Question 1
According to ASME B30.3, an overhead power line is ALWAYS considered to be:
A. De-energized if there is no power on the jobsite
B. Safe as long as the load, hoist rope, and structure are kept at least 10 feet away
C. Energized until the power company has verified it is not energized
D. De-energized if the lines have a safety cover over them
Answer: C
Rationale: ASME B30.3 requires all overhead power lines to be treated as
energized until the utility company confirms de-energization. Safety covers (D) do
not guarantee de-energization, and maintaining distance (B) does not change the
line's status. The absence of power on the jobsite (A) is irrelevant because the line
may still be fed from another source.
Question 2
According to ASME B30.3, when shall pre-operational testing be performed?
A. After erection operations only
B. After erection and after each climbing operation
C. Only after modifications or repairs have been made
D. After initial climbing operations only
Answer: B
Rationale: Pre-operational tests are required after erection and after each climbing
operation to verify the crane is functioning correctly following these critical
structural changes. Testing only after erection (A) or only after climbing (D) is
incomplete. Modifications and repairs (C) also require testing, but that is not the
only time.

,Question 3
Which of the following OSHA regulations govern suspended personnel platforms?
A. OSHA 1934.235
B. OSHA 1926.1431
C. OSHA 1910.180
D. OSHA 1926.106
Answer: B
Rationale: OSHA 1926.1431 specifically covers cranes and derricks used to hoist
personnel, including suspended personnel platforms. OSHA 1910.180 (C) covers
general industry cranes, and the other citations are not applicable to construction
personnel hoisting.
Question 4
High-tensile bolts shall be marked with the manufacturer's designation and:
A. Strength rating
B. Tensile grade
C. Torque requirements
D. Bolt size
Answer: A
Rationale: High-strength structural bolts must be marked with the manufacturer's
symbol and a strength rating (e.g., A325, A490). Torque requirements (C) are
determined by the bolt type and size but are not marked on the bolt itself. Tensile
grade (B) and bolt size (D) are not the required markings.
Question 5
FAA standard 7460-1 requirement must be met for any obstruction more than:
A. 50 ft
B. 200 ft
C. 100 ft
D. 250 ft
Answer: B
pg. 2
,Rationale: FAA Form 7460-1 must be filed for any obstruction exceeding 200 feet
above ground level. The other heights listed do not trigger the FAA notification
requirement.
Question 6
According to OSHA Subpart CC, a personnel platform shall be proof tested with
what percentage of the platform's rated capacity?
A. 125%
B. 150%
C. 100%
D. 200%
Answer: A
Rationale: OSHA requires personnel platforms to be proof tested to 125% of their
rated capacity. A 150% test (B) is used for custom rigging hardware, not personnel
platforms. Testing at 100% (C) would not verify the safety margin.
Question 7
The drum flange shall extend a minimum of ______ above the top layer of rope
during operation.
A. One-half rope diameter but not less than 1 inch
B. One-half rope diameter but not less than 3/4 inch
C. One-half rope diameter but not less than 1/2 inch
D. One-half rope diameter but not less than 1/4 inch
Answer: A
Rationale: ASME B30.3 requires the drum flange to extend at least one-half rope
diameter above the top layer of rope, with a minimum of 1 inch. The smaller
minimums in options B, C, and D do not meet the code requirement.
Question 8
Installing counterweight/ballast, unfolding, telescoping the mast, and
reconfiguration of the crane shall be performed by a ______ person.
A. Certified
pg. 3
, B. Qualified
C. Designated
D. Competent
Answer: B
Rationale: These critical structural operations must be performed by or under the
supervision of a qualified person. A certified person (A) has a credential but the
code specifies "qualified." A competent person (D) is capable of identifying
hazards but may not have the engineering knowledge required for these tasks.
Question 9
According to ASME B30.3, maintenance personnel are permitted to operate a
crane only when:
A. It is a light load
B. Performing their duties
C. The operator is not available
D. Winds are less than 20 mph
Answer: B
Rationale: ASME B30.3 allows maintenance personnel to operate the crane only
while performing their assigned maintenance duties. Operating because the
operator is unavailable (C) or because the load is light (A) is not permitted under
the standard.
Question 10
According to OSHA, after the crane has been checked out and before personnel lift
operations begin, the crew should:
A. Check the oil in the engine
B. Have a pre-lift meeting
C. Inspect the cab for debris
D. Have lunch
Answer: B
Rationale: OSHA 1926.1431 requires a pre-lift meeting before personnel hoisting
operations begin. This meeting ensures all crew members understand the lift plan,
