A contractor is preparing to work on a roof with a slope of 5:12. According to Cal/OSHA, what is the maximum roof slope that allows workers to forgo fall protection on low-slope roofs, provided the work is not near an unprotected edge?
- A5:12
- B3:12
- C4:12
- D6:12
Show answer & explanationAnswer & explanation
Correct answer: C. 4:12
Cal/OSHA defines a low-slope roof as one having a slope less than or equal to 4:12. On such roofs, fall protection is not required if work is not near an unprotected edge. A 5:12 slope would exceed this threshold and require fall protection.
Why the other options are wrong
- A. A 5:12 slope exceeds the Cal/OSHA definition of a low-slope roof for this exception and would require fall protection.
- B. This slope is considered low-slope and would not require fall protection under specific conditions, but it's not the maximum.
- D. A 6:12 slope is clearly a steep roof and would always require fall protection.
Cal/OSHA Low-Slope Roof Fall Protection Exemption
Fall protection may not be required on low-slope roofs (slopes 4:12 or less) if work is not performed near an unprotected edge.
- Applies to low-slope roofs
- Slope less than or equal to 4:12
- Work must not be near an unprotected edge
