First, describe the work and worksite
A glazing crew will install a factory-cut vertical interior mirror on a released wall with the specified mechanical supports and compatible mirror adhesive. The wall area remains closed to occupants until the required support, bonding and handover conditions are satisfied. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The approved assembly identifies mirror backing, wall finish, supports, retainers and adhesive compatibility.
- Mechanical support remains during and after installation as required by the selected assembly and adhesive instructions.
- Field cutting, overhead mirrors, unknown wall coatings and improvised adhesive-only retention are excluded.
Questions before work
- Do the mirror backing and actual wall finish suit the selected adhesive?
- Which permanent mechanical supports and temporary handling supports carry the mirror?
- What evidence and cure conditions permit the installation to be handed over?
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 wall and support arrangement
Hazard: Weak wall fixing or incompatible adhesive can allow the mirror to detach.
Control: Glazing lead verifies substrate condition, approved mechanical support and mirror/adhesive compatibility. Obtain required surface tests and installation criteria from the actual product documents; hold for unknown backing or wall finishes.
Verification: Lead compares actual materials and fixing locations with the approved assembly.
Why this belongs in the analysis: Mirror backing and wall chemistry affect a concealed bond.
2. Inspect and stage the mirror
Hazard: Edge damage or unstable staging can cause glass breakage and cuts.
Control: Check mirror identity, dimensions and edge condition while it remains on protected stable supports. Confirm the handling method and exposed-edge protection; segregate damaged pieces and keep the full transfer route clear.
Verification: Handling lead inspects the mirror and staging before pickup.
Why this belongs in the analysis: The reflective surface does not show every vulnerable backing or edge condition.
3. Install supports and prepare surfaces
Hazard: Drilling can strike concealed services; cleaners can expose workers or damage finishes.
Control: Fix the specified supports at released locations with required dust controls. Use only the compatible preparation method, with product labels, ventilation and assessed skin/eye protection; keep cleaners away from incompatible mirror backing.
Verification: Installer records support checks and verifies the selected preparation materials.
Why this belongs in the analysis: Surface preparation and mechanical support are separate readiness checks.
4. Apply adhesive and position the mirror
Hazard: Slipping glass or a misapplied bond can expose the setting crew and later occupants.
Control: Apply the actual product pattern within its permitted working conditions and position with planned handling support. Seat on the specified mechanical supports and install retainers; keep hands outside closing gaps and do not substitute a general construction adhesive.
Verification: Glazing lead checks product identity, seating and retention before handling support changes.
Why this belongs in the analysis: Initial tack does not replace the defined support arrangement.
5. Protect the bonding period
Hazard: Early disturbance or changed curing conditions can compromise the bond.
Control: Maintain the product-required support, access restrictions and curing environment. Record installation conditions and obtain the designated cure/acceptance determination; do not infer release from a dry surface or another product’s cure time.
Verification: Assigned lead reviews actual conditions and unresolved bonding findings.
Why this belongs in the analysis: Surface skinning and completed bond performance are different observations.
6. Hand over the finished wall
Hazard: Removed retainers or hidden unfinished work can expose occupants after installation.
Control: Complete the designated support and finish inspection, remove sharp waste and communicate any continuing restrictions. Transfer support/adhesive information to the building contact and retain permanent mechanical support required by the assembly.
Verification: Receiving contact confirms acceptance status and maintenance information.
Why this belongs in the analysis: Curing does not authorize removal of permanent mechanical support.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Fix the specified supports at released locations with required dust controls. Use only the compatible preparation method, with product labels, ventilation and assessed skin/eye protection; keep cleaners away from incompatible mirror backing. |
| Check that everything is ready. | Glazing lead verifies substrate condition, approved mechanical support and mirror/adhesive compatibility. Obtain required surface tests and installation criteria from the actual product documents; hold for unknown backing or wall finishes. |
Decisions that change the analysis
May the supports be removed when the adhesive feels firm?
Only temporary supports may be removed under the actual assembly’s release criteria. Keep permanent supports and retainers in place. The referenced mirror adhesive specifically requires mechanical support during and after installation; apparent surface firmness is not a release.
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
- Unknown backing, wall finish or missing compatibility evidence.
- Mirror damage, support movement or unsuitable preparation conditions.
- Curing conditions, occupant access or retention requirements change.
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
- Mirror backing and adhesive compatibility, mechanical retention and actual product acceptance instruction.
- Glass handling and chemical preparation instruction with applicable hazard 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.
