First, describe the work and worksite
A specialist glazing crew will install factory-fabricated safety-glass panels in released interior partition channels and retainers at ground level. Building users are kept outside the installation area until support and final retention are accepted. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The actual partition system establishes glass type, panel weight, channel anchorage, setting supports and final retention.
- The approved handling device is suitable for the actual panel surface and orientation.
- Moving doors, stair guards, balustrades, overhead glass, field glass modification and structural glass are excluded.
Questions before work
- What confirms the channel support and specified glass are compatible?
- How is the panel restrained before the final retainers are complete?
- Who controls access on both sides of the developing partition?
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 channels and installation area
Hazard: Unready channels or accessible work paths can expose occupants to falling glass.
Control: Glazing lead checks channel support, specified panel schedule and released layout against the actual system. Close access on both sides and establish the setting sequence; hold for support or glass-type uncertainty.
Verification: Lead verifies support documentation and the complete access boundary before delivery.
Why this belongs in the analysis: The panel depends on the partition supports before it becomes a barrier.
2. Inspect and prepare the panel
Hazard: Damaged edges or an incompatible attachment can cause breakage during pickup.
Control: Verify factory identification, weight and edge condition while the panel remains on protected stable supports. Check handling-device suitability and condition; remove damaged or unidentified panels from the installation sequence and apply assessed cut protection.
Verification: Handling lead checks panel condition and the device instructions before attachment.
Why this belongs in the analysis: A panel intended as safety glass still needs careful edge and load handling.
3. Move through the controlled route
Hazard: A large panel can strike workers or trap hands at a narrow interior passage.
Control: Use the planned device or team method with one movement lead and agreed stop signals. Clear the full panel envelope, protect hard-contact points and keep people outside its tip and pinch paths; stop rather than forcing an obstructed turn.
Verification: Movement lead walks the route and confirms receiving positions before pickup.
Why this belongs in the analysis: Interior room clearance must account for the moving panel, not only people.
4. Seat on specified supports
Hazard: An unretained panel can tip; hands can be crushed between glass and channel.
Control: Set from the designated positions using the actual support and setting-block arrangement. Keep handling support in place until required temporary restraint is verified; use positioning tools without placing fingers beneath or between closing surfaces.
Verification: Installer and handling lead check seating and restraint before changing support.
Why this belongs in the analysis: Seating the bottom edge does not establish complete retention.
5. Complete and verify retention
Hazard: Missing retainers or unsuitable packing can let the partition move after unrigging.
Control: Install the specified retainers and seals without substituting hard improvised packing or modifying tempered glass. Complete the actual system checks and obtain the designated release before removing handling or temporary support.
Verification: Glazing lead records support and retention findings for the installed panel.
Why this belongs in the analysis: Apparent alignment does not demonstrate the panel is secured.
6. Release the room interface
Hazard: Incomplete protection or unnoticed damage can expose building users.
Control: Inspect the completed section under its designated handover process, identify unfinished work and clean sharp waste. Communicate access status and required visibility markings; retain the boundary where acceptance remains unresolved.
Verification: Receiving building contact confirms the installed section and access restrictions.
Why this belongs in the analysis: A transparent partition creates an occupancy interface as well as an installation task.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Use the planned device or team method with one movement lead and agreed stop signals. Clear the full panel envelope, protect hard-contact points and keep people outside its tip and pinch paths; stop rather than forcing an obstructed turn. |
| Check that everything is ready. | Glazing lead checks channel support, specified panel schedule and released layout against the actual system. Close access on both sides and establish the setting sequence; hold for support or glass-type uncertainty. |
Decisions that change the analysis
Can the frameless-door example substitute for this partition?
It provides related glass handling background. A fixed partition has channel, setting-support and retention checks rather than hinges, patch fittings and swing testing. Use the actual fixed-panel system and keep doors outside this scope.
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
- Glass identity, condition or channel support is uncertain.
- Handling control or temporary restraint cannot be maintained.
- Retention findings, unexpected contact or occupant entry interrupt the sequence.
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 partition system support, panel seating and final-retention instruction.
- Glass handling-device or team demonstration, sharp-edge protection and stop 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.
Are these resources part of a paid course?
