4 Preliminary Knowledge 4.1 Personnel Qualified oversight is a prerequisite to the successful implementation of pipeline repair practices. Regulatory requirements for the qualification of pipeline personnel performing repair activities are covered in DOT Regulation 49 CFR 195.501 through 195.509 of Subpart G (Operations and Maintenance). Guidance for the development and implementation of operator qualification (OQ) programs and procedures are given in ASME B31Q, Pipeline Personnel Qualification, and in API 1161, Guidance Document for the Qualification of Liquid Pipeline Personnel. Personnel working on pipeline repairs must understand the importance of careful planning to ensure safe and efficient practices and procedures. Employees and contractors should be briefed on-site about specific repairs and safety procedures. Only personnel with the proper training, experience and demonstrated skills should be allowed to perform pipeline repairs. 4.2 Safety Procedures Repair personnel shall have a basic knowledge of safety procedures that includes, but is not limited to, lockout/tagout (LOTO); confined space; worker’s right-to-know; personal protective equipment; excavation and trenching; fire prevention and protection; emergency response; atmospheric testing devices; hot work; work permitting; respiratory protection; hydrogen sulfide; hearing conservation; first aid; hazardous substances; fall protection; ergonomics; electrical hazards; and abrasive blasting; Regulations to protect worker safety are covered in OSHA 29 CFR 1910 (operations) and 29 CFR 1926 (construction). The company person or designee with overall responsibility for the repair should review previous testing and repair files to determine the presence or absence of asbestos-containing pipe coatings, lead-based paint, or other substances requiring special attention.
In addition, the company person or designee with overall responsibility for the repair should be knowledgeable about the most recent Department of Transportation Alert Notices and National Transportation Safety Board recommendations related to pipelines as they may pertain to the specific repair situation. 5 Pre-departure Practices 5.1 General When piping revisions, replacements, or repairs are needed, the goal is to safely and efficiently complete the work. Work shall include in-service and out of service repairs. To ensure the safe and efficient completion of the repair project, the proper preplanning and groundwork shall be accomplished before any work is done. 5.2 Preplan Procedures The preplan should include the following steps. a) Consult and comply with all applicable laws and regulations. b) Notify “ONE CALL” service, if provided in the area or, if not, contact the owners of the buried facilities directly, giving notice of the work and allowing ample time for other buried facilities to be located and marked. (811 National One Call number.) c) Evaluate reported damage and determine if a Safety-related Condition Report should be filed with the Department of Transportation.
d) excavation requirements, inclusive of sheeting and shoring design implementation requirements; — Excavations less than 5 ft deep shall require inspection and documentation by a competent person. NOTE Appropriate sloping may be required as a result of the competent person evaluation. — Excavations greater than or equal to 5 ft deep shall require sloping, sheeting or shoring protection to mitigate the potential of trench wall collapse. The appropriate sloping, sheeting or shoring technique used shall be determined based upon soil conditions, as assessed by a competent person. Refer to OSHA Safety and Health Regulations for Construction, 29 CFR Part 1926.652, for specific excavation safety regulatory requirements. e) confined space analysis, if required; — Appropriate personnel safety control, monitoring and retrieval systems shall be available prior to initiating any work within a confined space. f) equipment status and energy control requirements, i.e. lockout/tagout (LOTO) or specific product isolation; — Control information and requirements should be reviewed and documented prior to work initiation. NOTE A project may require a system walk through and review to ensure system status and control is adequate for work intended. g) personal protective equipment (PPE) requirements to complete the job safely; h) miscellaneous safety requirement considerations such as fire watch, ventilation, bonding/grounding, signage, and barricades. 6.3 Leak Site Area Assessment Procedures If a repair is required because of damage that has resulted in a product release or the product has spilled during the repair, additional site specific hazard assessments shall be performed. This hazard assessment should result in a worksite safety plan. A hazard zone should be established by determining the amount of hydrocarbon vapors in the area. Information that is contained in the Safety Data Sheet shall be consulted to determine the material’s volatile and toxic characteristics.
