According to Cal/OSHA Title 8, Section 1670, at what height must fall protection be provided for employees working on low-slope roofs?
Correct Answer
C) 15 feet
Cal/OSHA Section 1670 requires fall protection for employees on low-slope roofs when working 15 feet or more above lower levels, which differs from federal OSHA's 6-foot requirement.
Why This Is the Correct Answer
Option C is correct. Cal/OSHA Title 8, Section 1670 sets 15 feet as the trigger height for mandatory fall protection on low-slope roofs (slope ≤ 4:12). This is a California-specific requirement that differs significantly from federal OSHA's 6-foot standard for roofing operations under 29 CFR 1926.502.
Why the Other Options Are Wrong
Option A: 10 feet
Option A is incorrect. 10 feet is not the Cal/OSHA threshold for low-slope roofs. It is a commonly referenced height in other contexts (e.g., scaffolding requirements) but is not the correct answer for low-slope roof fall protection under Section 1670.
Option B: 6 feet
Option B is incorrect. 6 feet is the federal OSHA (29 CFR 1926.502) threshold for roofing fall protection. California operates under its own Cal/OSHA standards, which for low-slope roofs set a higher threshold of 15 feet. Confusing federal and state standards is the most common error on this question.
Option D: 20 feet
Option D is incorrect. 20 feet is not specified in Cal/OSHA Section 1670 for low-slope roofs. It exceeds the actual 15-foot requirement and would leave workers unprotected at heights between 15 and 20 feet.
Memory Technique
Remember: California gives workers on LOW-slope roofs more room — '15 for low, 6 for feds.' The number 15 is 2.5× the federal standard of 6, reflecting California's distinct approach to low-slope roofing hazards versus steep roofs.
