1.01.0 Course PurposeCourse Purpose

• This training course is designed to give new employees a clear understanding of the Permit To Work system as it is applied in TSP Production Operations (refer TSP Permit to Work Procedure: TPS-P-PR-PRD-MET-001TPS-P-PR-PRD-MET-001)

• It is important to note that staff training on making out and using work permits is a continuouscontinuous exercise

• Staff need to refer to this document which clearly defines the procedure and the types of permit available.Note also that a separate Procedure (PR-PRD-MET-002) covers offshore wellhead platforms

• All personnel working on site must be familiar with the procedure so everyone is aware of the risks and can make their own contribution to overall safety


SOUTH PARS

2.02.0 Permit to Work ProcedurePermit to Work Procedure

The primary purpose of this Procedure is to ensure that written permission, in the form of an approved Permit to Work, is correctly issued to allow authorised personnel to perform clearly defined tasks

It is further to ensure that nothing is done, during the performance of these tasks, to prejudice the safety of personnel or the installation

In particular, the following points must be observed:

•Correct operation of the Permit to Work (PTW) System is Correct operation of the Permit to Work (PTW) System is achievedachieved

•All necessary personnel are aware of the safety precautions to All necessary personnel are aware of the safety precautions to be takenbe taken

3.03.0 The Permit to WorkThe Permit to Work

• The Onshore Permit to Work System is based around the use of Main Permits to WorkPermits to Work that cover all classes of work, whether carried out by Company employees or Contractors

• Certain specific defined tasks also require Complementary PermitsComplementary Permits in addition to the main Permits to Work

• Furthermore, certain routine tasksroutine tasks, which do not create any potential hazard to personnel, equipment, or the site, will notnot require a Permit to Work. Such tasks are listed by the Process and Shift Superintendents/Supervisors for the areas under their control. These listed tasks must be covered by detailed Procedures to ensure safe performance and must have written approval from the Operations Assistant, Phases 2 & 3


SOUTH PARS

4.04.0 Types of Permit to WorkTypes of Permit to Work

There are three, Main Permits to Work: three, Main Permits to Work:• Main Hot Work (Naked Flame) Permit • Main Hot Work Permit• Main Cold Work Permit

4.14.1 Main Hot Work (Naked Flame) PermitMain Hot Work (Naked Flame) Permit

A main Hot Work (Naked Flame) Permit is required for any work involving equipment iving rise to a definite source of ignition, including, but not limited to, use of equipment for oxy-acetylene burning, gas welding, electric-arc welding, propane torch heating and burning, grinding or use of a hot-air gun

This permit is identical to Main Hot Work Permit but clearly stamped ‘Naked Flame’


SOUTH PARS

4.24.2 Main Hot Work PermitMain Hot Work Permit

A main Hot Work Permit is required for any work involving, or giving rise to, a potential source of ignition, including, but not limited to, grit blasting and work on non-intrinsically safe equipment. A Hot Work Permit is also required for electrical work, unless the equipment is fully isolated

The Area Authorities and safety Authorities may refuse or postpone Main Hot Work Permits, particularly the Main Hot Work (Naked Flame) Permits, if they consider that the prevailing conditions are not suitable for several simultaneous hot work activities


SOUTH PARS

4.34.3 Main Cold Work PermitMain Cold Work Permit

A main Cold Work Permit is required for all work that is not covered by the Main Hot Work Permits and Main Hot Work (Naked Flame) Permits described previously

8.08.0 ProceduresProcedures

8.18.1 Administration of PermitsAdministration of Permits

The Operations Assistant Phases 2 & 3 has the ultimate and overall responsibility for the implementation of the Permit to Work Procedure and also for limiting the number of Permits that are valid at any one time

The routine administration of the Permit to Work procedure is carried out by those persons designated by the Operations Assistant. These designated persons are responsible for:

•Issue of the Permits•Management of the work progress•Revalidation or cancellation of Permits


SOUTH PARS

8.28.2 Procedures Applicable to All PermitsProcedures Applicable to All Permits– The top (White) copy of all main Permits to Work and

any associated Supplementary Permits, are retained by the person performing the work, or in charge of the group performing the work. White copies of PTW’s must be clearly displayed, and available for inspection at all times at the work sites

– It is the responsibility of all personnel involved in the work to ensure that the conditions stated on the Permit are maintained throughout the duration of the work

Every Main Permit to Work mustEvery Main Permit to Work must:

• Clearly define the specific item of equipment to be worked onClearly define the specific item of equipment to be worked on• Show the precise location and exact nature of the work to be doneShow the precise location and exact nature of the work to be done• List the number of persons in the working teamList the number of persons in the working team


SOUTH PARS

– All Permits are automatically suspended on the raising of any Emergency Alarm. Only when the situation is back to normal may the work be resumed. The Permit must be endorsed to show the break in the work and the times of the interruption

– During any interruptions, the work sites must be patrolled by the Production Operators and Safety Authority to ensure that all personnel are aware of the change in conditions

8.38.3 Validity of Permits to WorkValidity of Permits to Work– Main Hot Work (Naked Flame) Permits and Main Hot Work

Permits are valid for a period of one shift (12 hours) only. If work is to continue beyond one shift or the end of the shift, whichever is sooner, a new Permit must be issued

– No Main Hot Work Permit can be used, or remain in use, later than seven (7) shifts after the original PTW issue


SOUTH PARS

– Main Cold Work Permits are valid for a maximum period of seven (7) consecutive days, with revalidation required at every shift change. If for any reason it is necessary to specify a shorter time limit, this is to be noted in the ‘Valid Until’ section of the PTW

– The following three Complimentary Permits are valid for a period of one shift (12 hours) only. If the work is to continue beyond 12 hours or the end of the shift, whichever is sooner, a new Permit must be issued:

° Entry to Vessels or Confined SpacesEntry to Vessels or Confined Spaces° RadiographyRadiography° DivingDiving

– Complimentary Permits (High or Low Voltage Electrical Isolations) are normally valid for the duration of the related Main Work Permit. However, when the isolation is required for a longer duration than the Main Permit (e.g. when equipment is isolated for a major repair outside the Site, or when awaiting long term spare parts delivery), the Electrical Complimentary Permits may remain valid

– Under these circumstances, the Complimentary Permit is logged as a Long Term Isolation and remains in the Permit Office even though the associated Main Permit has bee cancelled


SOUTH PARS

8.48.4 Process/Mechanical IsolationsProcess/Mechanical Isolations• Safety polypropylene straps with plastic tag plates must be used

at each of the specified mechanical locking-off points where work is done under a Complimentary Permit (Process/Mechanical Isolations

• The unique numbers of both the Main and the Complimentary Permits must be clearly written on each of the tag plates, using a suitable indelible marker. On completion of the work and cancellation of the Permit, the straps may be removed and the tag plates wiped clean

• Long Term Isolations require locking-off

8.58.5 Gas TestsGas Tests • The persons responsible for conducting and monitoring Gas Tests

are the Gas Tester and the Safety Authority. Their roles and responsibilities are detailed in sub-sections 3.6 and 3.8


SOUTH PARS

Gas testing is required for:

• All Naked Flame and other Hot Work activitiesAll Naked Flame and other Hot Work activities• Electrical work in designated Hazardous areasElectrical work in designated Hazardous areas• Entry into Vessels or Confined SpacesEntry into Vessels or Confined Spaces

• A dedicated section is provided on the reverse side of the top white copy of each Main Hot Work (Naked Flame) and Main Hot Work Permit to record the resulta of any atmospheric sampling. This section must be completed by a nominated Gas Tester prior to such work commencing. Gas Tests must be repeated periodically throughout the validity of the Permit
