CSLB C-46 Solar ContractorSafetyMedium
A solar crew is installing modules on a commercial building with a roof height of 25 feet. The roof has a low-slope (less than 4:12 pitch) and the work is being performed within 6 feet of the roof edge. Which of the following fall protection methods is required by Cal/OSHA?
- AGuardrail system, safety net system, or personal fall arrest system
- BWarning line system with a safety monitor
- CNo fall protection is required if workers are experienced
- DSafety monitor system only
Show answer & explanationAnswer & explanation
Correct answer: A. Guardrail system, safety net system, or personal fall arrest system
For low-slope roofs (less than 4:12 pitch) with work performed within 6 feet of the edge, Cal/OSHA requires conventional fall protection methods: guardrail systems, safety net systems, or personal fall arrest systems. Warning line systems with a safety monitor are permitted only when work is performed between 6 and 15 feet from the edge.
Why the other options are wrong
- B. A warning line system with a safety monitor is typically allowed for work between 6 and 15 feet from the edge, not within 6 feet.
- C. Experience does not exempt workers from mandatory fall protection requirements.
- D. Safety monitor system alone is generally not sufficient for work within 6 feet of the edge.
Cal/OSHA Low-Slope Roof Fall Protection (Within 6 ft)
Cal/OSHA requirements for fall protection when working on a low-slope roof (less than 4:12 pitch) within 6 feet of the roof edge.
- Applies to low-slope roofs (less than 4:12 pitch).
- Mandates conventional fall protection: guardrails, safety nets, or personal fall arrest systems.
- Warning lines with safety monitors are not sufficient for this proximity to the edge.
Memory trick: Six feet close, conventional safety you must propose.
