according to OSHA 1926.1408?
A. 10 feet
B. 15 feet
,2
C. 20 feet
D. 25 feet
Correct Answer: B. [CORRECT]
Rationale: OSHA 1926.1408 Table A establishes minimum clearance of 15 feet for power lines
rated over 50 kV but not exceeding 200 kV, with additional 0.4 inches required for each 1 kV
over 50 kV.
Q4: According to OSHA 1926.1412, how frequently must a documented periodic inspection be
performed on mobile cranes in active service?
A. Daily
B. Weekly
C. Monthly

covering safety and operational theory and practical hands-on training demonstrating
competency in equipment operation.
Q7: According to OSHA 1926.1404, when must a signal person be provided during crane
operations?
A. Only when lifting over 10,000 lbs

OSHA 1926.1407?
A. Immediately move the crane away from the line
B. Remain inside the cab and warn others to stay away
C. Jump clear and run away
D. Attempt to break contact using a non-conductive pole
Correct Answer: B. [CORRECT]
Rationale: OSHA 1926.1407 requires operators to remain inside the crane cab if contact occurs,
as the cab provides equipotential protection, and warn all personnel to stay at least 35 feet away
until utility company de-energizes the line.

A. High school diploma
B. Certification by an accredited crane operator testing organization
C. 5 years of experience
D. Employer authorization only
Correct Answer: B. [CORRECT]
Rationale: ASME B30.5 requires crane operators to be certified by an accredited testing
, 4
organization (NCCCO, NCCER, or equivalent) or qualified through employer auditable
assessment program meeting OSHA 1926.1427 requirements.
Q10: According to OSHA 1926.1402, what is the minimum distance that must be maintained
from the edge of an excavation when setting up a crane?
A. 3 feet
B. 5 feet
C. 10 feet or twice the excavation depth, whichever is greater
D. 20 feet regardless of depth
Correct Answer: C. [CORRECT]
Rationale: OSHA 1926.1402(b) requires equipment to be kept at least 10 feet or twice the
excavation depth (whichever is greater) from the edge to prevent ground collapse and crane
tipping hazards.
Q11: What does the hand signal "both fists in front of body, thumbs pointing outward" indicate?
A. Hoist
B. Lower
C. Extend boom
D. Retract boom
Correct Answer: C. [CORRECT]
Rationale: The standard hand signal for extend boom is both fists in front of body with thumbs
pointing outward, indicating telescoping boom extension per OSHA 1926.1404 Appendix A.
Q12: Under ASME B30.31, what is the maximum allowable operating radius for digger derricks
when not performing lifting operations?
A. 15 feet
B. Manufacturer's specified limit
C. 25 feet
D. Unlimited if not lifting
Correct Answer: B. [CORRECT]
Rationale: ASME B30.31 requires digger derrick operations to remain within manufacturer-
specified operating radii for all operations, including digging and pole setting, to maintain
structural integrity and stability.
