In addition, observe the following general falls/ladders procedures and practices: • CB&I requires 100% fall protection when ascending, descending, or working from ladders with a potential fall of 6ft (1.8.m) or more. The specific requirements for implementation are found in CMS-710-02-PR-00900(Fall Protection).Use Type I rated ladders. • Make sure ladder rungs are sturdy and free of cracks. • Use ladders with secure safety feet. • Pitch ladders at a 4:1 ratio. • Secure ladders at the top or have another person at the bottom to help stabilize it. • Ladders used to access an upper landing surface shall extend at least three feet above the upper landing surface. • Do not use ladders for access to air stripper towers above six feet. Instead,use aerial lift. • Use non-conductive ladders near electrical wires. • The top step of a stepladder should not be used as a step. • Do not carry any object or load that could cause a loss of balance or a fall. • All ladders need to be inspected using the CB&I ladder Inspection Form(CMS-710-02-FM-00501) (Appendix A) Heavy Equipment Operations Observe the following heavy equipment operations procedures and practices: • All equipment operators will hold a valid Equipment Operator Wallet Card in conformance with CMS-710-02-PR-02800 • Wear leather gloves while attaching support members to protect against pinching injuries. • While working from elevated levels greater than six feet, ensure that all employees have 100% fall protection with full body harnesses and guardrails. Do not stand under loads that are being raised or lowered with cranes or aerial lifts. • The subcontractor or CB&I Operator must conduct pre-operational inspections of all equipment. In addition, daily inspections will be conducted on the equipment prior to site activities. • Maintain appropriate distance from overhead utilities: - Maintain at least 10 feet from overhead power lines, up to 50 kV - For voltages over 50 kV, add 0.4 inches per kV to obtain the safe distance between equipment and power lines. - If voltage is unknown,remain at least 20 feet from overhead power lines. • Always stay out of the swing radius of all heavy equipment. Always use a spotter during movement of equipment. The spotter and others, as appropriate, shall maintain constant communication with the operator. • All operators must have adequate training and be qualified to operate the particular heavy equipment unit. 5-4
