ASP ASP Construction Safety and Fall Protection 4 — Questions and Answers
Question 1: Under OSHA 29 CFR 1926.502, what is the maximum free-fall distance allowed when using a personal fall arrest system (PFAS)?
- 3 feet
- 4 feet
- 6 feet (Correct answer)
- 10 feet
Correct answer: 6 feet
OSHA limits free fall to 6 feet when using a personal fall arrest system on construction sites.
Question 2: A worker is performing roofing work on a low-slope roof (slope ≤ 4:12). Which of the following is NOT an acceptable fall protection method under OSHA 1926.502?
- Safety net system
- Warning line system alone with no other controls (Correct answer)
- Personal fall arrest system
- Guardrail system
Correct answer: Warning line system alone with no other controls
A warning line system alone is not acceptable for low-slope roofs; it must be used in combination with a safety monitoring system or guardrails.
Question 3: What is the minimum breaking strength requirement for a safety net used as fall protection on a construction site?
- 2,500 lbs
- 5,000 lbs
- 17,500 lbs (Correct answer)
- 25,000 lbs
Correct answer: 17,500 lbs
OSHA 1926.502(c) requires safety nets to have sufficient strength to absorb an impact force of 17,500 ft-lbs minimum.
Question 4: During scaffold erection on a construction site, at what height must workers be protected from falls?
- 4 feet
- 6 feet
- 10 feet (Correct answer)
- 15 feet
Correct answer: 10 feet
OSHA 1926.451 requires fall protection for scaffold workers at heights greater than 10 feet above a lower level.
Question 5: A contractor is using a leading edge fall protection system. The anchorage point for the PFAS must be capable of supporting at least:
- 2,000 lbs per worker attached
- 3,600 lbs per worker attached
- 5,000 lbs per worker attached (Correct answer)
- 10,000 lbs per worker attached
Correct answer: 5,000 lbs per worker attached
OSHA requires anchorages used for personal fall arrest systems to be capable of supporting 5,000 lbs per worker attached.
Question 6: Which component of a personal fall arrest system absorbs the energy of a fall by slowing the worker's descent?
- Anchorage connector
- Body harness
- Shock-absorbing lanyard or self-retracting lifeline (Correct answer)
- Horizontal lifeline
Correct answer: Shock-absorbing lanyard or self-retracting lifeline
Shock-absorbing lanyards and self-retracting lifelines are the energy-absorbing components that limit arrest forces on the worker.
Question 7: Under OSHA 1926.503, fall protection training must be provided by:
- Any experienced worker designated by the employer
- A competent person (Correct answer)
- A qualified person only
- A certified safety professional
Correct answer: A competent person
OSHA 1926.503 requires that fall protection training be conducted by a competent person with knowledge of fall hazards.
