,Q1. During the erection of a multi-story steel frame, a connector is working at a
height of 25 feet on a tied-arc building. Which statement accurately reflects OSHA's
fall protection requirements for this worker?
A. No fall protection is required because connectors are exempt from fall protection.
B. Fall protection is required unless the worker is within a controlled decking zone
(CDZ).
C. Fall protection may be waived if a safety monitor is used.
D. Fall protection is required because the height exceeds 15 feet, but the connector
exemption only applies up to 30 feet and requires the worker to be on a
walking/working surface that is flat and level.
Correct Answer: D. Fall protection is required because the height exceeds 15 feet, but
the connector exemption only applies up to 30 feet and requires the worker to be on a
walking/working surface that is flat and level.
Rationale: OSHA 1926.760(b)(3) provides a limited exemption for connectors working up
to 30 feet, but it is not absolute; they must be on a walking/working surface that is flat and
level, and fall protection is still required if the surface is not flat or if the height exceeds 30
feet. At 25 feet, the exemption may apply only if conditions are met, but the stem implies
the building is tied-arc (curved), likely not flat, so fall protection is required. Option D
correctly identifies the need for fall protection and the limits of the exemption.
Why Wrong:
A - Connectors are not categorically exempt; the exemption has specific conditions
including a maximum height of 30 feet and a flat walking surface.
B - Controlled decking zones (CDZ) are for decking work, not for connectors;
connectors rely on the connector exemption.
C - Safety monitors are not a substitute for fall protection in this context; they are used
only in specific low-slope roof scenarios.
Reference: OSHA 29 CFR 1926 Subpart R, §1926.760
Q2. A load hook on a crane used for structural steel erection is found to have its
throat opening permanently increased by 10% from the original dimension. What is
the required action regarding the hook's load capacity?
A. The hook may continue to be used at its original rated capacity.
B. The hook's capacity must be reduced to 75% of its original rating.
C. The hook's capacity must be reduced by 10%.
D. The hook must be immediately removed from service.
Correct Answer: B. The hook's capacity must be reduced to 75% of its original
rating.
Rationale: According to ASME B30.10 and OSHA standards, a load hook with a throat
opening increase exceeding 5% but less than 15% does not require immediate removal but
requires a reduction in capacity. The standard reduction is 25% (i.e., to 75% of original
Page 3
, capacity) for a 10% increase. Removal is required only if the increase is 15% or more.
Option B is correct.
Why Wrong:
A - A permanent deformation indicates potential fatigue; the hook cannot be used at
original capacity.
C - The reduction is not proportional; it is a fixed 25% reduction for a 10% increase.
D - Removal is required only if the throat opening increase is 15% or more.
Reference: ASME B30.10, Hooks, and OSHA 1926.1501
Q3. A lattice boom crawler crane is to lift a steel beam weighing 10 tons. The crane is
set up with outriggers fully extended. The load chart below is applicable. At a radius
of 50 feet, the capacity is 8.5 tons. What is the appropriate determination?
A. The lift is safe as long as the beam is lifted within the crane's chart.
B. The lift is unsafe because the load exceeds the capacity at that radius.
C. The lift is safe only if the beam is lifted with a tagline to reduce side load.
D. The lift is safe if the load is reduced by 10% due to wind conditions.
Correct Answer: B. The lift is unsafe because the load exceeds the capacity at that
radius.
Rationale: The load at radius 50 ft is 10 tons, but the crane's capacity is only 8.5 tons.
This exceeds the manufacturer's rated capacity, making the lift unsafe regardless of
auxiliary measures. The crane must be used within its load chart limits. Option B is
correct.
Why Wrong:
A - The load exceeds the capacity, so it is not within the chart's safe limits.
C - Taglines do not increase capacity; they only control load rotation.
D - Wind conditions would require a reduction in capacity, but the base lift already
exceeds capacity.

Q4. A slip-critical connection is being installed with ASTM A325 bolts using the
turn-of-nut method. The ironworker first snugs the bolts, then rotates the nut
one-half turn. What additional step is required to ensure proper tension?
A. No additional step; the installation is complete.
B. Calibration of a torque wrench must be performed on a representative sample.
C. The bolts must be inspected with an ultrasonic tension device.
D. A lock washer must be installed under the nut.
Correct Answer: A. No additional step; the installation is complete.
Rationale: For the turn-of-nut method, after snug-tightening, a specified rotation (e.g., 1/2
turn for A325 bolts) is sufficient to achieve required tension. No additional calibration or
