Question 4
What OSHA subpart specifically governs cranes and derricks in
construction?
A. Subpart C (General Safety)
B. Subpart CC (Cranes and Derricks in Construction)
C. Subpart K (Electrical)
D. Subpart N (Helicopters)

A. Continue operating until the end of the shift
B. Attempt to weld or fix the defect themselves
C. Take the equipment out of service immediately and tag
it out before any operation begins
D. Report it at the weekly safety meeting
Correct Answer: C
Rationale: OSHA prohibits operating any crane with an
uncorrected safety deficiency; equipment must be immediately
tagged out of service.
Question 6
According to OSHA 1926.1417, when an operator leaves the

B. Leave the engine running to keep the batteries charged.
C. Hang the pendant control over the hook.
, D. Leave the load suspended mid-air with the brakes
locked.
Correct Answer: A

hazards; OSHA requires positive securing measures including
landing loads and de-energizing controls.
Question 7
When must a designated signal person be used during crane
operations under OSHA guidelines?
A. Only during night shifts
B. Whenever the operator's view is obstructed, when
operating in tight areas, or when directed by site safety
rules
C. Signal persons are optional at all times
D. Only for lifts exceeding 100 tons
Correct Answer: B
Rationale: OSHA requires qualified signal persons whenever
line-of-sight is blocked, blind spots exist, or complex
