First, describe the work and worksite
A building concrete crew will place fresh concrete into a released ground-level footing form using a crane-suspended discharge bucket. Workers control discharge from designated positions beside the form. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Crane, rigging, bucket weight and receiving-form capacity are addressed in the lift and placement plans.
- The area has separated loading and discharge positions with protected reinforcing projections and safe footing access.
- This excludes pump hoses, elevated placement, riding the bucket and entry beneath a raised bucket.
Questions before work
- How are filled weight, bucket suspension and load route established?
- What controls prevent unintended gate opening?
- Where can the gate operator stand clear of the suspended bucket?
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 receiving footing
Hazard: An unsupported form or unsafe footing edge can fail as concrete is deposited.
Control: Foreperson confirms form and reinforcement release, safe access and protected projections. Match the placement sequence to receiving capacity and keep unrelated workers outside the discharge zone.
Verification: Foreperson compares the planned sequence with the current form release.
Why this belongs in the analysis: The crane plan does not release the form for loading.
2. Inspect and fill the bucket
Hazard: A defective gate or overload can spill concrete or exceed lifting capacity.
Control: Inspect suspension and gate controls, including the positive means preventing accidental dumping. Load within the bucket rating and lift plan using the actual filled weight; keep workers clear of truck and bucket pinch points.
Verification: Operator and rigger check bucket identification, gate closure and load basis.
Why this belongs in the analysis: Concrete volume is not a substitute for total lifted weight.
3. Move the suspended bucket
Hazard: A swinging bucket or falling concrete can strike workers.
Control: Use qualified lift roles and agreed signals; clear the travel path and keep workers out from under the bucket. Control orientation by the planned method from a safe position, without wrapping a line around the body.
Verification: Lift lead verifies clearance before movement and monitors the route.
Why this belongs in the analysis: A nearby guide still needs separation from the moving load.
4. Position for discharge
Hazard: The gate operator can be trapped between the bucket and form.
Control: Bring the bucket to the planned position and maintain a stable operating relationship. Operate the gate from outside pinch and fall paths using the specified mechanism; do not push the suspended bucket by hand to force alignment.
Verification: Gate operator and crane operator confirm the stop/discharge signal before opening.
Why this belongs in the analysis: Discharge creates a new interface between hoisting and placement.
5. Place and close the gate
Hazard: Concrete surge or leaking discharge can overwhelm the receiving area or strike workers.
Control: Discharge in the planned increments while monitoring forms and access. Stop for form movement or loss of control; close and secure the gate before moving the bucket back through the route.
Verification: Foreperson monitors form response and gate operator confirms closure.
Why this belongs in the analysis: Gate closure must precede the return lift.
6. Land and secure the bucket
Hazard: A raised or unstable bucket can move during cleaning and maintenance.
Control: Land on its designated stable support, remove the hoisting exposure and secure gate and hazardous energy before servicing. Manage wet-concrete residue and hand over any equipment defects.
Verification: Operator confirms the landed safe state before cleanup personnel approach.
Why this belongs in the analysis: A suspended bucket is not a cleaning platform.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Use qualified lift roles and agreed signals; clear the travel path and keep workers out from under the bucket. Control orientation by the planned method from a safe position, without wrapping a line around the body. |
| Check that everything is ready. | Foreperson confirms form and reinforcement release, safe access and protected projections. Match the placement sequence to receiving capacity and keep unrelated workers outside the discharge zone. |
Decisions that change the analysis
Can workers ride the bucket to reach the form?
No. Provide separate suitable access. Bucket transport is a material-lifting task; this example excludes personnel transport and working beneath the raised bucket.
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
- Gate restraint fails or leakage cannot be controlled.
- Form movement, load-weight uncertainty or lifting clearance changes.
- A worker enters the load path or communication is lost.
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
- Applicable crane operator, signal-person and qualified-rigger roles for this lift.
- Bucket gate operation, footing access and wet-cement contact instruction.
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.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
