Giải thích
Scaffolds with platforms more than 7.5 feet above the level below generally require guardrail systems, or an equivalent approved fall-protection method, along open sides and ends. Option a relies on behavior instead of a physical safeguard. Option c omits the required top rail. Option d substitutes a warning line, which is not adequate edge protection on a scaffold. Complete guardrails prevent falls from the working platform.
