1. INTRODUCTION

1.1 Purpose of the Permit to Work System

This document describes the workings of the Permit to Work System (PTWS) as used on the Dampier to Bunbury Natural Gas Pipeline (DBNGP). Its scope includes -

all DBNGP assets, including activities associated with construction of new assets within the licence area;

other assets operated by DBP; and maintenance contracts undertaken by DBP, unless otherwise specified.

The PTWS is a formal, procedural system used to plan, control and complete work according to safe work practices. The PTWS requires communication and coordination between Management, Supervisors, Site Coordinators, Permit Issuing Officers, Permit Holders and those who execute the work; each of whom has defined responsibilities under the System.

The essential elements of a Permit to Work System are -

clear identification of who may authorise particular jobs; clear understanding of any limitations of the various Authority Levels; clear understanding of who is responsible for specifying the necessary precautions; effective training and instruction in the use of the System; and monitoring and auditing to ensure that the System works as intended.

1.2 Objectives of the Permit to Work System

The objective of the PTWS is to provide a mechanism to assist in the protection of personnel, equipment, and environment by managing the activities to ensure that identified controls and procedures are adequate and implemented in a consistent manner.

On its own, the PTWS does not make the work safe but effectively elevates awareness of the work. Whilst a Permit Holder, Permit Issuing Officer or Site Coordinator is not expected to be an expert in the details of the activities being undertaken, he or she needs to be familiar with the system being implemented by the Permits and its purpose, and be trained, competent and approved to hold such positions by DBP.

The PTWS has the following key objectives -

ensure proper authorisation of work; ensure that all hazards are identified, work is coordinated and controlled; make clear to personnel carrying out the work and site management to -

identify the exact scope of work; state the safety requirements for the job; nominate the precautions required and the term of validity of the Permit;

ensure that personnel responsible for the work are aware of all the work being carried out in or near their area;

provide a formal hand-back procedure to ensure the area affected by the work is safe to return to normal operation;

ensure effective control of hazards and work in cases of concurrent conflicting work which individually may not compromise safe working procedures, but which in combination could create the potential for hazards;

manage the interface activities that may impact on operational area;




provide a record to show that a safe system of work has been used and that the necessary precautions have been considered and executed;

define training and accreditation; monitor system performance; and meet all regulatory and legislative requirements.

Once the PISA Authority (Duty Gas Controller) has authorised the PISA, the Permit Issuing Officer (as the Permit Holder for the PISA) completes the PISA Acceptance.

5.2.3 Section 3 of PTW Form - Authorisations

Once all the conditions on the Permit have been satisfied, the Permit Holder completes the Permit Holder Authorisation.

The Permit Issuing Officer shall complete the authorisation when he/she is satisfied it is safe to start work and has -

conducted all necessary isolations; conducted the initial gas test and specified ongoing testing requirements; checked the work site personally to ensure that it is safe to start work as per the

conditions and precautions stated on the Permit and all its attachments; and discussed the conditions and precautions stated on the Permit and all its attachments

with the Permit Holder to confirm that they are understood. Once the date, time, name and signature of the Permit Issuing Officer are completed, work as per Section 1 of the Permit can commence. The Permit Holder shall show the entire work team where to place their Personal Danger Tags (where required). The work group (Permit Accepters and Permit Holder) shall sign onto the Permit by detailing their name, date, time and signature on the back of the PTW Form.

If work has not commenced within two (2) hours of the Authorisation the Permit Holder shall return to the Permit Issuing Officer for Permit re-validation.

5.2.4 Section 4 - Changes of Permit Authorisers

All changes of Permit Authorisers (i.e. Permit Holder, Permit Issuing Officer or Site Coordinator) shall be indicated in the “Change of Permit Authorisers” section of the PTW Form. If a Permit Authoriser has to leave the site for any reason a new Permit Authoriser shall be appointed.

There shall only be one (1) change of Permit Authoriser, i.e. PH, PIO, or SC, per job.

Where a permit has a related Pipeline Integrity and Supply Authorisation (PISA), changes to Permit Authorisers shall be communicated to TSCC.

5.2.5 Location of Copies

The original copy of the Permit for jobs in progress is to be kept on the appropriate Site Permit Board.

In addition, locations will be provided for Long Term Isolations, Relinquished Permits, Suspended Permits, and Permits Awaiting Isolations. It is the responsibility of the Permit Issuing Officer to ensure that the original copy is posted on the Site Permit Board.

It is the responsibility of the Permit Holder who accepts the Permit to ensure that the pink copy is posted at the work site (i.e. on-the-job).




5.2.6 Periods of Validity

All permit to work certificates will be valid for a period of no more than one shift. All PISA are valid for the duration of the activity. All Permits (HSE 1-1 FM) are valid for the duration of the activity.

At the end of each shift, both copies of the Permit and associated certificates (original and site) shall be returned to the Permit Issuing Officer. If the work is to continue, a new certificate must be issued for any relevant activities. The Permit shall be handed over by the outgoing PIO and re-issued to a new PIO and Permit Holder. The permit must then be signed by the Permit Issuing Officer after verification of relevant conditions and consideration of other planned work.

When work has been completed the Permit shall be signed off by the Permit Holder in the presence of the Permit Issuing Officer. (Refer to Section 5.7 Permit Closure).

If personnel are not returning to the job, they shall sign off on the PTW Form and remove their locks and personal danger tags from all isolations.

5.2.7 Section 5 – Suspension and Recommencement of a Permit

Where work is being carried out and cannot progress due to an incident related to the job, shift change / carry-over, non-availability of parts, non-availability of adequate Work Instruction or JHA, or non-availability of personnel, then the Permit may be closed or suspended until the work is able to progress. The suspension process allows for a record of isolations which may need to stay in place until the proposed work is completed.

When the work is suspended, the Permit Holder completes Section 5 of the Permit by writing the date and time in the STOP column, and informs the Permit Issuing Officer.

Isolations associated with the Permit are to remain in place.

The Work Team (i.e. Permit Accepters and Permit Holder) are to remove their Personal Danger Tags and sign off the Permit at the time of suspension.

The Permit Issuing Officer retains the suspended permit until required by a Permit Holder. TSCC shall be notified of the Permit Suspension to ensure that visibility is maintained and that should any alarms occur during the period of suspension the relevant PIO can be informed by TSCC.

When the work can recommence, the Permit Issuing Officer informs the Permit Holder and TSCC. The Permit isolations and hazards are checked by the Permit Holder and Permit Issuing Officer prior to work re-commencing. The Permit Holder completes Section 5 of the Permit by writing the date and time in the START column.

The Work Team (i.e. Permit Accepters and Permit Holder) attach their Personal Danger Tags and sign onto the Permit.

Work can then resume.

5.2.8 Permit Breach

A breach of the Permit conditions shall always be brought to the attention of the Permit Holder by the person witnessing the breach. On report of any breach of conditions, the Permit Holder shall make the work area safe and stop the work immediately until the situation can be discussed with the Permit Issuing Officer. Failure to adhere to the




conditions of the Permit shall result in closure of the Permit. If the Permit Holder does not stop the work and/or correct the breach, the witness shall then report the breach to the Permit Issuing Officer for action.

5.3 Shift Changes and Permits

During changeover of shifts there is an increased potential for a breakdown in communication. The following procedures will assist in eliminating this.

5.3.1 Permit Issuing Officer (including Site Coordinator)

For Permit Issuing Officer shift changes, the oncoming Permit Issuing Officer shall be familiar with all Permits for work in progress and work suspended to satisfy themselves that work can safely continue.

Once the new Permit Issuing Officer is familiar with all work in progress, then the appropriate signatures are made in the Change of Permit Authoriser section of the Permit (Section 4).

5.3.2 Change of Permit Holder

Where there needs to be a change of Permit Holder, the current Permit Holder shall ensure that the work site is left in a clean, safe and orderly condition with no walkways, emergency equipment or escape ways obstructed.

A departing Permit Holder shall advise the Permit Issuing Officer of the job status and return the Permit to the Permit Issuing Officer. The Permit Holder and/or Permit Issuing Officer shall appoint a new Permit Holder and conduct a briefing on the job, its status, the precautions applied, and isolations in place.

The Permit Holder accepting the Permit shall place their Personal Danger Tags on any isolations before the relinquishing Permit Holder removes their Personal Danger Tags. Once the new Permit Holder is familiar with all relevant permit requirements, the appropriate signatures are made in the Change of Permit Authoriser section of the Permit (Section 4).

5.4 Isolation and Tagging

For a full explanation of the isolation and tagging system used on the DBNGP, refer to the procedure HSE 3 PR Isolation and Tagging.

For specific tasks, isolation lists are included in the relevant Work Instruction or Procedure.

Where isolations are not covered by a Work Instruction, then an Isolation List (HSE 3-1 FM) must be numbered, completed and attached to the Permit.

5.5 Handing Back Work

When the work is complete, the Permit Holder shall ensure the work site is left in a clean and safe condition, all personal danger tags, temporary signs and barriers are removed.




The Permit Accepters (Work Team) shall sign off on the Permit. The Permit Holder shall return all Permit copies and documentation to the Permit

Issuing Officer and signs off on the Permit Closure section of the Permit original in the presence of the Permit Issuing Officer.

The Permit Issuing Officer is then required to organise the following, but not limited to - a site inspection to check that the equipment / work site is ready to return to normal

operations; de-isolate, or arrange an authorised personnel to de-isolate, all isolations nominated

on the Isolation List / Certificate; and return of the equipment to service in the presence of the Permit Holder, if possible,

to ensure that the equipment repairs have been successful. NOTE: If the work is incomplete; the PH should inform the PIO who will address this using the out of service system by raising a work order in MAXIMO and the equipment must have an Out Of Service (OOS) tag attached as required.

5.6 Section 6 – Permit Acceptors

All permit acceptors must agree to abide by the work conditions and controls as outlined in the Permit to Work and as directed by the Permit Holder; this includes the associated JHA, Certificates and isolation lists. All permit acceptors must acknowledge and sign on and off the Permit.

NOTE: the Permit Holder must also sign on and off in this section.

5.7 Section 7 – Permit Closure

Once the requirements of Section 5.5 have been fulfilled the Permit Issuing Officer shall sign off the Permit Closure declaration. Copies of all relevant paperwork shall then be sent to the relevant department for filing (DBNGP Planning Files / Projects Files).

NOTE: refer to the PISA procedure, HSE 34 PR for closing a PISA related to the Permit.

5.8 Emergencies and Permits

In the case of an emergency, the Permit Holder shall -

instruct the work team to cease work; instruct the work team to make the work area safe and proceed to the emergency

muster point immediately; return the Permit to the Permit Issuing Officer so that it may be suspended (refer to

Section 5.2.7); and liaise with the Permit Issuing Officer for further instructions.

Once the all clear has sounded the Permit shall be re-validated (START) in Section 5 of the Permit (Suspension and Recommencement of Permit) prior to re-commencement of any work.

6. PERMIT SYSTEM TRAINING AND AUTHORISATION REQUIREMENTS

All users of the Permit to Work System shall receive structured training so as to achieve competency in authorisations for the Authority Levels required.

Refer to the DBP Permit to Work Authorised Persons Competency Matrix in Appendix 2.




The training shall be conducted under the DBP Training Management System and shall include competency tests. The results of this competency testing are to be recorded to provide confirmation of individual results.

These results shall be considered, in addition to relevant work experience and familiarity with the DBNGP, prior to making any formal appointments within the Permit to Work System.

The recorded results will also assist in the identification of personnel scheduled for re-training. The training and testing will be at the following levels -

Permit Issuing Officer / Site Coordinator; Permit Holder; and Permit Accepter.

The Permit to Work training shall cover such details as, but not limited to -

State and Federal legislative requirements; industry and corporate guidelines and documentation; objectives of the Permit to Work System and knowledge of the written procedures; requirements and procedures relevant to each role, e.g. gas testing, work site

procedures; roles of individuals and approving authorities, HSE Permit types and Certificates, e.g. Hot Work, Confined Space Entry, Working at

Heights, Excavation Entry; validation and required signatories; restrictions, e.g. conflicting work, changing conditions; and isolation and tagging procedures, if applicable.

7. PERMIT TO WORK SYSTEM PERFORMANCE MONITORING

In order to ensure that the PTW System is able to provide the maximum benefit in controlling hazards, the performance of those working within it shall be measured periodically.

Any resulting reports shall be reviewed by the Gas Transmission Leadership Group and line management, who have the authority and responsibility to ensure that any action items are pursued and completed.

7.1 Permit Monitoring

It is a requirement of the PTWS that the Permit Issuing Officer perform regular inspections of active work sites. As a spot check, the inspection shall cover correctness of the Permit, safety equipment in use, and compliance with precautions and conditions defined by the Permit.

7.2 Periodic Internal Review

In addition to the regular inspections and audits, a more formal in-depth review is to be performed by the Superintendent/Manager once per year (Note - for project work, audits shall be undertaken in accordance with the Project Audit Schedule). This review shall be based on all of the key objectives set out in Section 1.2 of this procedure and specifically cover the items listed in the Permit to Work - Field Audit Checklist (HSE 1-3 FM) and Permit to Work - Internal Audit Checklist (HSE 1-4 FM).




7.3 Annual Audit

Once per year a detailed audit of the PTWS shall be undertaken by HSE / Technical Compliance. In addition to the tasks listed above, the adequacy of the system in terms of the work activity undertaken and the procedures in place shall be examined. This type of audit examines the fundamental design of the system and shall include a person with proven experience in the design, operation and auditing of PTWS external to DBNGP. This audit report shall be presented to the Gas Transmission Leadership Group and line management for consideration and action.
