Fall protection at six feet: OSHA's line in the air

29 CFR 1926.501 lists situations requiring fall protection — guardrails, safety nets or arrest systems — mostly from 6 feet (1.8 m), each with its own conditions.

Six feet is the number that recurs through OSHA's construction fall-protection standard — but 1926.501 works situation by situation, each with its own conditions. The core case: each employee on a walking/working surface with an unprotected side or edge which is 6 feet (1.8 m) or more above a lower level shall be protected from falling by the use of guardrail systems, safety net systems, or personal fall arrest systems.

The situations the standard names

• Leading edges: employees constructing a leading edge 6 feet or more above lower levels get the same three options — and only when those are infeasible or create a greater hazard may the employer fall back on a written fall protection plan.
• Hoist areas and holes: anyone in a hoist area, or working around holes including skylights more than 6 feet above lower levels, must be protected — covers, guardrails or arrest systems; an employee leaning through a hoist opening needs a personal fall arrest system.
• Formwork, ramps, excavations: the face of formwork or reinforcing steel and ramps and runways carry their own 6-foot rules; at the edge of an excavation 6 feet or more deep, guardrails, fences or barricades are required when the excavation is not readily seen — wells, pits and shafts at that depth are always protected.

And the threshold is not universal even inside the standard: employees working less than 6 feet above dangerous equipment must be protected from falling into or onto it — and other OSHA subparts set their own heights for other equipment and trades.

Protection is installed, inspected and logged

Guardrails up before the deck opens, covers marked and secured, harnesses inspected, anchor points verified: fall protection is a daily physical checklist with a paper trail — part of the same jobsite record as the daily report and the injury log. That safety record, kept per job, is what an ERP for construction companies runs, implemented per company around the way each one works.
