1. What is the primary responsibility of a qualified signalperson during a crane
operation?
A. Inspecting the crane's engine
B. Directing the movement of the load and communicating with the operator
C. Determining the crane's maximum rated capacity
D. Repairing defective rigging
Answer: Directing the movement of the load and communicating with the
operator
Rationale: A signalperson's primary function is to communicate safe movement
instructions to the crane operator when the operator cannot adequately see or
control the load path.
, 2. When should a signalperson give a STOP signal?
A. Only when the load reaches the destination
B. Only when the operator requests it
C. Whenever an unsafe condition develops or the operation must be halted
D. Only when the load exceeds 10,000 pounds
Answer: Whenever an unsafe condition develops or the operation must be
halted
Rationale: A stop command is safety-critical and must be given whenever
continuing the movement could create a hazard.
3. Who should normally give routine crane signals when only one signalperson
is designated?
A. Every worker on the site
B. The designated signalperson
C. The crane owner
D. The rigger's supervisor only
Answer: The designated signalperson
Rationale: Using one designated signalperson reduces conflicting instructions
and establishes clear communication with the operator.
4. If the crane operator loses sight of the signalperson during a blind lift, what
should happen?
A. The operator should continue slowly
B. The operator should follow the last signal indefinitely
C. The operation should be stopped until communication is restored
D. The operator should accelerate the lift
Answer: The operation should be stopped until communication is restored
Rationale: Continuing without reliable communication can cause uncontrolled
load movement and serious injury.
, 5. Which signal is generally used to indicate that the crane should hoist the
load?
A. Arm extended downward with palm down
B. Forearm vertical with finger pointing upward and hand moving in small circles
C. Both arms crossed
D. Arm extended horizontally with palm down
Answer: Forearm vertical with finger pointing upward and hand moving in small
circles
Rationale: This is the conventional crane hand signal for hoisting.
6. What is the principal danger of giving contradictory crane signals?
A. Increased fuel consumption
B. Operator confusion and unintended load movement
C. Excessive engine temperature
D. Reduced hook capacity
Answer: Operator confusion and unintended load movement
Rationale: Conflicting signals can cause the operator to make an incorrect
movement at the exact moment workers are exposed to the load.
7. A signalperson should position themselves primarily where they can:
A. Stand directly beneath the load
B. See the load and operator or maintain reliable communication with the
operator
C. Stand behind the crane counterweight
D. Touch the suspended load
Answer: See the load and operator or maintain reliable communication with the
operator
Rationale: The signalperson must have an effective view of the operation and a
dependable communication method.
, 8. What should a signalperson do if an unauthorized person begins giving
signals to the operator?
A. Ignore the situation
B. Continue giving signals faster
C. Stop the operation and establish one authorized signal source
D. Allow both people to signal simultaneously
Answer: Stop the operation and establish one authorized signal source
Rationale: Only a clearly established signalperson should provide routine signals
unless emergency conditions require an immediate stop.
9. What does the crane hand signal for lowering generally involve?
A. Forearm vertical with finger pointing upward
B. Arm extended downward with forearm moving in small circles
C. Both hands placed on the hips
D. Arm held horizontally with palm facing upward
Answer: Arm extended downward with forearm moving in small circles
Rationale: The conventional signal for lowering is performed with the arm
extended downward and the hand making small circular motions.
10.Why should crane signals be given distinctly rather than rapidly or casually?
A. The operator may misunderstand the intended movement
B. It increases crane capacity
C. It prevents hydraulic leaks
D. It reduces the load weight
Answer: The operator may misunderstand the intended movement
Rationale: Clear, deliberate signals reduce the possibility of miscommunication
during critical load movements.
