b) review and assessment of appropriate egress and ingress type and spacing; NOTE Excavations greater than 4 ft deep require additional considerations such as ladders, stairways, and ramps located within 25 ft maximum spacing to provide adequate means of ingress and egress. c) gas testing and monitoring requirements; NOTE 1 Excavations greater than 4 ft in depth require atmospheric testing to confirm oxygen deficiency or presence of hazardous atmosphere. NOTE 2 Access or continuous gas monitoring may be required depending on the location and type of repair work to be completed. 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. The initial monitoring of the area should be completed with full protective equipment as recommended by the Safety Data Sheet. A leak site area assessment should include the following additional steps. a) The area’s flammability level should be checked with a combustible gas indicator prior to entering site. Areas above 10 % of the lower explosive limit (LEL) should be declared hazardous and the personal exposure limit (PEL) determined. Access should be restricted. These areas should be further evaluated for proper PPE, ingress/ egress and work requirements.b) Toxicity testing should be made with direct reading instruments that may include colorimetric tubes. This toxicity testing determines the level of protective equipment required for the area. c) If a confined space is involved, such as a trench, always check for safe oxygen level. d) Personnel and equipment should not be permitted in the area until the hazard area has been defined and mitigation or entry plan developed. e) Restrict equipment and other ignition sources from the flammable hazard zone. f) If the hazard area extends into public areas, local authorities should be used to warn the public and to restrict access to the area. If public access is possible, suitable warnings should be posted. g) The leak site should be barricaded and marked to prevent the possibility of accidents and injuries. Consideration should be given to appropriate additional security measures to prevent spectators from entering the hazard area at any time. In addition, the following applies. 1) All personnel who enter the toxic hazard zone shall be equipped with proper protective gear (PPE). 2) All personnel leaving the toxic hazard zone shall be subjected to proper decontamination protocols prior to re- emerging into a toxic hazard free clean zone. NOTE Some leaks, according to their severity or hazards, may require compliance with the Occupational Safety and Health Administration’s (OSHA) Hazwoper Standard (29 CFR Part 1910.120).
