A roofing foreman checks the substrate condition: what trigger height applies to unprotected construction sides and edges?
Correct Answer
A) 6 ft or more above a lower level
6 ft or more above a lower level is the controlling requirement.501(b)(1). Other choices: the distractors are related-looking contract or field terms, but they do not match the cited requirement for review item 107.
Why This Is the Correct Answer
6 ft or more above a lower level is the controlling requirement.501(b)(1).
Why the Other Options Are Wrong
Option B: Apply the 4 ft limit to the fall protection check
In general project requirements, 4 ft is the wrong selection for Fall protection: 4 ft is the wrong OSHA fall-protection number for the item asked.
Option C: Treat 5 ft as the controlling fall protection result
The trap in C is 5 ft. That selection is wrong because 5 ft is the wrong OSHA fall-protection number for the item asked.
Option D: Base the fall protection response on 10 ft
Choice D gives 10 ft. Its specific error: 10 ft is the wrong OSHA fall-protection number for the item asked.
Memory Technique
File fall protection under a tag: condition first, number or duty second, answer 6 ft or more above a lower level.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.501(b)(1) to confirm that 6 ft or more above a lower level is the controlling requirement.501(b)(1).
