Electrical Isolation Keys:
A Key Safe shall be employed to control all the Safety Padlock keys used to secure an Isolation. The Key Safe shall be
fitted with at least two unique locks with associated keys. Where the electrical isolation requires the use of a Key
Safe then the Key Safe keys should be distributed as follows:
Key 1 – Permit Holder
Key 2 – Senior or Authorized Electrical Person (SAEP or AEP)
Key 3 (If fitted) – Area Authority or SAEP/AEP
•
•
•
Overhead line clearance:
•
PR-1242 – Activities in the Vicinity of Overhead Power Lines gives required horizontal & vertical clearances
(Typically, 3m both horizontally and vertically)
•
•
A clearance certificate is required to be authorised by the Asset Custodian.
An 'Overhead Line Clearance ', is required for passing by or under an overhead line. A PTW is required as this
is not an Electrical Safety document.
If work is to be conducted under or near an Overhead Line a 'Limitation of Access' with supervision by a
Competent Electrical Person may be required.
If machinery could possibly come into contact with the Overhead Line, a PTW is required (Activity 9.1).
•
•
Electrical safety rules and PTW interfaces:
:Electrical safety documents
There are five electrical safety documents:
1. Electrical PTW - For HV work or LV with Circuit Main Earth (CME)
2. Sanction for Test - For HV work
3. Limitation of Access - For HV and LV work
4. Electrical Isolation / De-Isolation Certificate - For HV and LV work
5. Electrical Immobilisation Certificate - LV isolation for Non-Electrical work
The Electrical Safety Document highlights the electrical hazards of the relevant electrical work but additionally
the work also requires a Class A or B PTW relevant to the activity when the work interfaces with other
work/operations. This is to control the additional hazard at the interface.
Types of electrical work:
Work in electrical areas of a production asset
The work shall be authorised by the Area Electrical Supervisor (licensed as a Responsible Supervisor) and agreed
by the Production Responsible Supervisor as the Other Affected Custodian and validated by the Electrical Area
Authority. If however the work extends or affects equipment outside the substation then a PTW authorised by
the Production Responsible Supervisor is required.
This includes work in sub-stations and switchyards located in production assets.
Electrical work on electrical assets controlled by power systems operations
The work shall be authorised by the Infrastructure Electrical Supervisor (licensed as a Responsible Supervisor), no
other Affected Custodian and validated by the Electrical Area Authority.
Non electrical work on electrical assets controlled by power systems operations
The work shall be authorised by the Infrastructure Electrical Supervisor (licensed as a Responsible Supervisor), no
other Affected Custodian and validated by the Electrical Area Authority, or he is not available validated by a
Production Area Authority who is an Electrically Appointed person.
Live line washing
Requires only a Limitation of Access (LOA) unless the live lines pass through a hazardous zone (1 or 2) where it
needs a Class B PTW.
The Electrical Supervisor shall ensure that the auto-reclose facility is disabled.

Work at remote electrical assets controlled by power systems operations
•
•
•
•
•
•
Electrical work will have a suitably qualified electrical person in the work party to validate the PTW.
Non-electrical work - e.g. work on gas turbine prime mover is covered by 11.9.2 above, unless
circumstances prevent the PDO Electrical Area Authority from validating in which case the PTW can be
validated by a suitably qualified Production Area Authority from the local area. This requires agreement
from the asset teams and a familiarisation briefing for the Area Authorities.
• If the asset team or project team working within an Asset wish to maintain construct or commission
plant under custodianship of UIE3 then they need to do so under the PDO PTW system. If asset
operations wish to carry out work on utility equipment inside a power station fence the following shall
be followed:
Operations Responsible Supervisor shall authorise the PTW.
The PTW Applicant shall fax a copy of the PTW to the relevant Power System Responsible Supervisor in Yibal,
who will sign the faxed copy as Affected Custodian.
The PTW shall be faxed back to the PTW Applicant for him to arrange for the Operations Responsible
Supervisor to sign the actual PTW in box 5, by writing the words “signed on behalf of” and writing in the
name of the Affected Custodian.
The signed fax copy should be attached to the worksite copy of the actual PTW as an auditable record of the
agreement.
When Power Systems wish to carry out any physical work within the fenced area, a PTW should be raised by the
Power Systems Responsible Supervisor and countersigned by the Operations Responsible Supervisor as Affected
Custodian.
For daily validation within an area under the control of Power Systems this can be completed by fax under strict
adherence to the following conditions.
•
•
The Power Systems Area Authority shall visit the site for the first validation and at least once per week for
ongoing activities where the task or risks have not changed.
Subsequent validations can be completed by fax in the following way.
o
o
o
o
o
o
1.1.1
The Permit Holder emails/faxes the PTW to the Area Authority, who signs the scanned copy in box 10,
and returns it to the Permit Holder by email or fax.
The Permit Holder attaches the signed copy to the worksite copy.
On suspension of the activity on a daily basis, the Permit Holder emails/faxes the suspension in box 10
to the Area Authority.
The process is repeated when validation is again required.
The worksite copy of the PTW will therefore contain a signed copy of box 10 for each day the PTW was
validated.
On completion or cancellation, the PTW is emailed/faxed to the Area Authority who shall visit the site
with the Permit Holder and check the worksite has been left safe and tidy and close/cancel the PTW.

1.2.1
Pre-requisites for ESP activities
The following shall be in place:
•
•
•
•
•
The Contract Holder (CH) shall ensure the competency of vendor engineers assuring their competency
credentials and certificates.
The Contract Site Rep (CSR) shall ensure that all controls in the HEMP exercise and the Job HSE plan in place.
The CH shall ensure every activity has a robust safe execution procedure.
The CSR with the Production Coordinator and vendor shall establish Job HSE Plans for every specific activity
for ESPs, ESPCPs & PCPs in their area using the Online Job HSE Plan system as baseline.
The Job HSE Plans shall be readily available to the CSR, Production Coordinator/Supervisor and vendor.
The following steps shall be adhered to for all ESPs, ESPCPs & PCPs activities:
1. The Responsible Supervisor requests the CSR to attend job.
2. The CSR instructs the vendor engineer to carry out the work (this does not have to be face to face) and to
refer to relevant Job HSE Plan for the activity and verify all controls are in place.
3. Vendor engineer informs CCR when the job is started.
4. The CCR Operator logs the work details and start time in the “Station Log Book” and reports the status to the
Responsible Supervisor.
5. Vendor engineer informs CCR when the job is completed.
6. The CCR Operator logs the work details in the “Station Log Book” including the completion time and reports
the status to the Responsible Supervisor.
7. Vendor engineer submits Job HSE Plans for all completed jobs to the CSR for documentation and assurance
on return to the base.
