A worker on a residential roof installation is working 8 feet above the ground. According to Cal/OSHA fall protection requirements, what must the contractor provide?
Correct Answer
B) Fall protection system (guardrails, safety nets, or personal fall arrest)
Cal/OSHA Section 1669 requires fall protection at 7.5 feet or greater, so protection is required at 8 feet above ground.
Why This Is the Correct Answer
Cal/OSHA Section 1669 sets the fall protection threshold at 7.5 feet above a lower level for residential and general construction. Since 8 feet exceeds 7.5 feet, the contractor must provide a fall protection system—either guardrails, safety nets, or personal fall arrest systems (PFAS). This threshold is lower than federal OSHA's 6-foot trigger for residential construction.
Why the Other Options Are Wrong
Option A: No fall protection required under 10 feet
There is no Cal/OSHA exemption for heights under 10 feet. The California threshold is 7.5 feet, so at 8 feet the worker is already above the trigger point and protection is legally required.
Option C: Fall protection only required if slope exceeds 4:12
Roof slope does not determine whether fall protection is required—height above the lower level does. The 7.5-foot height threshold applies regardless of roof slope. Slope may affect the type of system used, but it does not eliminate the requirement.
Option D: Only safety training is required
Safety training alone does not satisfy Cal/OSHA's fall protection requirement. Physical protective systems (guardrails, safety nets, or PFAS) must be in place at 7.5 feet and above. Training is required in addition to, not instead of, physical protection.
Memory Technique
Remember '7.5 = Cal/OSHA's magic number' for fall protection on roofs and general construction. If you're above 7.5 feet in California, you need physical fall protection—no exceptions based on slope or distance.
