1 PURPOSE

The Permit-to-Work (PTW) process ensures that appropriate steps are taken to identify and manage work with hazards and risks to people that have the potential for a fatality risk or a significant environmental or equipment event.

The PTW process requires that:

The boundaries and scope of work are identified and communicated.

The appropriate clearance certificates are identified and completed for the work activities that have the potential fatality risk, or significant environmental event to ensure that the controls have been implemented and are effective.

A formal process for facilitating the Hand-Over and Hand-Back of clearance certificates, facilities, plant and equipment is maintained.

Effective management and communication of Simultaneous Operations (SIMOPS), with the potential for fatality risk, occurs within areas and work groups.

Compliance with legislative requirements and procedural controls, e.g. BHP Our Requirements’ document and the Integrated Management System requirements are maintained.

Note: Work without SIMOPS and not requiring clearance certificates is to be managed using the Task Hazard Analysis (THA) Procedure Doc no. 000037634.This document supports IMS Element 14: Systems of Work Standard.

2 SCOPE

This document applies to Olympic Dam employees and contractors involved in planning, execution and supervision of field-based work.

To ensure accuracy of information, this document will only be amended once relevant stakeholders and subject matter experts have been identified and consulted i.e. risk owner, control owner/s, process owner/s, process implementer/s etc. These stakeholders and subject matter experts will also be included in the document control process.

5 PROCEDURE STEPS

Refer to the process flow chart when reading the procedure steps. Clearance certificates define the minimum controls to prevent incidents with potential for a fatality risk, or a significant environmental or equipment event, or as a result of a legislative requirement (e.g. Confined Space entry).

Clearance certificates are used in conjunction with either a THA or WI combined with an IMS Element 14 -Permit to Work Process WI Handover – Hand back Form, Doc No. 000119419, to constitute a permit to work.

The use of THA/WI is used within this document to represent work under the permit to work process – there is no separate permit to work form.Appendix A, to be used in the job planning stage or during work preparation, to identify the relevant clearance certificates required.

5.1 Review THA/WIJob Owner to complete or validate the THA/WI for the scope of work and identifies potential clearance certificates required for the scope of work.

Job Owner, preferably with the Work Executor(s), to inspect the job site prior to commencement of the task to ensure identified controls are detailed in the risk assessment (THA / contained in the WI) and will be effective.

Job Owner to identify any simultaneous work (SIMOPS) being conducted and to effectively manage the interactions between work groups and is responsible to ensure SIMOPS affecting their scope of work and/or persons or work crew have been identified and are effectively managed.

Notes:

The WI must be an approved WI, as per the OD Controlled Document Management process requirements, otherwise a Task Hazard Analysis (THA) is required.

The THA must meet the requirements of Task Hazard Analysis, Doc No. 000038526.

1. THA or WI reviewed for scope of work

2. Job site inspected to determine controls and clearance certificates required

OUTPUT:

3. Potential SIMOPS identified by Job Owner

5.2 Clearance certificate required?Job owner shall determine if any clearance certificates are required for the proposed scope of work using the list of clearance certificates in Appendix A as a reference.If it has been determined that clearance certificates are not required, proceed to Step 5.2.1

If it has been determined a clearance certificate is required, proceed to Step 5.3.

OUTPUT: 1. Determination made if clearance certificates are required for scope of work

5.2.1 Authorise THA/WIArea Owner together with the Job Owner shall confirm:

The specific equipment/ area being worked on

The relevant clearance certificate(s) have been authorised by a competent person/s.

Safe handover of the equipment/area has been made to the Job Owner.

Area Owner to retain the original THA/WI and any other relevant documents in the agreed permit management location (e.g. permit hut, confined space/mobile ILB etc.) This original document is where all sign on signatures and changes are captured.

Job Owner shall maintain a copy of the current THA/WI and clearly it as a copy which shall be kept at the job site to be used as a reference document if/when required.

Where SIMOPS have been confirmed the Area Owner shall update the Area Owner Work Register (scope of work title, status, location, Job Owners name and contact details).

Notes:

Should the Area Owner identify changes that are required to be made, the Job Owner will be expected to complete/facilitate completion of these changes before prior to the Area Owner authorising it.

Subsequent Re-Authorisation of the work to be recorded on the Re-Authorisation, Work Suspension & Job Owner Transfer sheet of the THA or WI HO/HB cover sheet.

Where an electronic Area Owner Work Register is not available or not functioning, then the Area Superintendent must determine an alternate but equal means of communicating active work information within the area. This may include (e.g. Whiteboard, paper log sheet etc.) that contains equivalent information.

Area Owner can give verbal authorisation to work team to go ahead on a daily basis if they are working under the remote area safety procedure.

Note: Should a clearance certificate not be required for the work, then after the THA/WI has been authorised, proceed to Step 5.5.

OUTPUT: 1. THA/WI for work not requiring clearance certificates is authorised

5.3 Prepare relevant clearance certificates for execution of the workJob Owner to facilitate the completion of all the relevant clearance certificates associated to the scope of work. These clearance certificates will outline the required controls and other associated documents that must be implemented to allow the safe execution of the task.

Job Owner shall establish the effective implementation of the required controls identified in the relevant clearance certificates.

Note: The specific details for completing and authorising each of the clearance certificates covered in Appendix A refer to the relevant procedure associated with the relevant clearance certificate.Job Owner shall establish a complete work pack consisting of THA or WI including a Handover/Hand back cover sheet, all relevant clearance certificates and any other relevant documents related to the scope and proceed to Step 5.4

The scope of work is correct and can be conducted without SIMOP’s conflicts.



The boundaries of the task are discussed and understood by the Job Owner.

That the Job Owner has appropriately completed the relevant clearance certificates and understands the implementation requirements of the controls identified on the clearance certificate for the work to be performed safely.

The relevant clearance certificate(s) have been authorised by a competent person/s.

The Area Owner shall determine the frequency they will review the task based on the risk associated with the task and area the task is being conducted. Which shall be updated on the front page of the THA work sheet or WI Hand over/hand back cover sheet.

Area Owner to sign the Hand over section of the THA/WI coversheet.

Area Owner to apply a uniquely numbered hasp to the relevant ILB and record the hasp number along with the Isolation lock box number on the front page of the THA or the Hand over hand back cover page of the WI for jobs involving Level 2 isolations as a control

Safe handover of the equipment/area has been made to the Job Owner.

Area Owner to update the Area Owner Work Register (scope of work title, status, location, Job Owners name and contact details).

Notes:

Should the Area Owner identify any additional controls that require a clearance certificate, (Confined Space entry, hot work etc.) then the Job Owner will be expected to complete/facilitate completion of these before the Area Owner authorises the associated THA/WI.

Subsequent Re-Authorisation of the work to be recorded on the Re-Authorisation, Work Suspension & Job Owner Transfer sheet of the THA or WI HO/HB cover sheet.

Where an electronic Area Owner Work Register is not available or not functioning, then the Area Superintendent must determine an alternate but equal means of communicating active work information within the area. This may include (e.g. Whiteboard, paper log sheet etc.) that contains equivalent information.

5.4.1 Handover AcceptedThe Job Owner shall accept the conditions of the work pack by signing the Job Owner acceptance section of the THA/WI hand over hand back cover sheet.

NOTE: Area Owner and the Job Owner shall record their worksite checks where relevant by dating and signing the Area Owner/Job Owner checks column of sign-on sheet of the THA / WI HO/HB cover sheet, Doc No 000119419

If No, Proceed to Step 5.10.2

5.10.1 Facilitate Job Owner TransferIf the work is a continuation across shifts/work teams and the scope of the work has not changed, then an Area Owner can authorise the new Job Owner by following the below instructions:

Area Owner to confirm that the incoming Job Owner is trained and competent (minimum of carrying a JO card)

The incoming Job Owner in consultation with the outgoing Job Owner and an Area Owner shall conduct an infield walk around and complete a TTTC to assist in the review of all aspects of the task including:

Scope of work and the current status of the work

The location of the work and/or the equipment that is being worked on

Boundaries of the work are discussed and understood

All hazards, controls and Simultaneous Operations (SIMOPS) for the task

Clearance certificate requirements, to ensure they are completed to the required standard and attached to the work pack

The incoming Job Owner shall then review the THA/WI to verify that everything discussed/identified during the walk around is appropriately covered by the current THA/WI to reduce the risk to as low as reasonably practical. If not and changes are required, Proceed to Step 5.1

If no changes are needed, proceed as per below:



Area Owner shall authorise the new JO by signing the Area Owner’s part of the re-authorisation page within the THA/WI HO/HB cover sheet.

The in-coming (new) Job Owner shall sign the Job Owner’s part of the re-authorisation page within the THA/WI HO/HB cover sheet and any relevant clearance certificates.

The in-coming (new) Job Owner shall hand Personal danger lock and completed Job Owner’s danger tag onto the relevant ILB hasp (where level 2 isolation are being used as a control for the task)

The outgoing JO shall sign in the Transferred column of the re-authorisation page of the THA/WI HO/HB cover sheet. (Where level 2 isolation are being used as a control for the task remove their Personal danger lock and completed Job Owner’s tag from the relevant ILB has)

Transfer complete, Proceed to Step 5.5

Notes:

Work executers can remain on the job during a Job Owner’s transfer if/when needed, this is why the AO authorises the new JO and the incoming JO must be signed on before the outgoing JO signs the transferred column of the re-authorisation section of the THA work sheet. (The incoming Job Owner shall determine if they will allow WE’s to remain on the job during the Job Owner transfer before the transfer begins)

The incoming JO must notify the WE’s before conducting a JO transfer.

1. The incoming Job Owner has determined if they will allow the current WE’s to remain on the job whilst they conduct their Job Owner transfer.

OUTPUT:

2. Safe and effective Job Owner transfer of work between Job Owners completed in consultation with an Area Owner, JO then Proceeds to step 5.5 and follows work flow to get new WE’s onto the job.

5.10.2 Suspend work.Where work is not complete and a transfer between Job Owners is not possible:

Job Owner and Area Owner must collaboratively determine the suitable safe state or condition for the equipment

Work Executors to stop work (Remove their personal lock and danger tag if applicable)

All clearance certificates must be managed, refer to the detailed clearance certificate procedures to determine the requirements

Job Owner to sign the Work Suspended column of the Re-Authorisation and Work Suspension Job Owner transfer sheet on the THA or WI HO/HB cover sheet and place all documents back into the permit management location for safekeeping.

Job Owner shall remove their Job Owner tag and personal danger lock from the Isolation Lock Box hasp and place an completed Out-of-Service tag on there (where Level 2 Isolations are associated with the task)

The Job Owner shall notify the Area Owner why they have suspended the task and when it is likely to continue

Area Owner shall update the Area Owner work register.

Work Suspension complete.

NOTE: New Job Owners to Proceed from Step 5.8

1. Work has been suspended, to be continued later from Step 5.8OUTPUT:

2. Work status communicated between Job Owner and Area Owner and the AO register is updated.



5.11 Follow hand-back requirementsIn consultation with the Area Owner the Job Owner shall conduct an infield walk around to ensure that:

The scope of work is complete as intended

The Equipment/Area is in a safe operational state e.g. area clean, machine guarding back, parts and equipment used for task removed from area etc.

All Work Executor’s have removed their personal lock and danger tag from the relevant ILB Hasp (Where isolations where being used as a control)

All clearance certificates have been closed (refer to the detailed clearance certificate procedures to determine the requirements)

Job Owner “hands back” to the Area Owner by signing the ‘handback” section on the THA/WI HO/HB cover sheet.

Job Owner shall hand all associated documents for the task to the Area Owner for review and acceptance of the handback.

Note: If someone has lost their key and the forced removal of a personal lock is required, refer to Management of Isolation, Doc No. 000056428.

1. Area Owner and Job Owner have confirmed the work is complete. OUTPUT:

2. Job Over “hands back” to the Area Owner by signing the ‘handback” section of the THA WI.

5.12 Accept Hand backThe Area Owner shall ensure:

All associated documents for the task has been received from the Job Owner

Area Owner confirms the acceptance of the hand back by signing the Hand back acceptance section of the THA/ WI HO/HB cover sheet.

Area Owner updates the Area Owner work register.

Note: If someone has lost their key and the forced removal of a personal lock is required, refer to Management of Isolation, Doc No. 000056428.

1. All associated documents for the task has been received by the Area Owner for review and acceptance of the handback.

OUTPUT:

2. Area Owner has accepted the hand back.

5.12.1 Record KeepingThe Area Owner shall collate all documentation associated to the task and archive it the permit management location for a period of 3 months.

Disposal after this period shall be via the relevant OD disposal of records requirements.

NOTE: Any documentation involved in an incident shall be attached directly to the event notification in EMS.

OUTPUT: 1. All documentation associated to the task is archived to ensure it auditability if/when required.

5.12.2 Failure to Hand backIn the event that a Job Owner fails to facilitate a Job Owner transfer/Work suspension the Area Owner shall contact the Job Owner who has failed to facilitate a Job Owner transfer/Work suspension prior to leaving site and request that they return to work and do so.



Where it is determined it’s either unsafe or it’s unrealistic that they can return to facilitate a Job Owner transfer/Work suspension within in a suitable time frame the Area Owner shall escalate to the Area Superintendent / Duty Manager.

The Area Superintendent / Duty Manager shall:

Confirm with the main gate that the individual is swiped “offsite”, and

Contact the Job Owner by phone to discuss the task/area and its current status to ensure full understanding of the task hand over information, and

Review the TTTC card that the new Job Owner and the Area Owner have completed (on the job) to ensure real time hazards including SIMOPS have been considered, and

Area Superintendent / Duty Manager can then allow an Area Owner to authorise a new Job Owner onto the task without the previous Job Owner having signed the Transferred or Suspended columns of the Re-Authorisation, Work Suspension & Job Owner Transfer section of the THA/WI HO/HB cover sheet.

The Area Owner with support from the Job Owner will then raise an Event Notification in EMS for follow up and data capture.

8.3 Appendix C – Temporary Transfer of Area OwnershipOccasionally situations arise that may be suited to conduct a temporary transfer of Area Ownership, as defined by the Permit to Work process. A common example of this would be to Transfer Area Ownership of a small area to a Project lead for a certain period/phase of a long-term project.

This transfer of Area Ownership requires the new owner of the area e.g. Project Lead to take on the full accountabilities of the PTW process in that area for a specified duration of time. (e.g. the duration of the project period/phase) including the authorisation process for projects personnel to perform PTW roles within the defined area such as Area Owners.

To manage the risks involved in the temporary transfer of Area Ownership the following process shall be followed for each transfer of area ownership:

1. Incoming (new) Area Superintendent/Project lead and current Area Superintendent shall determine if the transfer of Area Ownership can be limited to non-operational plant areas, where clear demarcation of the area is possible.

2. Incoming Area Superintendent to initiate a temporary Management of Change (MOC) via the OD MOC Process.

3. Ensure a Risk Assessment (e.g. RRRA) is conducted to ensure the inherent risks of the area are known and managed by the incoming temporary Area Superintendent as Owner of the Area.

4. Identify the process to establish competent and authorised Area Owners and Authorised Isolators for the temporary change area.

5. Use the PTW Temporary Area Transfer Form (Document # 011816978) and attach to the MOC (include handback process).

6. Obtain authorisation for the transfer from the original Manager of the Area as a minimum.



8.4 Appendix D – Area Ownership MapThe application and governance of the OD Permit to Work Doc No. 000056567 requires definition of ownership of all Permit to Work areas (and certain services) at the Superintendent level.

This Appendix visually demonstrates these physical areas and boundaries at Area Superintendent Level and supplements the information in the OD Battery Limits, Doc No. 000099773. The underground section of the Mine has not been included at this time.

Further to the maps and information provided below, the Element 14 - PTW and Isolation Training Pathways, Doc No. 012275829 has been cross-referenced to identify the current owners of the areas and the specific training and authorisation requirements.

Maps are high level and may have overlap; please contact the assigned Area Owner for more detailed information.
