Miller Confined Space & Rescue

In plain words. Fall protection is sold by part: a harness you wear, a lanyard or self-retracting lifeline that connects you, and an anchor that holds the system to the structure. OSHA 1926.502 requires an anchorage able to hold 5,000 pounds per worker (or a system designed by a qualified person with a safety factor of two), limits the arresting force on a worker to 1,800 pounds, and limits free fall to 6 feet. ANSI/ASSP Z359 is the voluntary standard most manufacturers test to; the capacity range printed on the label (usually 130 to 310 pounds, including tools) is the range the equipment was tested for.

Technical. ANSI/ASSP Z359.11 covers full body harnesses, Z359.13 energy-absorbing lanyards (6 ft and 12 ft free-fall versions), Z359.14 self-retracting devices (Class 1 overhead anchorage, Class 2 rated for foot-level anchorage and leading edge, 2021 edition), Z359.18 anchorage connectors, Z359.1 the overall code; ANSI/ISEA 121 covers dropped-object prevention (tool tethers and attachments); ANSI A14.3 covers fixed ladders. OSHA 29 CFR 1926.502 (construction) and 1910.140 (general industry) set the anchorage strength, arresting force, free-fall and inspection requirements.
