commissioned for CS Energy where CS Energy is not the Principal Contractor (i.e.

not yet ‘handed over’ to CS Energy).; and • CS Energy First/Emergency Response Teams or Emergency Services when executing a rescue

during an emergency or crisis. Figure 2.1 PTW System Documentation Hierarchy

6 PTW PROCESS

NOTE: a number of processes external of the PTW process are required to be completed before the application of the PTW can be requested. These processes are included in Figure 6.1 for reference only and are not considered to be incorporated into the PTW process. The application of the PTW System incorporates 8 key elements to complete the process. The 8 Elements include:

• Application for PTW (APTW) • Drafting Isolation sheet/Work Clearance Document (WCD) • Plant Isolation • PTW/Work Clearance Application (WCA) Issue • Performing Work • PTW Suspension (where required) • PTW Surrender • Restoration of Plant

Each element requires key roles and responsibilities to effectively and safely apply the PTW process. Refer to Figure 6.1 (below) which details the process flow of the life of a PTW.

6.1 PTW Lifecycle

Figure 6.1 outlines the elements of the PTW process. The diagram below provides the process for a ‘standard’ PTW. The elements required for a PTW is subject to variation.

8.3 Draft Isolation Sheet

Drafting the isolation sheet for Isolating LV and HV single supply equipment for the purposes of mechanical isolation requires a PTWO to draft and second PTWO/SPTWO to check the isolation process as specified in the scope of work. The isolation sheet shall incorporate an isolation or set of isolations that suitably eliminates all energy sources for the work to be done. Refer to CS-PTW-ISO-01 Safe Mechanical Isolation (Draft only) and CS-OHS-53 High Voltage Isolation and Access for instruction on effective isolation.

Note: Isolation of plant that contains multiple High Voltage (HV) and Low Voltage (LV) electrical feeds requires the use of switching sheets. The switching process has specific business and legislative requirements that shall be adopted (e.g. authorised electrical personnel, mandatory checks, etc.). Refer to CS-PTW-SOP-02 Training and Authorisation in the PTW System and CS-OHS-53 High Voltage Isolation and Access.

• check and confirm the isolation sheet is accurate for scope of work and mark it ‘prepared’ in SAP

8.4 Isolating the Plant

The PTWO/isolation officer for the PTW must isolate the plant using a red isolation lock and Danger tag as specified in the isolation sheet. Refer to CS-PTW-ISO-01 Safe Mechanical Isolation and CS-OHS-53 High Voltage Isolation and Access for instruction on effective isolation. A second person (OIC or other PTWO) shall confirm the isolations correspond with the isolation sheet.

Note: Isolation of plant that contains multiple High Voltage (HV) and/or Low Voltage (LV) electrical feeds requires the use of switching sheets. The switching process has specific business and legislative requirements that shall be adopted (e.g. authorised electrical personnel, mandatory checks, etc.). Refer to CS-PTW-SOP-02 Training and Authorisation in the PTW System and CS-OHS-53 High Voltage Isolation and Access.

Figure 8.3 Isolating the Plant

• stop isolation process when the plant identification process does not match the corresponding items in the isolation sheet. Follow site process to rectify.

• initial each isolation step on the isolation sheet as it is completed • electronically record the isolation steps completed in SAP • secure the red Isolation Key/s with a green PTWO Lock at the Isolation Storage Rack

8.4.2 Verifying the Isolations (Second check) OIC Isolation sheet ‘Checked by’ the OIC for work: the OIC is responsible to:

• physically verify and record that all isolations have been performed as shown on the Isolation Sheet • where is it not possible to physically verify the isolation point (e.g. HV switchgear in switch room), a

suitably competent person is to verify the isolation on behalf of the OIC • verify that the Isolation Storage Rack contains the red Isolation Key/s, secured by the green PTWO

Lock • verify the isolation boundaries are sufficient to allow the work to be undertaken (Seek clarification from

the PTWO as required) Note: During overhauls and outages this role can be performed by a PTWO separated by time and space, where relevant, from the plant isolation process. When the isolation sheet has already been ‘Checked by’ another OIC: The OIC is responsible to:

• verify that all isolations have been “Second Checked” and recorded on the Isolation Sheet • verify that the Isolation Storage Rack contains the red Isolation Key/s, secured by the green PTWO

Lock • verify the isolation boundaries sufficient to allow your work to be undertaken



8.5 Issuing the PTW

The isolations have been completed and the Permit is ready to be issued to the OIC. OIC collects the PTW from the PTW office in preparation to complete the work. Figure 8.4 Issuing the PTW

9 SPECIAL PURPOSE ISOLATIONS AND PROCESSES

9.1 Access PTW

An Access PTW can be used when work is required on operational or non-operational plant that does not require an isolation to secure energies. The Access PTW provides a structured process and control to complete work. The Access PTW has the same status as a normal PTW. For example, an Access PTW can be issued for work where:

• an isolation is not required • the work contains High Risk Hazards (see Section 11) • The work can extend beyond a shift (12hrs)

NOTE: if the 2x2 TRA identifies the inherent risk of the task as being low section 9.2 Performing Minor Tasks on Live Plant can be considered.

9.1.1 Process to Apply for an Access PTW An Access PTW does not require isolation at any stage to complete the activities under the PTW. An Access PTW can be applied for using the same process as a standard PTW. Refer to section 8.1. An Access PTW does not require an isolation sheet to be drafted or isolations completed. Therefore, Sections 8.3 and Section 8.4 do not apply. An Access PTW shall be treated as a PTW issued for Work. Section 8.5 onwards applied to an Access PTW.

9.2 Performing Minor Tasks on Plant

The process for performing minor tasks on plant is available for specific low risk activities (as identified using the 2x2 Task Risk Analysis process) that are to be completed while the plant is in operation. The process provides control to ensure the task is undertaken and communicated safely. It can only be used for tasks that have been inherent risk assessed as low and for example may include, but not limited to:

• fault finding • control circuit testing • general greasing • condition monitoring, and • general cleaning (including coal spills, minor lagging work and work where the plant is considered

operational) This procedure only

This procedure is not to be used for any work that involves High Risk Hazards (see Section 11) as defined in the PTW suite e.g. hot work, confined spaces, live electrical work.

applies to mechanical and extra low voltage electrical work where voltage levels are below 50V AC or 120V DC systems.

Refer to CS-PTW-SOP-05 Permission to Perform Minor Tasks on Plant for further direction.

9.3 Own Isolation

Own Isolation is the process of allowing an OIC authorised by the site PTW Administrator, to conduct their own isolation. Own isolations shall be limited to non-operational plant, requiring single point isolation and be undertaken via the use of a PTW Own Isolation. Refer to site specific Own Isolation procedure for further direction.



9.4 Specified Apparatus

The Specified Apparatus process is an extension of the Own Isolation process where an Authorised Person (authorised by the site PTW Administrator), can apply isolations and complete work on a specified apparatus. This process applies to operational and non-operational plant. There shall be a maximum of 5 isolation points and 3 work party members to carry out this work and restricted to apparatus that is listed in the Specified Apparatus Register. Where the above criteria cannot be met, a normal PTW is to be used to complete the work. Refer to site specific Specified Apparatus procedure for further direction.

9.5 Operator Standby

The Operator Stand-by process is used where it is agreed by the PTWO and OIC that the residual risk of the task is low (JSEA). Operator Standby involves using a plant operator to stand-by an isolation point without locking it out while small repairs are being carried out on that plant. The plant operator (standby person) is to isolate the point and must stay at the isolated point and be in contact with the worker at all times while the task is being undertaken. It shall be used for work involving a maximum of 3 isolation point. Once the task is complete the plant operator (standby person) is to restore the plant to service. The period of isolation (to complete the task) under the Operator Standby process should not exceed 20 minutes. If period of isolation is expected to exceed 20 minutes, a PTW is to be used. Refer to site specific Operator Standby procedure for further direction.

9.6 Multiple OIC PTW

Where a PTW requires continuation of work across shifts, the PTW will need multiple OIC’s to complete the PTW activities. Refer to CS-PTW-SOP-03 Multiple OIC procedure for further direction.

9.7 Using International Technical experts under the PTW System

Where a job requires the use of an international technical expert (non-English speaking) specific provisions are permitted to ensure a guardian is appointed to accompany the expert and fulfil their role under the PTW. Refer to CS-PTW-SOP-04 Using International Technical Experts in the PTW System.

9.8 Electrical Isolation with Multiple feeds

Where the isolation process for a PTW involves multiple feeds (HV and/or LV), the electrical isolations with multiple feeds must be managed by an approved switching sheet. The switching sheet preparation and operation shall only be performed by an authorised and competent Switching Officer and Switching Officer Assistant. Refer to CS-OHS-53 High Voltage Isolation and Access and site specific procedures for further direction.

9.9 High Voltage Isolation (single feed) for electrical work

All high voltage electrical isolations shall comply with CS-OHS-31 Electrical Safety Management procedure. Refer to CS-OHS-31 Electrical Safety Management procedure for further direction.
