CSLB General Building (B)SafetyEasy
A contractor is installing roofing shingles on a residential building. The roof has a 6:12 slope and the eaves are 12 feet above the ground. Which of the following fall protection methods is acceptable according to Cal/OSHA for this scenario?
- ANo fall protection required as it's residential construction.
- BSafety monitor system only.
- CWarning line system only.
- DPersonal fall arrest system.
Show answer & explanationAnswer & explanation
Correct answer: D. Personal fall arrest system.
For a roof with a 6:12 slope and fall distance over 7.5 feet, Cal/OSHA requires conventional fall protection methods such as a personal fall arrest system, guardrail system, or safety net system. Warning lines and safety monitors are generally not sufficient alone for such slopes and heights.
Why the other options are wrong
- A. Fall protection is required for residential construction when fall hazards exceed 7.5 feet or slopes exceed 4:12, regardless of construction type.
- B. A safety monitor system alone is generally not permitted for slopes greater than 4:12 or fall distances exceeding 7.5 feet.
- C. A warning line system alone is typically insufficient for a 6:12 slope and 12-foot fall distance.
Cal/OSHA Fall Protection Methods
Cal/OSHA mandates conventional fall protection (guardrails, safety nets, PFAS) for fall hazards over 7.5 feet or roof slopes greater than 4:12.
- Conventional methods are preferred.
- PFAS is a common and effective method.
- Warning lines/safety monitors have limited application.
Memory trick: Fall protection is 'Guard-Net-Arrest' for serious falls.
