1. What is the primary responsibility of a qualified signalperson during crane
operations?
A. Determine the crane's rated capacity
B. Inspect and repair the crane
C. Provide clear, accurate communication to direct crane movement safely
D. Select the crane operator
Answer: C. Provide clear, accurate communication to direct crane movement
safely
Rationale: The signalperson's principal function is to communicate safely and
effectively with the operator when signaling is required. The signalperson does
not replace the operator's responsibility for safe crane operation.
,2. When should a signalperson be used during a crane operation?
A. Only when the load weighs more than 10,000 pounds
B. Only during nighttime operations
C. When the operator cannot safely see the load, landing area, or travel path, or
when required by the operation
D. Only when a supervisor requests one
Answer: C. When the operator cannot safely see the load, landing area, or travel
path, or when required by the operation
Rationale: A signalperson is particularly important when the operator's direct
view is obstructed or when communication conditions make direct observation
insufficient for safe operation.
3. What should a signalperson do if the operator does not appear to understand
a signal?
A. Repeat the signal faster
B. Continue signaling until the operator responds
C. Stop the operation and establish clear communication before proceeding
D. Shout a different instruction without stopping
Answer: C. Stop the operation and establish clear communication before
proceeding
Rationale: Ambiguous communication creates an immediate hazard. The
signalperson should ensure that the intended instruction is understood before
movement continues.
4. Which characteristic is most important when giving crane signals?
A. Complexity
B. Speed
,C. Clarity and consistency
D. Loudness
Answer: C. Clarity and consistency
Rationale: Signals must be readily understood by the operator. Consistent
standardized signals reduce the possibility of misinterpretation.
5. What is the purpose of a standardized crane hand-signal system?
A. To reduce operator responsibility
B. To eliminate the need for planning
C. To provide consistent visual instructions between signalperson and operator
D. To allow multiple people to signal simultaneously
Answer: C. To provide consistent visual instructions between signalperson and
operator
Rationale: Standardized signals establish a common language that reduces
communication errors during lifting operations.
6. What does the standard hand signal for "hoist" generally involve?
A. Thumb pointing downward
B. Forearm vertical with index finger pointing upward and making a circular
motion
C. Arm extended horizontally and waving
D. Both hands crossing overhead
Answer: B. Forearm vertical with index finger pointing upward and making a
circular motion
Rationale: The standard hoist signal uses an upward-pointing index finger with
a circular motion to direct the operator to raise the load.
, 7. What does the standard hand signal for "lower" generally involve?
A. Index finger pointing upward
B. Both arms extended sideways
C. Forearm vertical with index finger pointing downward and making a circular
motion
D. Palm facing the operator and held stationary
Answer: C. Forearm vertical with index finger pointing downward and making a
circular motion
Rationale: The downward-pointing index finger and circular motion is the
standard visual signal for lowering.
8. What is the correct response to a stop signal?
A. Continue until the next scheduled signal
B. Slow down but continue
C. Stop crane movement promptly and safely
D. Hoist the load
Answer: C. Stop crane movement promptly and safely
Rationale: A stop signal is intended to immediately interrupt crane movement. A
signalperson should never assume that a stop instruction is optional.
9. What should a signalperson do if an emergency condition develops?
A. Continue the planned signal sequence
B. Wait for the supervisor
C. Give the appropriate stop or emergency signal and communicate the hazard
D. Move closer to the load
