A crew will work from a slab edge that is 6 ft above the lower roof. Under OSHA construction rules, what protection trigger height applies to the unprotected side or edge?
Correct Answer
C) 6 ft
OSHA construction fall protection is generally triggered at unprotected sides and edges 6 ft or more above a lower level. Other choices confuse general industry, shipyard, scaffold, or unrelated thresholds.
Why This Is the Correct Answer
OSHA construction fall protection is generally triggered at unprotected sides and edges 6 ft or more above a lower level. Other choices confuse general industry, shipyard, scaffold, or unrelated thresholds.
Why the Other Options Are Wrong
Option A: 4 ft
In general project requirements, 4 ft is the wrong selection for Fall protection trigger height: 4 ft is the wrong OSHA fall-protection number for the item asked.
Option B: 5 ft
The trap in B is 5 ft. That selection is wrong because 5 ft is the wrong OSHA fall-protection number for the item asked.
Option D: 10 ft
Choice D (10 ft) is rejected because 10 ft is the wrong OSHA fall-protection number for the item asked.
Memory Technique
File fall protection trigger height under a inspection mark: condition first, number or duty second, answer 6 ft.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.501(b)(1) to confirm that OSHA construction fall protection is generally triggered at unprotected sides and edges 6 ft or more above a lower level.
