First, describe the work and worksite
A trained roofing crew sets up and uses a purpose-built track-and-platform material hoist between a controlled ground station and a protected roof receiver. The actual model manual governs setup, support, controls and loading; no people ride the platform. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Partial roof-supply and access coverage: one material-only platform hoist; no improvised ladder winch, crane lift or personnel hoist.
- Ground bearing, track support and ties, power arrangement and protected receiving positions are accepted for the actual model.
- Workers use separate access and independent accepted fall-protection arrangements; the hoist is not a lifeline anchor.
Questions before work
- Who accepts model-specific supports, ties and the roof receiving arrangement before the first test?
- What keeps people out of the travel path and separates roof receiving from an unprotected edge?
- How do operator and receiver stop travel and verify the platform is stationary before unloading?
Build the analysis one step at a time
What will the worker do? How could someone be harmed? What prevents or reduces that exposure? Who checks the control, and when?
1. Accept the hoist layout and model instructions
Hazard: Wrong supports or a conflicting overhead route can cause collapse or electrical contact.
Control: Identify the actual model and current instructions. Accept the ground and roof conditions, track layout, ties, power and travel exclusion; resolve overhead obstructions and the separate protected receiver position.
Verification: Lead records layout acceptance and assigns trained operator and receiver roles.
Why this belongs in the analysis: A platform capacity label does not establish whether its installed support arrangement is safe.
2. Assemble the hoist with travel isolated
Hazard: Track sections or drive components can fall or trap hands during unsupported assembly.
Control: Assemble with power isolated using the actual-model sequence and designed supports. Control component handling and pinch points; install required ties and verify the track is secure before connecting the operating power.
Verification: Responsible installer checks assembly and support against the model instructions before startup permission.
Why this belongs in the analysis: Improvised bracing can change track forces and bypass the manufacturer’s intended support.
3. Inspect and perform the prescribed unloaded test
Hazard: A damaged cable, ineffective brake or failed control can release a load once material is added.
Control: Carry out the model’s pre-use inspections and unloaded operating checks with the travel zone clear. Test the prescribed stop and holding functions; take defective equipment out of service rather than continuing with a smaller load.
Verification: Operator records inspection and test results before accepting the first loaded cycle.
Why this belongs in the analysis: An unloaded test separates equipment-function checks from the additional hazard of moving material.
4. Load and secure a permitted material load
Hazard: Overweight or poorly secured material can slide, fall or destabilize the platform.
Control: Identify actual load weight and form, stay within the installed model’s limits and secure the material as specified. Keep hands clear and confirm the receiver is ready before travel; prohibit riding or climbing the track.
Verification: Operator checks the load, securement and clear travel path for each cycle.
Why this belongs in the analysis: A load below nominal weight can still be unsuitable because of its size, balance or retention.
5. Raise and receive through agreed signals
Hazard: Unexpected motion or an edge reach can crush a worker or cause a fall while unloading.
Control: Keep the travel exclusion active and use agreed signals. Receive from the accepted protected position; wait for the platform to stop and hold as specified before touching or removing material.
Verification: Receiver confirms stopped, stable arrival and communicates completion before the return movement.
Why this belongs in the analysis: The material platform and roof fall-protection system have different functions and acceptance criteria.
6. Stop, isolate and hand over the equipment
Hazard: An unattended control or unsupported dismantling can restart movement or release equipment.
Control: Park and shut down under the actual-model procedure, isolate against unauthorized use and clear loose materials. Inspect changed conditions before reuse; perform dismantling only through the separately planned support sequence.
Verification: Operator records shutdown and identifies defects or support changes that block another shift’s use.
Why this belongs in the analysis: Daily acceptance cannot be carried forward after the equipment or roof conditions change.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Carry out the model’s pre-use inspections and unloaded operating checks with the travel zone clear. Test the prescribed stop and holding functions; take defective equipment out of service rather than continuing with a smaller load. |
| Check that everything is ready. | Identify the actual model and current instructions. Accept the ground and roof conditions, track layout, ties, power and travel exclusion; resolve overhead obstructions and the separate protected receiver position. |
Decisions that change the analysis
Can workers use the hoist structure as a fall-arrest anchor?
No. This example uses separate accepted access and fall-protection arrangements. The material hoist carries the permitted material load and is not credited as a lifeline anchor or personnel access system.
What must the crew record for actual use?
Identify the actual equipment and work boundaries, responsible people, applicable criteria, inspection findings and open actions. Resolve changes with affected crews and obtain required project authorization before work.
Agree when the crew will pause
- Stop for support movement, damaged cable, failed brake or controls, lost signals, loose load or entry into the travel zone.
- Obtain a new plan for personnel transport, changed track layout, relocation or maintenance.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting. Keep unresolved actions visible.

1. Describe your work and site
2. Work through each task
Describe an observable step, how someone could be harmed, and the control that acts on that hazard. Identify who checks it and what evidence is needed.
3. Record changes, checks, and open actions
Walk the work area, review with the crew, and resolve missing controls. Follow the required approval process. This tool does not judge completeness, verify signatures or authorize work.

Training needs to confirm
- Train the operator and receiver on the actual platform hoist, setup acceptance, inspection, load limits and stop signals.
- Verify protected roof receiving and independent fall-protection competence; rehearse an interrupted cycle.
Confirm applicable qualifications, task instruction and actual training evidence for the people assigned. Related toolbox talks support toolbox talks; they do not establish competence.
Common questions
Can this example be used as a JSA?
Adapt its Task | Hazard | Control analysis to the employer’s format and actual conditions. The example is a teaching aid, not evidence that controls were checked.
What changes if the project requires an AHA?
Use the governing AHA format, risk method, supporting records and acceptance process. The published formwork AHA demonstrates that additional structure; changing a JHA title does not supply it.
