GAF Safety Procedures & Compliance 2 — Questions and Answers
Question 1: What is the minimum distance a worker must maintain from an unprotected roof edge when working without fall protection on a low-slope roof?
- 6 feet (Correct answer)
- 10 feet
- 15 feet
- 25 feet
Correct answer: 6 feet
OSHA requires workers to stay at least 6 feet from an unprotected roof edge when using a warning line system.
Question 2: Which OSHA standard specifically governs fall protection requirements for the construction industry, including roofing work?
- 29 CFR 1910.28
- 29 CFR 1926.502 (Correct answer)
- 29 CFR 1904.39
- 29 CFR 1910.132
Correct answer: 29 CFR 1926.502
29 CFR 1926.502 outlines fall protection systems criteria and practices for construction work.
Question 3: When must a Safety Data Sheet (SDS) be available to roofing workers on a job site?
- Only during initial training
- Only when requested by a supervisor
- At all times during work shifts (Correct answer)
- Only when hazardous materials are first delivered
Correct answer: At all times during work shifts
OSHA's Hazard Communication Standard requires SDS documents to be readily accessible to employees during their work shifts.
Question 4: What type of anchor point is required for a personal fall arrest system on a rooftop?
- Any fixed structural element
- An anchor capable of supporting at least 5,000 pounds per worker (Correct answer)
- A temporary hook rated for 1,000 pounds
- A ridge vent connection point
Correct answer: An anchor capable of supporting at least 5,000 pounds per worker
OSHA requires fall arrest anchor points to support at least 5,000 pounds per attached worker.
Question 5: Under GAF certification standards, how should roofing materials be stored on a roof to prevent overloading?
- Stack all materials at the ridge for easy access
- Distribute loads evenly and do not exceed the roof's load capacity (Correct answer)
- Place materials only on the strongest corner sections
- Store all materials along the eave edge
Correct answer: Distribute loads evenly and do not exceed the roof's load capacity
Materials must be evenly distributed and kept within the structural load capacity of the roof to prevent collapse.
Question 6: Which condition requires immediate work stoppage on a rooftop according to OSHA lightning safety guidelines?
- When thunder is heard within 30 minutes
- When lightning is visible within 10 miles
- When lightning is detected within 5–6 miles (thunder heard within 30 seconds of flash) (Correct answer)
- Only when rain begins falling
Correct answer: When lightning is detected within 5–6 miles (thunder heard within 30 seconds of flash)
The 30-30 rule states workers should seek shelter when the lightning-to-thunder interval is 30 seconds or less.
Question 7: What must a contractor do before allowing workers onto a roof that has been weakened by fire or water damage?
- Post a warning sign and proceed cautiously
- Conduct a structural assessment to confirm load capacity (Correct answer)
- Wear additional PPE and limit crew size to two
- Contact the manufacturer for warranty guidance
Correct answer: Conduct a structural assessment to confirm load capacity
A structural assessment must confirm the roof can safely support workers before any crew accesses a potentially compromised surface.
