1. A construction crew is working on a commercial building roof where
the leading edge is 18 feet above ground level. According to general
fall protection principles, which hazard presents the highest risk in this
scenario?
A. Electrical shock from nearby power lines
B. Falls due to unprotected leading edges
C. Heat stress from rooftop exposure
D. Noise-induced hearing loss from machinery
B. Falls due to unprotected leading edges
Falls from unprotected leading edges represent one of the most severe
hazards in elevated work environments because they involve direct
exposure to a significant height difference without a physical barrier or
personal fall arrest system in place, increasing the likelihood of serious
injury or fatality.
, 2. A worker is selecting a personal fall arrest system. Which combination
of components is required for a complete system?
A. Safety glasses, gloves, and helmet
B. Harness, lanyard, and anchor point
C. Ladder, scaffolding, and guardrails
D. Hard hat, boots, and reflective vest
B. Harness, lanyard, and anchor point
A complete personal fall arrest system requires a full-body harness to
distribute arrest forces, a lanyard or lifeline to connect the worker, and a
secure anchorage point capable of supporting required loads during a fall
event.
3. What is the maximum allowable free fall distance before a fall arrest
system must engage effectively under standard safety guidelines?
A. 2 feet
B. 4 feet
C. 6 feet
D. 10 feet
C. 6 feet
Safety standards typically limit free fall distance to 6 feet or less to reduce
impact forces on the body and system components, ensuring the arrest
system can safely decelerate the worker without causing severe injury.
4. When inspecting a full-body harness before use, which condition
would require immediate removal from service?
A. Slight fading of the manufacturer label
B. Minor surface dirt on webbing
,C. Frayed stitching or torn webbing
D. Stiff but intact leg straps
C. Frayed stitching or torn webbing
Frayed stitching or torn webbing indicates structural compromise of the
harness fibers, which significantly reduces load-bearing capacity and
makes the equipment unsafe for fall protection use.
5. Which of the following is the primary purpose of a shock-absorbing
lanyard?
A. To increase worker mobility
B. To reduce arresting force during a fall
C. To extend the working height range
D. To replace the need for anchor points
B. To reduce arresting force during a fall
Shock-absorbing lanyards are designed to dissipate energy generated
during a fall, thereby reducing the force transmitted to the worker’s body
and minimizing potential injury.
6. A worker is required to connect to an anchorage point. What is the
minimum strength requirement for a certified anchorage used in fall
protection?
A. 1,000 pounds per worker
B. 2,000 pounds per worker
C. 3,000 pounds per worker
D. 5,000 pounds per worker
D. 5,000 pounds per worker
, Anchorage points must typically support at least 5,000 pounds per
attached worker to ensure they can withstand the dynamic forces
generated during a fall arrest event without failure.
7. Which system prevents a worker from reaching a fall hazard zone
entirely?
A. Fall arrest system
B. Positioning system
C. Fall restraint system
D. Retrieval system
C. Fall restraint system
A fall restraint system is designed to physically restrict a worker’s
movement so they cannot reach a leading edge or fall hazard zone,
eliminating the possibility of a fall before it occurs.
8. What is the correct action if a lanyard has been involved in a fall arrest
event?
A. Reuse after inspection
B. Repair and reuse immediately
C. Remove from service permanently
D. Wash and store for future use
C. Remove from service permanently
Any lanyard involved in a fall arrest is subjected to forces beyond safe
reuse thresholds, and structural integrity may be compromised even if
damage is not visible, requiring permanent removal.
9. Which factor most directly increases fall distance in a personal fall
arrest system?
