H - VIOLATION OF SYSTEM SAFETY RULES Common violations of Transco’s System Safety Rules (SSR) by Competent Persons (CPs) include the following. Please remember that this list is indicative only and not exhaustive. 

CP not present on site while work is under progress through an open safety document. This is a major violation. The Competent Person must always be present on site supervising his/her working party for the period while the work is in progress through an open safety document.



CP receives more than one safety document. He may have finished his work; but as long the safety document is not cleared by him and cancelled by the relevant AP, he/she cannot receive another safety document.



CP receives safety document for work that is not covered by his existing competency. This includes both the project and nature of the work. It is responsibility of the CP not to apply and receive a safety document for works that are not covered by his competency.



CP takes on work that is not compatible with the work, equipment and location mentioned in the safety document. It has to be known that the CP is allowed to do only what is mentioned in the safety document. It is for this purpose that CP is expected to read and understand the safety document before signing (or receiving) it.

9


TRANSCO SSR - GUIDANCE BOOKLET Revision - 4, 2012 

CP receives a safety document that is inappropriately filled by the Authorized Person. The CP must read and understand safety document before receiving it, confirming all the details and fields of the safety document.



CP clears a safety document that has been received by another Competent Person. Please remember that safety documents are not transferrable under normal situations. Only in case of certain emergencies, to be established by the Authorized Persons, a safety document can be transferred from one CP to another (Transfer of Safety Document). This must follow a proper procedure as established by the SSR.



CP receives a safety document while his competency has expired or is in possession of an open safety document while his competency expired.



CP has not cleared a safety documents within the validity of the Safety Document as identified by the AP. CP must contact the AP before expiry of the validity in case if there is any requirement of extending the validity of the safety document.

PENALTIES The above mentioned violations are subject to penalty. Any competent person who is found to have conducted these violations WILL have his COMPETENCY WITHDRAWN immediately and will not be considered for competency again. There is zero tolerance to not complying; no matter how minor the violation may be. I - ACCESS TO SUBSTATIONS AND PUMPING STATIONS All Competent Persons accessing Transco substations and pumping stations for work purposes are required to follow certain code of personal and operational behavior. This code is explained in Transco SSR. Details of the code can be obtained from the Authorized Person who is issuing the safety document. The following, however, are some of the points that contractor CPs must be aware of and follow;  

  

   

Inform Load Despatch Centre (LDC or Control Person) whenever you access Transco Substation or Pumping Station for work purposes. Contact details can be obtained from the Authorized Person. Enter details of your work and safety document in the Substation or pumping station Log Book. In case of a manned pumping station, the shift operator/engineer may issue the safety document. CPs must ensure that the safety document details have been entered by the shift operator/engineer into the log book. Ensure that you keep the main door of the substation or pumping station locked all the times. Never leave a Transco substation unsecured. For access to rooms protected by automatic fire protection system, please ensure that the firefighting system has been switched to ‘Manual’ mode. On exit, switch it back to ‘Automatic’ mode ensuring that the door is left closed behind. All CPs accessing SS and PS for work purposes must familiarize themselves with the local Emergency Procedures. This involves the evacuation plan detailing the assembly points and the emergency exit. These procedures must be communicated to the working party during the TBT. Copy of the safety document must be posted appropriately at the work location and removed when work is done and safety document cleared. Only access work areas or locations/rooms inside the substation or pumping stations that are required according to the safety document. The minimum PPE requirement for access and work in a SS and PS (Safety Shoes, Safety Helmet, Coverall, and Hi-Vis Jacket) must always be fulfilled. Where two CPs are working at the same location, there must be a full coordination between them so as not to expose each other to the risks involved in their activities. 10
