OSHA 10-Hour Construction ReviewScaffoldsMedium
A worker is performing tasks from a supported scaffold. The scaffold is equipped with a guardrail system, but some sections of the guardrail have been temporarily removed to allow for material handling. What additional fall protection measure must be implemented for workers exposed to the fall hazard in these areas?
- AA controlled access zone
- BA safety monitor to alert workers of the hazard
- CA warning line system around the exposed area
- DA personal fall arrest system (PFAS)
Show answer & explanationAnswer & explanation
Correct answer: D. A personal fall arrest system (PFAS)
Whenever guardrail systems are temporarily removed for tasks like material handling, OSHA requires alternative fall protection. A personal fall arrest system (PFAS) is the most common and effective alternative to protect workers from falls through the openings created by the removed guardrail sections.
Why the other options are wrong
- A. Controlled access zones are generally used for leading edge work or overhand bricklaying, not as a direct fall protection for scaffold openings.
- B. A safety monitor alone is not considered adequate fall protection for scaffold work where guardrails are removed.
- C. Warning line systems are typically for roof work, not as a primary fall protection on scaffolds when guardrails are removed.
Temporary Guardrail Removal
When scaffold guardrails are temporarily removed, alternative fall protection must be immediately implemented to protect workers.
- Common reason for removal: material handling.
- PFAS (Personal Fall Arrest System) is the primary alternative.
- Fall protection must be in place before guardrail removal.
- Guardrails must be replaced as soon as the task is complete.
