1. Which of the following is the primary responsibility of a signalperson?
a) Inspecting cranes
b) Operating the crane
c) Communicating safe crane movements
d) Calculating load weight
Rationale: The signalperson’s main role is to communicate with the
crane operator to ensure safe movement of loads.
2. Before starting a lift, a signalperson should:
a) Inspect the crane's mechanical components
b) Ensure the path of the lift is clear and safe
c) Operate the hoist slowly
d) Measure the load's width
, Rationale: The signalperson must verify that the area around the lift
is clear and safe for operation.
3. The standard hand signal to stop a crane is:
a) One arm raised and rotating
b) Both arms extended horizontally, palms down, then waving
c) Arm extended downward
d) Arm pointing up
Rationale: The stop signal involves both arms extended horizontally,
palms down, and moving side to side.
4. When using radio communication, the signalperson should:
a) Speak rapidly to save time
b) Use slang or abbreviations
c) Speak clearly, use standard terms, and confirm messages
d) Only speak when the crane is moving
Rationale: Clear, standard communication ensures the operator fully
understands instructions.
5. What should a signalperson do if they cannot see the load?
a) Guess the operator’s actions
b) Continue signaling as usual
c) Stop the lift and get a clear line of sight or another signalperson
d) Use hand signals anyway
Rationale: The signalperson must always maintain visual contact
with the load or use an assistant; guessing is unsafe.
,6. When signaling a load to be lowered, the hand signal is:
a) Arm raised and waving side to side
b) One arm pointing forward, then moving up and down
c) Arm pointing downward, moving up and down
d) Both arms rotating
Rationale: Lowering the load requires the arm pointing down and
moving up and down.
7. Which of the following is true regarding blind lifts?
a) They can be done without planning
b) Only trained signalpersons using radios or prearranged signals
should conduct blind lifts
c) Anyone can perform them
d) Visual contact is not required
Rationale: Blind lifts are high-risk and require trained personnel and
reliable communication methods.
8. When signaling a crane to travel, the signalperson should:
a) Stand behind the crane
b) Signal randomly
c) Signal from a location where the operator can clearly see the
signal
d) Only use voice commands
Rationale: The signalperson must be positioned to maintain clear
communication with the operator.
, 9. A "hoist" command means:
a) Lower the load
b) Swing the crane
c) Raise the load
d) Stop the crane
Rationale: "Hoist" indicates that the crane operator should raise the
load vertically.
10. The most important factor in preventing crane accidents is:
a) Load weight
b) Crane type
c) Clear and correct communication
d) Operator skill alone
Rationale: Even skilled operators rely on accurate communication
from signalpersons to prevent accidents.
11. Which type of personal protective equipment (PPE) is required
for a signalperson?
a) Earplugs only
b) Steel-toed boots only
c) Hard hat, high-visibility vest, and safety boots
d) Gloves only
Rationale: Signalpersons must wear PPE that ensures visibility and
protection on the job site.
