Total Questions: 80 | Passing Score: 70% | Time Allowed: 120 minutes
Instructions: Select the single best answer for each question. Correct answers
are highlighted in bold with a rationale.
Topic 1: Fall Prevention & Protection (Questions 1-15)
1. According to OSHA 1926.501, at what minimum height is fall protection
required for workers on a residential roof?
a) 6 feet
b) 10 feet
c) 6 feet (residential construction – 2026 reaffirmed)
d) 15 feet
Rationale: OSHA’s final rule for residential construction maintains 6 feet for fall
protection, aligning with general industry.
2. Which anchorage strength is required for a personal fall arrest system
(PFAS) under 1926.502(d)(15)?
a) 3,000 lbs per worker
b) 5,000 lbs per worker
c) 10,000 lbs per worker
d) 2x the maximum arresting force
Rationale: Anchorages must support 5,000 lbs per attached worker or be designed
by a qualified person with a 2:1 safety factor.
,3. (2026 Update) What is the new requirement for self-retracting lanyards
(SRLs) used on leading edges?
a) Must be leading-edge certified and have a reduced arrest distance
b) Can be any SRL with a 6-foot lanyard
c) Must be connected to a horizontal lifeline only
d) No change – SRLs banned on leading edges
*Rationale: ANSI/ASSP Z359.16-2024 (adopted by reference in 2026) requires
leading-edge-certified SRLs with max arrest distance ≤ 24 inches.*
4. Guardrail systems must withstand a force of at least ____ pounds applied in
any direction at any point along the top rail.
a) 100
b) 150
c) 200
d) 250
*Rationale: OSHA 1926.502(b)(5): top rails must resist 200 lbs of
downward/outward force.*
5. Safety nets must be drop-tested with a ____ pound bag from the highest
working level.
a) 200
b) 400
c) 500
d) 600
*Rationale: Per 1926.502(c)(4), a 400-lb sand bag (30” diameter) simulates a
falling worker.*
6. When using a body harness, the dorsal D-ring should be located:
a) Lower back
b) Sternum
c) Between the shoulder blades
d) Side hip
Rationale: Dorsal placement between shoulder blades ensures proper upright
orientation after a fall.
7. What is the maximum free-fall distance permitted for a PFAS unless using a
special rescue plan?
a) 2 ft
b) 6 ft
, c) 10 ft
d) 12 ft
Rationale: 1926.502(d)(16)(iii): maximum 6 ft free fall; longer requires engineered
system.
8. (2026) Which technology is now recommended by ANSI for monitoring fall
arrest harness wear?
a) RFID tags only
b) Smart textile sensors with IoT connectivity
c) Visual thread color change only
d) Ultrasonic thickness gauges
Rationale: 2026 guidelines embrace embedded conductive threads that report
webbing degradation via mobile app.
9. A positioning device system (e.g., for pole climbing) must limit free fall to:
a) 0 ft
b) 1 ft
c) 2 ft
d) 3 ft
Rationale: 1926.502(e)(2): positioning systems limit free fall to 2 ft and must hold
3,000 lbs.
10. What is the minimum breaking strength for a horizontal lifeline (single
worker)?
a) 3,000 lbs
b) 4,000 lbs
c) 5,000 lbs
d) 7,000 lbs
Rationale: Lifelines must have a safety factor of at least 2:1, but 5,000 lbs is the
design minimum per 1926.502(d)(11).
11. Which of the following is NOT an acceptable form of fall protection for
steel erection (1926.760)?
a) Warning lines + safety monitor
b) PFAS with 100% tie-off
c) Guardrails
d) Only controlled access zones
Rationale: Controlled access zones alone are not sufficient; steel erection requires
