First, describe the work and worksite
A glazing crew will install specified glass into a released ground-level storefront frame using a planned handling method, setting blocks and the required retention system. This fictional learning example records planned controls; it supplies no actual inspections or work authorization.
- Frame anchorage, glass identity, clearances and setting details are released by the system documents.
- Both sides of the opening can be isolated while the pane remains supported.
- This excludes curtain walls, elevated glazing, large panel hoisting and damaged-glass removal.
Questions before work
- What confirms frame readiness and the correct glass?
- How will the pane remain supported until retention is complete?
- Which system details govern setting blocks, clearances and seals?
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. Accept the frame and glass
Hazard: An incomplete frame or wrong pane can fail or create an unsafe fit.
Control: Lead checks frame release, glass marks and setting details against current documents. Hold damaged material, loose anchors or unresolved clearances.
Verification: Compare the opening and pane with the installation record.
Why this belongs in the analysis: A pane that fits visually may still be the wrong unit.
2. Prepare both sides of the opening
Hazard: People can enter the pane’s fall path or be struck by tools.
Control: Isolate both sides, keep exits available and prepare a handling route and stable material supports.
Verification: Lead walks the route and checks the boundary before moving glass.
Why this belongs in the analysis: The installation needs a protected receiving area.
3. Inspect handling equipment and prepare the setting
Hazard: An unsuitable handling device or misplaced block can drop or damage glass.
Control: Use the assessed panel-handling method and check devices against actual instructions. Prepare the specified blocks, retainers and tools before lifting.
Verification: Lead checks equipment suitability and setting materials.
Why this belongs in the analysis: Support details must be ready before the pane enters the opening.
4. Position the pane
Hazard: Glass can cut workers, trap fingers or strike the frame.
Control: Coordinate movement under one leader, keep hands out of pinch paths and land on the specified setting supports without forcing a fit.
Verification: Leader monitors clearance and support; pause for resistance or loss of control.
Why this belongs in the analysis: Forcing a pane changes both the exposure and installation quality.
5. Complete retention and seals
Hazard: Releasing handling support too soon can let the pane fall; sealants can expose workers.
Control: Install the required retention before releasing support. Apply the specified seals with actual product chemical controls and protect unfinished edges.
Verification: Lead verifies independent retention and the product method before release.
Why this belongs in the analysis: A seated pane may still need retainers to remain stable.
6. Inspect and hand over
Hazard: Missing retainers, loose waste or cure restrictions can endanger occupants.
Control: Check the system’s required completion items, collect waste and communicate product cure and access restrictions. Keep the boundary until authorized release.
Verification: Lead reconciles completed and open items with the receiving supervisor.
Why this belongs in the analysis: The handover must state actual retention and access status.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Be careful around the equipment. | Use the assessed panel-handling method and check devices against actual instructions. Prepare the specified blocks, retainers and tools before lifting. |
| Check the area before starting. | Lead checks frame release, glass marks and setting details against current documents. Hold damaged material, loose anchors or unresolved clearances. |
Decisions that change the analysis
Does this also cover curtain-wall installation?
No. Curtain walls introduce different anchorage, lifting, access and temporary-support interfaces. The storefront frame is released before this ground-level glass-setting task.
What must be recorded before this example is used on a job?
Replace the scenario with the actual work, identify additional hazards with the crew, and record the applicable instructions, responsible people, inspection findings, unresolved actions and required authorization. A planned verification is not an inspection result.
Agree when the crew will pause
- Frame release, pane identity or fit differs.
- Handling support or retention cannot be completed.
- The job changes to elevated or heavy-panel glazing.
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 glass-setting system, handling method and retention sequence.
- Sealant hazards and recognizing frame or pane deviations.
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 be used as a JSA?
Use the Task | Hazard | Control structure if it meets the employer’s format. Adapt the boundaries, controls, verification and records to the actual job.
Does this provide a completed USACE AHA?
No. Use the project’s required AHA process, risk method, supporting fields and acceptance requirements. The existing formwork AHA explains the additional structure.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
