CHST CHST - Construction Health and Safety Technician Fall Protection and Prevention Questions and Answers 4 — Questions and Answers
Question 1: A warning line system on a low-slope roof must be erected at least how far from the roof edge for workers performing roofing work?
- 4 feet
- 6 feet (Correct answer)
- 10 feet
- 15 feet
Correct answer: 6 feet
OSHA 1926.502(f) requires warning lines to be set back at least 6 feet from the roof edge when used for roofing work.
Question 2: When using a positioning device system, the maximum free-fall must be limited to how many feet?
- 2 feet (Correct answer)
- 4 feet
- 6 feet
- 18 inches
Correct answer: 2 feet
Positioning device systems must be rigged to prevent a free fall of more than 2 feet per OSHA 1926.502(e).
Question 3: Which factor does NOT affect the total fall clearance distance calculation for a worker using a PFAS with a 6-foot lanyard?
- Deceleration distance
- Worker's height
- Harness stretch
- Manufacturer's rated capacity (Correct answer)
Correct answer: Manufacturer's rated capacity
Clearance distance accounts for lanyard length, deceleration distance, harness stretch, and worker height — not the harness's weight rating.
Question 4: Under OSHA standards, a competent person must inspect fall protection equipment at what minimum frequency?
- Monthly
- Before each use (Correct answer)
- Weekly
- Annually
Correct answer: Before each use
OSHA requires that fall protection equipment be inspected by a competent person before each use.
Question 5: What is the primary purpose of a self-retracting lifeline (SRL) compared to a standard shock-absorbing lanyard?
- It is rated for higher loads
- It automatically limits free-fall distance by locking during rapid descent (Correct answer)
- It eliminates the need for a full-body harness
- It allows longer working reach
Correct answer: It automatically limits free-fall distance by locking during rapid descent
An SRL locks almost immediately during rapid descent, greatly reducing free-fall distance compared to a fixed-length lanyard.
Question 6: When is a safety monitoring system (SMS) an acceptable sole means of fall protection on a low-slope roof?
- Any time a competent person is available
- Only for roofs 50 feet wide or less with a slope of 4:12 or less (Correct answer)
- Whenever fewer than 10 workers are on the roof
- Only on roofs with no penetrations
Correct answer: Only for roofs 50 feet wide or less with a slope of 4:12 or less
OSHA permits SMS as the sole fall protection method only on low-slope roofs 50 feet or less in width.
Question 7: Which type of anchorage is required when two workers use the same anchor point for a personal fall arrest system?
- 5,000-lb rated anchor
- Two separate 5,000-lb anchors
- A 10,000-lb rated anchor (Correct answer)
- A certified structural engineer must approve any shared anchor
Correct answer: A 10,000-lb rated anchor
When two workers share a single anchorage, the anchor must be rated to at least 10,000 pounds to accommodate both.
