First, describe the work and worksite
A specialist pump operator and site crew will position a truck-mounted concrete boom pump on a released ground-level setup pad for a building slab pour. This analysis ends at setup handover before concrete delivery. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Ground support, outrigger arrangement and operating envelope must be established for the actual pump.
- The pad is separated from pedestrians and delivery routes, with identified buried structures and overhead electrical lines.
- Concrete placement, end-hose handling, line blockage, cleanout and road travel require separate analyses.
Questions before work
- Who verifies ground capacity and buried structures beneath each support?
- Which outrigger arrangement and boom envelope are permitted by this model?
- What electrical clearances and utility coordination apply to this location?
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. Release the setup pad
Hazard: A support can punch through weak ground or a hidden vault, overturning the pump.
Control: Site lead provides ground and underground-structure information; operator checks the required support area against pump loads and instructions. Obtain competent technical review where capacity is unresolved; do not guess from surface appearance.
Verification: Site lead and operator record the support basis before the truck enters.
Why this belongs in the analysis: Visible level ground does not establish bearing capacity.
2. Separate truck movement
Hazard: Backing or positioning can strike a worker or trap a guide.
Control: Establish an exclusive positioning zone and agreed operator-guide signals. Guides stay visible and outside wheel and crush paths; stop if communication is lost.
Verification: Movement lead checks pedestrian and ready-mix routes before positioning.
Why this belongs in the analysis: The setup movement must remain separate from pour traffic.
3. Deploy supports
Hazard: Outrigger movement can crush hands; an unsuitable pad or partial extension can destabilize the unit.
Control: Operator deploys the model-specific outrigger configuration on selected supports. Keep workers out of moving support paths. Partial extension is allowed only when the actual system explicitly permits and controls it.
Verification: Operator compares deployed supports and level with the model instructions.
Why this belongs in the analysis: A familiar truck silhouette does not prove the configuration is permitted.
4. Establish the boom envelope
Hazard: The boom can contact energized lines, structures or occupied work.
Control: Identify line voltage and the applicable clearance method with the responsible parties. Operator defines a restricted boom envelope and designated observation where needed; do not transfer a crane clearance rule to a pump without checking applicability.
Verification: Lead documents the electrical boundary and checks the full proposed boom movement.
Why this belongs in the analysis: Pump-specific electrical planning must precede unfolding.
5. Inspect and function check
Hazard: Defective controls, hydraulics or pipeline restraints can allow unintended movement or separation.
Control: Qualified operator completes the pump inspection and safe function checks under its manual. Check emergency controls and the planned supported delivery-line connections; take defective equipment out of service.
Verification: Operator records defects and confirms the test area remains clear.
Why this belongs in the analysis: A completed support setup does not verify the pumping system.
6. Hand over for the pour
Hazard: An arriving truck or placing crew can enter an uncoordinated pump zone.
Control: Brief delivery and placing leads on exclusion zones, communication, boom restrictions and setup monitoring. Require the separate placement and hose analysis before concrete starts.
Verification: Receiving leads confirm responsibilities and stop signals at handover.
Why this belongs in the analysis: This setup analysis intentionally ends before concrete discharge.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Operator deploys the model-specific outrigger configuration on selected supports. Keep workers out of moving support paths. Partial extension is allowed only when the actual system explicitly permits and controls it. |
| Check that everything is ready. | Site lead provides ground and underground-structure information; operator checks the required support area against pump loads and instructions. Obtain competent technical review where capacity is unresolved; do not guess from surface appearance. |
Decisions that change the analysis
Does the published slab pour cover pump setup?
Its concrete distribution scenario assumes a released pump arrangement. This example addresses ground support, outriggers and boom clearance before that handover; it does not repeat end-hose operation.
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
- Support settlement, ground cracking or loss of level.
- Electrical boundary, boom envelope or delivery route changes.
- A defect, unauthorized support configuration or communication failure.
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
- Actual pump model operation, support deployment and emergency controls for the assigned operator.
- Site team instruction on ground-support evidence, electrical boundaries and truck communication.
Confirm applicable qualifications, task instruction and actual training evidence for the people assigned. Related toolbox talks support crew discussion; 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.
