Can safety chains be used instead of a traditional guardrail system?

If a guardrail system is used as fall protection, it must meet the design, construction, and strength requirements outlined in 1910.29(b). Under new Subpart D, OSHA allows the use of safety chains for hoist areas, the warning lines of designated areas, and around the top of mobile ladder stands and platforms used for special applications. On the other hand, OSHA explicitly prohibits the use of chains at the top of fixed ladders now and says in the preamble to the final rule that, “safety chains are unsafe and do not provide the protection necessary to keep employees safe from falls.”

OSHA says that “equivalent” guardrail system members can be used, and 1910.29(b)(15) refers to using rope for top rails and mid-rails, so OSHA clarly allows flexible material as long as it meets the other requirements. If ropes or chains are used, a single safety chain is not allowed. A guardrail system — or the equivalent — must have both a top rail and midrail.
