CATEGORY 1: SAFETY REGULATIONS AND STANDARDS (Questions 1-25)
QUESTION 1:
What is the primary OSHA regulation governing cranes and derricks in construction?
a) 29 CFR 1926.1400
b) 29 CFR 1910.179
c) ASME B30.5
d) ANSI/ASME B30.9
CORRECT ANSWER: a) 29 CFR 1926.1400
RATIONALE: OSHA's Cranes and Derricks in Construction standard is found in 29 CFR
Part 1926, Subpart CC, with 1926.1400 being the core section that outlines the scope
and application of the rule. This regulation became effective in 2010 and applies to most
construction cranes.
QUESTION 2:
Which standard provides detailed safety provisions for the construction, installation,
operation, inspection, and maintenance of mobile cranes?
a) OSHA 1910.179
b) ASME B30.5
c) ANSI/ASSE A10.5
d) API RP 2D
CORRECT ANSWER: b) ASME B30.5
RATIONALE: ASME B30.5 is the "Mobile and Locomotive Cranes" safety standard, and it
serves as the primary technical reference for crane operation and safety practices
1
,alongside OSHA regulations. It covers design, construction, installation, operation,
inspection, testing, maintenance, and repair.
QUESTION 3:
According to OSHA, which accessible area of an operating crane must always be
barricaded?
a) The area directly under the load
b) The entire swing radius of the crane
c) The operator's cab area
d) The area within 10 feet of the outriggers
CORRECT ANSWER: b) The entire swing radius of the crane
RATIONALE: OSHA requires that the swing radius of the crane be barricaded to prevent
personnel from being struck by the rotating superstructure or counterweight. This area
must be clearly marked and restricted during crane operations.
QUESTION 4:
What is the minimum approach distance for a crane operating near power lines up to 50
kV?
a) 5 feet
b) 10 feet
c) 15 feet
d) 20 feet
CORRECT ANSWER: b) 10 feet
RATIONALE: OSHA 1926.1408 requires a minimum clearance of 10 feet for power lines
up to 50 kV. For lines above 50 kV, the clearance increases by 4 inches for every 10 kV
over 50 kV.
QUESTION 5:
2
,Under OSHA regulations, who is responsible for conducting a pre-shift inspection of the
crane?
a) The site supervisor
b) The crane operator
c) The rigger
d) The safety manager
CORRECT ANSWER: b) The crane operator
RATIONALE: OSHA 1926.1413 requires that the crane operator conduct a pre-shift
inspection before operating the crane each day. The operator must check all critical
components and document any deficiencies found during the inspection.
QUESTION 6:
What does ASME B30.5 primarily address?
a) Overhead and gantry cranes
b) Mobile and locomotive cranes
c) Rigging hardware
d) Tower cranes
CORRECT ANSWER: b) Mobile and locomotive cranes
RATIONALE: ASME B30.5 is specifically titled "Mobile and Locomotive Cranes" and
covers safety requirements for these types of cranes, including telescopic boom cranes,
lattice boom cranes, and locomotive cranes.
QUESTION 7:
How often must a crane undergo a comprehensive annual inspection according to
OSHA?
a) Monthly
b) Quarterly
c) Annually
d) Every two years
3
, CORRECT ANSWER: c) Annually
RATIONALE: OSHA 1926.1412 requires that cranes undergo a comprehensive inspection
at least once every 12 months. This inspection must be performed by a qualified person
and includes a complete examination of all critical components and systems.
QUESTION 8:
What is the maximum allowable wind speed for crane operations under normal
conditions?
a) 15 mph
b) 25 mph
c) 30 mph
d) Depends on crane manufacturer's specifications
CORRECT ANSWER: d) Depends on crane manufacturer's specifications
RATIONALE: While many industry guidelines suggest 25-30 mph as a general limit, OSHA
requires that crane operations follow the manufacturer's wind speed limitations for the
specific crane configuration being used. The operator must consult the load chart for
wind restrictions.
QUESTION 9:
According to OSHA, what must be done if a crane is found to have a damaged or missing
guard?
a) Continue operation with caution
b) Immediately shut down the crane and repair before use
c) Notify the supervisor at the end of the shift
d) Use duct tape as a temporary fix
CORRECT ANSWER: b) Immediately shut down the crane and repair before use
