First, describe the work and worksite
A glazing crew installs factory-fabricated overhead panes on an accepted framed entrance canopy. The project specifies its laminated safety-glass build-up and retention system; the entrance is closed and approved access and handling equipment are available. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- One framed entrance-canopy glazing operation only; no frameless point fixing, supporting-frame erection or walk-on-glass access.
- The designer has accepted canopy loads, glazing type, pane dimensions, supporting frame and permanent retention.
- A separate route serves building users while the canopy and area below remain controlled.
Questions before work
- Who releases the actual glass build-up, supporting frame and designed overhead retention?
- How are panes held during positioning and how is temporary restraint released after retention acceptance?
- Can every fixing be reached from accepted equipment without walking or leaning on canopy glass?
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 overhead glazing package
Hazard: The wrong pane or unaccepted support can fail above an occupied entrance.
Control: Match pane labels and frame conditions to the accepted design. Resolve damage, missing bearing details and retention requirements; record the supporting-frame release before staging glass.
Verification: Glazing lead confirms the design revision, pane identity and frame acceptance are available together.
Why this belongs in the analysis: A canopy needs a designed overhead assembly; a pane that fits the opening may still be unsuitable.
2. Close the entrance and prepare access
Hazard: People can enter beneath a lifted pane; improvised reach positions expose workers to falls.
Control: Close the full handling and dropped-object area, arrange the alternate entrance and verify the accepted lift and access positions. Keep the platform and canopy support duties separate.
Verification: Assigned observer checks the closure and communication before the first pane leaves its rack.
Why this belongs in the analysis: A sign at the door does not control people entering the lift path from another approach.
3. Inspect and prepare the pane-handling system
Hazard: Contaminated contact surfaces, damaged edges or an unsuitable lifter can release overhead glass.
Control: Inspect pane edges and the actual handling device; confirm compatibility with the pane surface and orientation. Plan the supported handoff, clear the path and use the specified device checks.
Verification: Handler records device condition and pane suitability against its operating instructions.
Why this belongs in the analysis: A device suitable for upright transport may need a different approved arrangement for overhead positioning.
4. Position the pane on designed bearings
Hazard: A moving pane can trap hands, strike the frame or remain unsupported when the lifter is released.
Control: Move on agreed commands with everyone outside crush points and below-load exposure. Locate the pane on its specified bearings and maintain the designed temporary handling restraint.
Verification: Glazing lead confirms seating and stable interim restraint before the next fixing task begins.
Why this belongs in the analysis: The permanent support path must be established while the handling system still controls the pane.
5. Complete overhead retention and seals
Hazard: Incomplete clips or bars can permit a pane to slide; sharp tools and sealants create exposure.
Control: From accepted access, install the designed retainers and check their actual fastening criteria. Complete specified gaskets and seals without forcing glass edges; follow product handling and ventilation requirements.
Verification: Record retention acceptance and glass condition before authorizing the controlled handling-device release.
Why this belongs in the analysis: A seal or gasket cannot be credited as structural retention unless the accepted design gives it that role.
6. Inspect and reopen the entrance
Hazard: Loose hardware or concealed damage may remain over people after the crew leaves.
Control: Inspect the accepted pane and retention, remove loose materials and record unfinished interfaces. Keep the entrance closed until the responsible person accepts the overhead assembly and access removal.
Verification: Supervisor records separate glazing acceptance and entrance reopening decisions.
Why this belongs in the analysis: The public route is released only after the overhead condition has been checked.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Inspect pane edges and the actual handling device; confirm compatibility with the pane surface and orientation. Plan the supported handoff, clear the path and use the specified device checks. |
| Check that everything is ready. | Match pane labels and frame conditions to the accepted design. Resolve damage, missing bearing details and retention requirements; record the supporting-frame release before staging glass. |
Decisions that change the analysis
Can the crew stand on installed panes to finish the canopy?
No. This example uses accepted access equipment and treats the canopy glazing as overhead glass, not a work platform. A walk-on assembly would need its own designed system and work plan.
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
- Pause for chipped glass, disputed frame acceptance, handling-device alarms, changed weather or anyone entering below.
- Stop and obtain a new plan for point-fixed panes, unsupported access or changes to the specified overhead assembly.
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 crew on overhead pane handling, permanent retention acceptance and the specific canopy design boundaries.
- Verify the actual lift and access operator competencies and practice entrance closure and stop signals.
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.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
