Sample WSQ SSLO (Lifting Supervisor) Practice Questions

Try these sample questions to test your WSQ SSLO (Lifting Supervisor) 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, when must a lifting plan be established for a crane lifting operation?
A.Only for tandem lifts or night work
B.After the first lift of the day has been completed safely
C.Before any lifting operation involving the use of a crane is carried out
D.Only when the load exceeds 5 tonnes
Explanation: Regulation 4 of the WSH (Operation of Cranes) Regulations requires a lifting plan to be established before any crane lifting operation. The plan guides coordination, briefing and safe execution for every crane lift, not only heavy or unusual lifts.
2A lifting supervisor is briefing the crane operator, rigger and signalman. Which document must the briefing cover according to the lifting supervisor's statutory duties?
A.The company's annual safety audit report
B.The manufacturer's crane sales brochure
C.The lifting plan for the operation
D.The site traffic management plan only
Explanation: The WSH (Operation of Cranes) Regulations require the appointed lifting supervisor to brief all crane operators, riggers and signalmen on the lifting plan. That briefing aligns the whole lifting team to the planned method, loads, positions and controls.
3Which item is most appropriately included in a crane lifting plan for a construction site lift?
A.Load weight and centre of gravity, crane type and capacity, lifting points, sequence, and exclusion zones
B.The canteen menu for the lifting crew
C.Only the crane operator's home address
D.The colour of the crane's paint
Explanation: A workable lifting plan describes the load (weight and CG), crane selection and capacity, lifting points and gear, lift path/sequence, personnel roles, and measures such as exclusion zones. Those details let the supervisor verify SWL and control hazards before lifting.
4Who is responsible for coordinating all lifting activities and supervising mobile or tower crane operations in accordance with the lifting plan?
A.The appointed lifting supervisor
B.Any available general worker on site
C.The site security officer
D.The crane manufacturer's sales representative
Explanation: Under the Operation of Cranes Regulations, the appointed lifting supervisor must coordinate all lifting activities and supervise mobile or tower crane operations in accordance with the lifting plan. That role is a named appointment, not an ad-hoc task for unrelated personnel.
5A permit-to-work (PTW) is linked to a complex crane lift near live plant. How should the lifting supervisor treat the relationship between the PTW and the lifting plan?
A.Ignore the PTW once the lifting plan is signed
B.Cancel the lifting plan because a PTW alone is always sufficient
C.Allow the lift to start if either document exists, even if the other is incomplete
D.Treat the PTW and lifting plan as complementary controls and ensure both are followed before and during the lift
Explanation: For higher-risk work, organisational PTW systems and the statutory lifting plan work together. The supervisor must ensure adherence to legislation and organisational safe work procedures, which typically means both the PTW conditions and the lifting plan are in place and followed.
6During pre-lift planning, the intended load weight is uncertain because packing notes are missing. What should the lifting supervisor do?
A.Estimate by eye and proceed to keep the schedule
B.Use the crane's maximum rated capacity as the assumed load weight
C.Stop the lift until the load weight and centre of gravity are reliably established and checked against the crane's SWL
D.Ask the newest rigger to guess the weight
Explanation: Load weight and centre of gravity are fundamental lifting-plan inputs used to select gear and verify SWL on the load chart. Proceeding on guesswork risks overload, tipping or gear failure; the supervisor must obtain reliable load data before lifting.
7Why must the lifting plan identify the sequence of lifts and landing positions?
A.Because sequences are optional decorative text
B.Only to satisfy an insurance marketing brochure
C.So the team can coordinate crane movements, tagline control and exclusion zones without improvising mid-lift
D.To decorate the site notice board
Explanation: A clear lift sequence and landing positions let the supervisor, operator, rigger and signalman coordinate movements, keep people clear, and avoid mid-lift improvisation that creates struck-by and overload hazards.
8A revised lifting plan changes the crane position and working radius. What must the lifting supervisor do before the next lift?
A.Proceed without re-briefing because the crew already knows the old plan
B.Only update the plan file after the shift ends
C.Tell only the rigger and leave the operator uninformed
D.Re-brief the crane operator, rigger and signalman on the revised plan and re-check SWL for the new radius
Explanation: Plan changes that affect crane position or radius change capacity and exclusion needs. The supervisor must brief the whole lifting team on the revised plan and verify the intended lift remains within SWL at the new configuration.
9Which statement best describes the lifting supervisor's duty regarding who may participate in mobile or tower crane lifting operations?
A.Only registered crane operators, and appointed riggers and signalmen, may participate as required for those roles
B.Any licensed driver on site may operate the crane if the supervisor is busy
C.Visitors may act as signalmen if they watch a short video
D.The supervisor may operate the crane while also signalling
Explanation: The regulations require the lifting supervisor to ensure that only registered crane operators and appointed riggers and signalmen participate in mobile or tower crane lifting operations. Mixing unappointed or unregistered people into those roles is a compliance and safety failure.
10When planning a tandem lift with two cranes, what planning principle should the lifting supervisor apply?
A.Follow approved code-of-practice requirements for tandem lifting, including clear load sharing, communication and a detailed lifting plan
B.Treat tandem lifts as routine single-crane lifts with no extra controls
C.Allow each crane operator to invent their own method independently
D.Remove all taglines to speed up the dual lift
Explanation: Tandem lifts are higher risk because load sharing and synchronisation can overload one crane. SSLO underpinning knowledge requires tandem techniques and requirements based on approved codes of practice, reflected in a detailed plan and tight coordination.

About the WSQ SSLO (Lifting Supervisor) Exam

The WSQ Supervise Safe Lifting Operations competency unit (TSC Code GMS-COM-3306-1.1-E), formerly the Lifting Supervisor Safety Course, equips appointed lifting supervisors to prepare for, supervise, and reinstate safe lifting operations involving mobile, tower or other cranes. It covers three competency elements — prepare to supervise, carry out supervision, and supervise reinstatement — and underpinning knowledge spanning risk assessment, legislation and lifting plans, roles of lifting personnel, load charts and SWL, crane types and safety devices, slinging/rigging, exclusion zones, emergency response, and post-lift checks. Under the WSH (Operation of Cranes) Regulations, a competent lifting supervisor must be appointed before crane lifting operations.

WSQ SSLO (Lifting Supervisor) Study Tips from Top Performers

1Memorise what must appear in a lifting plan and practise briefing crane operators, riggers and signalmen on it — Section A weights lifting-plan questions heavily and any lift without a plan is a regulatory failure.
2Drill load-chart reading (radius, boom length/angle, capacity) until you can get every chart item right — Section B requires 100% and a single wrong answer fails the whole assessment.
3Revise the statutory duties of the lifting supervisor, registered crane operator, appointed rigger and signalman under the WSH (Operation of Cranes) Regulations, including who may operate mobile and tower cranes.
4Walk through CE 1–3 in order: prepare (RA, PPE, inspections, barricades), supervise (hazards, follow the plan, stop unsafe work), then reinstate (housekeeping, post-checks, defect reporting, ERP and investigation support).
