A construction site has employees working at heights of 12 feet above the ground on a steep-slope roof. According to Cal/OSHA fall protection requirements, what must be provided?
Correct Answer
D) Personal fall arrest system, guardrail, or safety net
Cal/OSHA requires fall protection (personal fall arrest system, guardrails, or safety nets) for work on steep-slope roofs at 6 feet or more above lower levels.
Why This Is the Correct Answer
Cal/OSHA requires fall protection for employees working on steep-slope roofs at 6 feet or more above lower levels. At 12 feet, workers must be protected by one of three acceptable methods: personal fall arrest systems (harnesses and lanyards), guardrail systems, or safety net systems. These are the only approved fall protection methods for steep-slope roofing work under Cal/OSHA regulations.
Why the Other Options Are Wrong
Option A: No protection required at this height
This is incorrect because Cal/OSHA mandates fall protection for steep-slope roof work at 6 feet or more above lower levels. At 12 feet, protection is absolutely required, not optional. The 6-foot trigger height is well-established in Cal/OSHA fall protection standards.
Option B: Safety monitoring system only
Safety monitoring systems alone are insufficient for steep-slope roofing work. While monitoring systems may be used in conjunction with other methods, Cal/OSHA specifically requires personal fall arrest systems, guardrails, or safety nets for steep-slope roofs. Monitoring alone does not provide adequate protection.
Option C: Warning line system only
Warning line systems alone are not adequate for steep-slope roofing work under Cal/OSHA. Warning lines are typically used for low-slope roofs in combination with other protection methods. For steep-slope roofs, the regulation specifically requires personal fall arrest systems, guardrails, or safety nets.
Memory Technique
Remember 'Six Steep Steps': At 6+ feet on steep slopes, you need the 'Big Three' - Personal fall Arrest, Guardrails, or Safety nets. These are the only three acceptable protection methods for steep-slope roofing work.
