First, describe the work and worksite
A glazing crew will assemble and mechanically anchor empty aluminum storefront framing in a released ground-floor building opening. The frame is handed over for a later glazing crew; no glass or doors are installed in this sequence. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Released shop drawings establish frame members, anchorage, support and drainage details for the actual system.
- Drilling locations and substrate conditions are accepted before anchors are placed.
- Glass setting, door hanging, structural silicone, overhead suspended framing and alteration of an occupied entrance are excluded.
Questions before work
- Which supports and anchor details apply to this opening?
- Where must sill drainage and movement remain functional?
- What keeps the unanchored assembly stable while workers fix it?
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 opening and frame system
Hazard: Wrong supports or concealed services can cause anchor failure or a drilling strike.
Control: Glazing lead compares the released opening, substrate investigation and frame schedule with current shop drawings. Identify permissible drilling positions and structural support; hold installation where the receiving condition differs.
Verification: Lead records the opening and anchorage release before unloading members.
Why this belongs in the analysis: A frame sized to fit is not yet a verified support system.
2. Stage and inspect frame members
Hazard: Long sections can tip or cut workers; unidentified components can create a weak assembly.
Control: Store members on stable supports outside access, protect exposed ends and verify part identity and condition. Use assessed handling aids and sharp-edge protection; segregate damaged sections rather than concealing distortion during assembly.
Verification: Material lead checks member marks, supports and the transfer route.
Why this belongs in the analysis: Empty aluminum framing still creates handling and edge exposures.
3. Assemble from stable access
Hazard: An unsecured assembly can rotate or trap hands at joints.
Control: Assemble the specified joints on suitable supports with the approved connectors and tools. Keep hands outside closing joints and install planned temporary restraint before raising or moving the assembly; do not use loose props as its release basis.
Verification: Assembly lead verifies connections and restraint before transfer.
Why this belongs in the analysis: Assembly support must remain effective as the frame changes orientation.
4. Position and anchor the frame
Hazard: An unrestrained frame can fall; drilling can expose workers to dust or hidden services.
Control: Position with the planned team or handling device and retain temporary support. Drill only released locations using applicable dust controls; install specified shims and anchors without inventing anchor spacing or tightening criteria.
Verification: Installer checks anchor installation against actual system and substrate requirements.
Why this belongs in the analysis: The frame needs support while its permanent load path is being completed.
5. Verify support and drainage
Hazard: Incomplete anchorage or blocked drainage can leave an unsafe or unsuitable glazing support.
Control: Complete the designated support, alignment and fastening checks before removing temporary restraint. Preserve sill outlets, flashing and specified movement accommodation; refer interference instead of filling every apparent gap with sealant.
Verification: Glazing lead records connection and drainage findings at the handover points.
Why this belongs in the analysis: Closing a gap can defeat a designed drainage or movement detail.
6. Hand over for glazing
Hazard: A following crew may load an incomplete frame or assume door access is released.
Control: Identify unfinished anchors, glazing supports and access restrictions. Remove sharp scrap and transfer the actual frame acceptance and drainage status to the glazing lead; keep the opening controlled until its next-stage release.
Verification: Receiving lead confirms frame status and remaining actions before glass delivery.
Why this belongs in the analysis: Frame installation and glass installation require separate handovers.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Assemble the specified joints on suitable supports with the approved connectors and tools. Keep hands outside closing joints and install planned temporary restraint before raising or moving the assembly; do not use loose props as its release basis. |
| Check that everything is ready. | Glazing lead compares the released opening, substrate investigation and frame schedule with current shop drawings. Identify permissible drilling positions and structural support; hold installation where the receiving condition differs. |
Decisions that change the analysis
Does a plumb frame mean it is ready for glass?
No. Confirm the actual anchorage, sill and glazing support, drainage details and designated handover. Alignment alone supplies no connection acceptance or permission to load the frame.
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
- Opening, anchorage or concealed-service information is incomplete.
- Frame movement, damaged members or unresolved connection findings.
- Drainage, movement accommodation or protected access cannot be retained.
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 storefront frame assembly, substrate anchorage and temporary-restraint instruction.
- Applicable anchor-drilling dust controls and frame handling 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.
