4.16.1 Applying for a Permit - Boxes 1 to 3 4.16.1.1 Obtaining and Filling in Permit Forms

Departments/Contractors who apply for Permits will obtain the appropriate forms from Permit Issuing Points.

The Permit is divided into sections, called “boxes” in this Procedure. Where any box on a Permit form is not used, it shall have a line drawn through it. Boxes must not be left blank. Do not write information outside these boxes.

There are a number of tick boxes on the Permit (e.g. Haz Zone 0 ) to indicate area classification, gas test options etc. These are to be ticked with clear ticks  when required.

Permits must be completed in ball-point pen, to ensure that all copies of the Permit can be read easily. Pencil must not be used.

NO changes to the wording on a Permit are allowed. If changes are required, a new Permit must be raised. The only exception is correcting small mistakes, where the mistake is crossed out and the change initialled by the Performer and Approver.

Additions to the work scope are NOT ALLOWED under any circumstances. If an addition to the work scope is required, a new Permit is to be raised. It is at the Approver’s discretion whether an additional period of time is required before he authorises the new Permit and whether the additional work scope requires an additional site visit.

4.16.1.2 Box 1 - Application and Work Description Performer Details

The Performer can be the supervisor, the representative, or the chief of the team doing the work, or can be the single worker who performs the job. He is the one who pass through the permit application process.

The Performer will fill in the Boxes 1-3 of the Permit by entering the following information into the appropriate boxes:

Application and Work Description In Box 1 of the Permit, write:

 the location of the Work (e.g. “Compressor Station….”), the Worksite (the exact place in the Facility where the work is to be done; e.g. “Compressor no….”) and the exact equipment which is subject of the work (e.g. “Inlet valve on cylinder no…..”). In case the work is to be done outside the boundaries of a facility (eg: work on pipelines

Standard Annex 14

between facilities or between well and park, or works at well sites), the Location will be the name of the facility to whom the worksite belongs, or the downstream facility

 performer’s Name and signature

 for Contractors, the name of the Company

 the number of the Work Order ; this is very important, as it is used to link the permit to the daily working schedule

 the Hazardous Area Classification of the worksite (advice from the Approver/ Affected Area Responsible)

 whether the work involves working with naturally occurring radioactive materials (NORM) or in a NORM Restricted Area

 whether the work is in an H2S Facility (advice from the Affected Area Responsible) ; and, if known, the PPM (parts per million) figure of the maximum expected level

 the planned time for the work including preparation

 whether vehicle access to a Process Facility will be required

 the type of the area where the work is to be done

 The numbers of any Permits for other parts of the work (in the Associated Permit Numbers box). This will include any previous Permit for the work.

 a precise description of the work to be done, including the equipment to be worked on and tools to be used

 any special equipment to be used, especially if it may introduce a hazard

 the appointed fire watchman for the Hot Works ; this person must accept the task by signing and filling the date and time ; if the Performer cannot appoint one, the Approver must appoint a competent person

In case of Hot Works, two more sets of information shall be provided:

 measures to be taken by the Performer

 measures to be taken by the Affected Area Responsible

The Work Description must include enough information to allow Approvers to identify the hazards involved in the work and the Precautions necessary to control them.

NOTE : General description of the work will not be accepted (eg: Compressor repair”, or Well. roll-out”). The description must highlight the direct and effective intervention over the above mentioned equipment (Check inlet valve on cilinder no.”, or Replace coupling between driving engine and centrifugal pump..”)

A single Permit must not be used for a sequence of separate equipment where each equipment will be shut down, worked on and put back into service whilst the other equipment remain in service. This is to avoid confusion over isolations. The only exception allowed is work on electrical or electronic systems, such as lighting, which can be isolated and worked on in sequence.

Regulation Class Document Class

Standard Annex 14

NOTE : When a Permit is written for fault finding, it is important that the work description does not allow the work party to proceed with repair activities without the risks involved being assessed. The work description shall include:

 A description of the fault to be investigated.

 A description of the types of fault finding work that may be done.

 The point at which work should stop, so that a further Permit for the repair can be raised.

4.16.1.3 Box 2 – Certificates

The Performer shall attach the following certificates/documents to the Permits if they are required:

 Mechanical Isolation

 Electrical Isolation

 Confined Space Entry

 Excavation

 Additional Gas Test record

 Radiography

 Lifting Plans

The Performer shall tick the “√” column to show which Certificates are attached and, then, write the number of each certificate in the ‘Certificate Number(s)’

column.

NOTE : If more than one Permit is to be worked on within the same isolation boundary, the isolation for each permit is to be recorded separately on its Isolation Certificate. This will minimise the risk of an isolation being removed before all work is complete.

4.16.1.4 Box 3 - Gas Testing Requirements A Gas Test is required whenever:

 Hot Work is to be done in an area where hydrocarbons or other flammable gases/vapours may be present.

 Entry is to be made into a Vessel or other Confined Space.

 Work is at a place where toxic gases/vapours may be present.

 When a Gas Test is required, the Affected Area Responsible is to:

 Tick the gases to be tested for.

 Indicate the tests frequency, how often the test is to be repeated.

 State if continuous monitoring for gas is required during the work.

Standard Annex 14

NOTE : The requests regarding gas testing will be checked by the Approver. The Gas Test Results will be recorded separate in the Gas Test Record form (for Confined Space Entry will be recorded in the respective Certificate).

4.16.2 Authorisation and Co-ordination – Box 4 4.16.2.1 Box 4a and 4b - Authorizing the Permit

When Boxes 1-3 of the Permit have been filled in, the Performer is to take the Permit and Certificates to the appropriate Approver for Authorisation.

NOTE : Approvers require notice of a Permit to allow time to discuss the work and, for higher risk work, for examination of the worksite. For this reason, a good work planning is required (it is recommended that the work schedule to be prepared one day in advance). The Approver may allow shorter notice periods for essential unplanned work.

Before Authorising the Permit, the Approver must check that:

 The Permit received an unique number.

 All necessary information has been written in Boxes 1-3, and that the information can be understood easily.

 The Task Description is correct and sufficient for the work to be done.

 A JSA is attached and identifies all hazards that may affect the work, and the controls required to ensure that the work can be done safely. Extremely precautions must be taken in case of Hot Work

 The Isolations required have been identified in conjunction with the competent personnel (Affected Area Responsible and/or Authorised Electrical Person) and, where necessary, the Performer, and have been written on the Isolation

Certificate

 The need for any Isolation or other Certificates has been identified, and they have been attached to the Permit, with their numbers written in the Permit.

 Any gas testing requirements have been listed in Box 3 and are correct for the types of gas releases that might occur during the work.

 Measures taken by both performer and Affected Area Responsible are appropriate and comply with the controls required by JSA

If additional Preparations or Precautions are required, the Approver is to add them to the JSA and ensure they are agreed with the Performer.

If too many changes are needed to a Permit or other documents required for the work, the Approver may reject the Permit, and ask for a new one to be written. The Performer should be informed of what was wrong with the first Permit.

Regulation Class Document Class

Standard Annex 14

For Hot Work Permits, the Approver may consider to examine the worksite, normally with the Performer, to ensure the work is fully described on the Permit and that all safety aspects have been considered. For Cold Work Permits the Approver need not examine the worksite unless he considers this necessary.

Once he is satisfied that the Permit is correctly written for the work, the Approver is to set an Authorisation period for the Permit and to fill the box 4 (for cold work permits), respectively 4a (for hot work permits).

The Approver is then to write his name and position, and sign and date Box 4.

In case of Hot Works, the Performer is to take the Permit and Certificates to the appropriate Civil Fire Brigade for Authorisation. The Authorisation process is identical as described above.

For Hot Work permits, the Approver will fill and sign box 4a, the Civil Fire Brigade will fill and sign box 4b. Both authorisations are mandatory.

Once a Permit has been Authorised by the Approver, the only changes that can be made to it are the addition of new controls to the JSA. These changes are only to be made by the Approver or the Affected Area Responsible. Deletion of controls is not allowed. If any changes to controls are made, the Performer is to be informed.

The Performer is then responsible for ensuring that the rest of the work team, or himself, is fully briefed on the work content, precautions required and the requirements of the JSA.

NOTE : NO ONE MAY AUTHORISE A PERMIT FOR WORK THAT THEY WILL DO
