Workers are installing roofing materials on a building with a 4:12 pitch roof. At what height above the lower level must fall protection be implemented?
Correct Answer
A) 6 feet
Even on low-slope roofs, OSHA requires fall protection when workers are 6 feet or more above a lower level. The roof pitch does not eliminate the 6-foot trigger height requirement.
Why This Is the Correct Answer
OSHA's fall protection standard (29 CFR 1926.501) requires fall protection systems when workers are exposed to falls of 6 feet or more above a lower level, regardless of roof slope. This 6-foot trigger height is a universal requirement that applies to all roofing work. The 4:12 pitch classification as a low-slope roof does not change this fundamental safety requirement. Fall protection must be implemented at 6 feet to protect workers from potentially fatal falls.
Why the Other Options Are Wrong
Option B: 15 feet
This is incorrect because OSHA requires fall protection on all roofs regardless of slope when workers are 6 feet or more above a lower level.
Option C: 4 feet
15 feet is too high and would leave workers unprotected in the dangerous 6-15 foot range where many serious injuries occur.
Option D: Fall protection is not required on low-slope roofs
4 feet is too low and not the OSHA-mandated trigger height for fall protection requirements in construction work.
Memory Technique
Use 'OSHA SIX-PACK' - OSHA's 6-foot rule is as standard as a six-pack, applying to roofing, scaffolding, and most construction work regardless of conditions.
