Try these sample questions to test your WSQ Rigger & Signalman (PRST) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under the Workplace Safety and Health (Operation of Cranes) Regulations, who must appoint a rigger before a mobile or tower crane lifting operation?
A.The responsible person
B.Any nearby worker on site
C.The crane manufacturer
D.The client’s accounts department
Explanation: The WSH (Operation of Cranes) Regulations require the responsible person to appoint a trained rigger before lifting with a mobile or tower crane. Appointment is a legal duty, not an informal site custom.
2A person may act as a rigger for mobile or tower crane lifts in Singapore only if they have:
A.Watched a short site video once
B.Successfully completed a training course acceptable to the Commissioner
C.Been employed on site for one week
D.Owned a reflective vest
Explanation: The Regulations require that no one is appointed as a rigger unless they have successfully completed a training course acceptable to the Commissioner. Completing WSQ Perform Rigger and Signalman Tasks meets this expectation.
3The responsible person must ensure a rigger is attired so that the rigger is:
A.Hidden from the crane operator’s view
B.Dressed identically to all trades
C.Distinctively identified as a rigger
D.Wearing only casual sportswear
Explanation: WSH (Operation of Cranes) Regulations require the responsible person to ensure the appointed rigger is attired so as to be distinctively identified. Clear identification helps the lifting team and others on site.
4Which duty is specifically assigned to an appointed rigger under the Operation of Cranes Regulations?
A.Operate the crane from the cab
B.Appoint the lifting supervisor for the workplace
C.Approve the crane’s design registration as a PE
D.Ascertain the weight of the load and inform the crane operator
Explanation: Among the rigger’s statutory duties under the Operation of Cranes Regulations is ascertaining load weight and informing the crane operator. Accurate weight communication keeps the lift within crane and gear capacity.
5Before giving a clear lift signal, an appointed signalman must:
A.Ensure or verify with the rigger that the load is properly rigged
B.Leave the site so the operator works alone
C.Remove all tag lines permanently
D.Increase the sling angle beyond safe limits
Explanation: The signalman’s duties include verifying with the rigger that the load is properly rigged before signalling the lift, then giving correct clear signals to guide the load safely.
6Who may give signals to the crane operator during a mobile or tower crane lift?
A.Any passer-by who waves
B.Only an appointed signalman
C.Any untrained helper nearby
D.The delivery truck driver only
Explanation: The Regulations state that no person shall give signals to the crane operator unless they are an appointed signalman. Multiple unofficial signalers create confusion and serious accident risk.
7As part of preparing for rigger and signalman tasks, trainees must participate in:
A.A marketing presentation only
B.Payroll processing for the contractor
C.Risk assessment and lifting plan briefing for the lifting operation
D.Unrelated office filing work
Explanation: CE1 requires participating in risk assessment and lifting-plan briefing so the rigger understands hazards, control measures, and the planned sequence before work starts.
8A lifting plan for crane operations typically documents how the lift will be carried out safely. The rigger’s role in relation to the plan is to:
A.Ignore the plan if the weather is fine
B.Rewrite legislation during the lift
C.Delete defect reports after the brief
D.Understand and follow the briefed plan and related safe work procedures
Explanation: Riggers and signalmen must understand the lifting plan and safe work procedures briefed by the lifting supervisor so their actions align with planned controls and communication.
9Permit-to-work systems on lifting sites are used primarily to:
A.Authorise and control hazardous work under defined conditions and precautions
B.Replace the need for any PPE
C.Allow untrained people to operate cranes
D.Eliminate all communication requirements
Explanation: A permit-to-work helps authorise high-risk activities, confirm precautions, and control when work may proceed. It supports—not replaces—training, PPE, and clear communication.
10Under the Operation of Cranes Regulations, defects found in lifting gear should be reported by the rigger to the:
A.Site canteen vendor
B.Lifting supervisor
C.Crane manufacturer’s sales desk
D.Any passer-by outside the exclusion zone
Explanation: The rigger’s duties include reporting defects in lifting gear to the lifting supervisor so defective equipment is withdrawn and the lift is not continued unsafely.

WSQ Rigger & Signalman (PRST) Study Tips from Top Performers

1Memorise the rigger’s and signalman’s statutory duties from the Operation of Cranes Regulations—especially weight communication, sling checks/angles, padding, loose-load receptacles, defect reporting, and verifying the load before signalling.
2Drill the WSHC handbook hand signals (hoist, lower, slew, jib up/down, travel, telescoping, stop, emergency stop) until you can give and recognise them without hesitation.
3Practise the 3-step lift: take up slack, lift slightly and check balance/security, then continue only if stable—and never stand under a suspended load or leave unused sling legs dangling.
