GAF Safety Procedures & Compliance 3 — Questions and Answers
Question 1: Which class of hard hat is required when electrical hazards are present on a roofing job site?
- Class A
- Class B (Correct answer)
- Class C
- Class G
Correct answer: Class B
Class B hard hats provide the highest level of electrical insulation, protecting against high-voltage conductors.
Question 2: What action must a GAF-certified contractor take when a worker is found without required PPE on an active job site?
- Issue a verbal reminder and document it at end of day
- Remove the worker from the hazardous area immediately until compliant (Correct answer)
- Allow the worker to finish the current task before correcting
- Notify the building owner and continue work
Correct answer: Remove the worker from the hazardous area immediately until compliant
Workers must be removed from hazardous areas immediately when not wearing required PPE to prevent injury.
Question 3: What is the maximum wind speed at which most roofing manufacturers, including GAF, recommend halting shingle installation?
- 10 mph
- 20 mph
- 25 mph (Correct answer)
- 35 mph
Correct answer: 25 mph
Wind speeds above 25 mph can cause shingles to flutter, crack, or fail to lay flat, and pose worker safety risks.
Question 4: According to OSHA, how often must portable ladders used on roofing sites be inspected?
- Monthly by a qualified inspector
- Before each use (Correct answer)
- Annually by the manufacturer
- Only after a visible incident or drop
Correct answer: Before each use
OSHA requires portable ladders to be inspected before each use to identify defects that could cause failure.
Question 5: What is the correct way to carry materials up a roof ladder to maintain three-point contact?
- Carry all materials in both hands while climbing
- Use a tool belt or hoist system so hands remain free (Correct answer)
- Have another worker push materials from below
- Attach materials to your back with bungee cords
Correct answer: Use a tool belt or hoist system so hands remain free
Three-point contact requires two hands and one foot (or two feet and one hand) on the ladder at all times, so materials must be carried by other means.
Question 6: Under OSHA's heat illness prevention guidelines, when must employers provide shade to outdoor workers in hot weather?
- Only when the heat index exceeds 103°F
- When workers request it
- Whenever working conditions are hot enough to cause discomfort
- When the heat index exceeds 80°F (Correct answer)
Correct answer: When the heat index exceeds 80°F
OSHA's heat illness prevention guidance recommends providing shade access when the heat index reaches 80°F or higher.
Question 7: What is the purpose of a Job Hazard Analysis (JHA) before starting a roofing project?
- To estimate material costs and labor hours
- To identify, assess, and control hazards specific to each task (Correct answer)
- To assign worker roles and shift schedules
- To document completed OSHA training records
Correct answer: To identify, assess, and control hazards specific to each task
A JHA systematically identifies hazards for each work task and establishes controls before work begins.
