1 SSR Competency Assurance Guidance Booklet No.2 (SSR Summary for Contractors CP) Revision 0 October 2014 HSEQ Department, TRANSCO Disclaimer: This document is for general guidance and awareness purposes only and therefore should not be considered as a replacement of Transco SSR

2 A - SUMMARY OF SSR The following information is an extract from Transco SSR Revision 3.0. The contractors Competent Persons need to comprehend the following as a minimum requirement and to pass the written exam and interview. PRINCIPLES OF SSR 1. System Safety Rules are intended to protect persons from inherent system hazards 2. Only Competent Persons can undertake works in TRANSCO premises after receiving a Safety Document (SD) 3. Authorized Person (AP) assesses all risks & applies System Safety precautions before issuing the SD. 4. Equipment must be clearly identified in SD (matching equipment label on site) 5. Operation of equipment is by direct communication; operation by prearranged signals or timing is not allowed. 6. Competent Person (CP) must be present on site all time during work, controlling all activities & persons. (This is called Principle of Supervision) 7. Safety Document must be retained by the CP on site. GENERAL DEFINITIONS Hazards Safe System System Hazards System Safety General Hazards General Safety Release of Energy Key Safe Key High Voltage (HV) PPE Receipt Clearance LDC Isolation Point Primary Earth Additional Earth Toolbox Talks Source of dangers to persons (for example tools & equipment is a hazard). Free from Hazards Equipment interconnected in a network (Power/Water/Telecom Networks) Hazards present (inherent) in a system (Electrical, Mechanical, Chemical, Pressure) Precautions to control system hazards, applied by an Authorized Person Example: Isolation, earthing, safety document, safe method of work, applying demarcation, danger / caution notices, labeling, venting, draining, purging & release of stored energy, PPE Non system Hazards like excavation, lifting, scaffolding, ladders, hot works, etc. Precautions to control non system hazards, maintained by a Competent Person Example: Shoring, barriers, training, supervision, approved procedures, safe method of work, inspection of certificates tools &equipment, on site risk assessment, toolbox talks, PPE etc. Means venting, draining, purging, or braking, or spring release. A unique Key for locking the Key Safe at work location, given to CP by the AP A voltage exceeding 1000 volts Personal protective equipment (helmet, safety shoes, gloves, coveralls, high-vis etc.) Means that CP has agreed that he/she fully understands the work and is satisfied of applied system safety precautions and accepts full responsibility to maintain the safety and supervise the work. Means a declaration by the CP that all persons, materials & tools are removed from the work area and it is no longer safe to work within that area. Load Dispatch Center The point at which equipment is isolated to provide physical separation from live network. Conductor that protects from accidental operation while working on HV equipment (min. 95 mm 2 ) Conductor that protects from induced voltage while working on HV equipment. (Min. 25 mm 2 ) An onsite communication between the CP and his/her working party before the start of work conducted each day early in the morning.

3 Earthing Schedule Safety Clearance hazards, control measures, emergency procedures, working environment, any changes from previous day, check PPE and tools. A schedule indicating the additional earth requirements for each stage of the work necessary to control induced voltages as circumstances change The distance from the nearest exposed HV conductor not earthed, or from an insulator supporting an exposed HV conductor, which must be maintained at all times to avoid danger to persons. 5.5m for 400kv, 4m for 220kv, 3m for 132kv, 1.5m for all HV conductors up to 33kv, (Note: HV insulators minimum safety clearance distance= 0.5m) DEFINITION OF AUTHORITIES Competent Person Authorized Person Control Person A competent person (CP) is a person, having suitable & sufficient technical Knowledge & experience to recognize and avoid danger, use safe method of works & use appropriate PPE, receives & clear SD. An authorized person (AP) is a Transco competent person who has been additionally authorized to Issue & cancel Safety documents, assess all work risks and apply system safety precaution before start of any work. A control person (CN) is a Transco employee who controls the transmission system (from LDC) & coordinates system safety activities. SAFETY DOCUMENT PROCEDURE 1. Please note that the CP should be in possession of only one SD at any point of time. 2. CPs should not proceed with any works at any time if they are unsure or in doubt about any aspect of the work. They must STOP AND CONTACT THE AP IMMEDIATELY. No Person Actions 1 Contractor Apply to Transco concerned department 2-7 days before the start of intended works using Application For Work (AFW) form (available with concerned department Transco) with Work Method Statement, Competency Certificate of the CP and any other related documents as required at the time of application. 2 Transco Concerned department review application for work & submit to LDC for approval. 3 Transco LDC approves application for work & return to the concerned Transco department. 4 Authorised AP from the concerned department shall asses all the risks on site, apply System Safety precautions, and issue Safety Document to the contractor Competent Person after obtaining consent from a Control Person in LDC. 5 Competent Read, understand and check the SD before receipt. Conduct toolbox talks, start the work & maintain general safety. CP must follow and only do the works as mentioned in the SD, follow method statement, supervise 100% of the time. NEVER PROCEED IF YOU ARE UNSURE OR IN DOUBT, always contact AP for help, advice and clarification. 6 Competent CP gives clearance after completion of work & removal of persons, tools from work location. Transco site supervisor must be informed before giving clearance. 7 Authorised AP cancel the SD after inspecting the work area. TYPES OF SAFETY DOCUMENT (Only three in Transco) Permit to Work (PTW): A safety document for works requiring secured isolation followed by Earthing or Release of stored energy. Limited Access Permit (LAP): A safety document where safety from the system is achieved by applying limits to work and/or work area. See the LAP form in Section-J. Sanction for Test (SFT): A safety document for works requiring injection of high voltage or current and which may require the removal of primary earths. All PTW must be cancelled first. 3 This Document is for General Guidance only By HSEQ Department, Transco

4 SAFE WORK AREA (Prepared by the Authorized Person) Red & white tape or chain Lock Lock Earth Earth Isolation Point All equipment outside Safe Work Area are considered LIVE! Isolation Point The limits of Safe Work Area must be physically identified by Red & White tape or chain with Danger notices displayed at the limits, facing into the Safe Work Area (inside). Work is not allowed on an established isolation point SOME PICTURES AND A SCHEMATIC SAFETY KEY DANGER NOTICE CAUTION NOTICE MINIMUM SAFETY CLEARANCE DISTANCE HV Insulator HV conductor 5.5 meter Safety-Key is locked inside key-safe by 1 Control-Key and 4 key-safe-keys Displayed facing into the Safe Work Area Used to identify Points-of-Isolation 400kv OHL safety clearance distance measured from HV conductor 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, understand and check the safety document before signing (or receiving) it. 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. 4 This Document is for General Guidance only By HSEQ Department, Transco

5 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. Transco SS and PS are periodically patrolled by contracted Security Staff. All CP must reproduce the SD and their identity upon enquiry. 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. 5 This Document is for General Guidance only By HSEQ Department, Transco
