According to OSHA, what is the maximum height a worker can be above a lower level while working on a flat roof before fall protection is required?
Correct Answer
B) 6 feet
The standard 6-foot rule applies to flat roofs. Workers must be protected from falls when working 6 feet or more above lower levels, regardless of the type of roof surface.
Why This Is the Correct Answer
OSHA's general industry standard 29 CFR 1926.501(b)(10) establishes that fall protection is required when workers are 6 feet or more above a lower level on flat roofs. This is part of OSHA's universal 6-foot rule that applies to most construction work situations. The rule is designed to prevent serious injuries and fatalities from falls, which are one of the leading causes of workplace deaths in construction. This standard applies regardless of the roof surface type - whether it's flat, low-slope, or other configurations.
Why the Other Options Are Wrong
Option A: 4 feet
4 feet is too low and does not meet OSHA's established threshold for fall protection requirements on flat roofs.
Option C: 8 feet
8 feet exceeds OSHA's requirement and would leave workers unprotected in dangerous situations between 6-8 feet.
Option D: 10 feet
10 feet is far too high and would expose workers to significant fall hazards without required protection.
Memory Technique
Think 'Six feet, safety net' - the number 6 rhymes with 'fix' which reminds you to fix safety issues at 6 feet and above.
