First, describe the work and worksite
A roofing crew will lay and mechanically fasten specified insulation and cover boards on a released low-slope steel roof deck before membrane installation. Materials arrive through a separate approved hoisting plan. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Deck capacity, fastener locations, hidden-service clearance and board arrangement are released for this assembly.
- The product SDS and cutting instructions establish dust, fiber and skin controls for the actual boards.
- Adhesive application, structural deck repair, membrane installation and using loose boards as opening covers are excluded.
Questions before work
- What verifies the deck and fastening locations for this assembly?
- How are lightweight boards restrained against wind before fixing?
- Which dust/fiber controls match the actual insulation and cover board?
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 deck and layout
Hazard: Unready deck or concealed services can cause collapse or fastening injury.
Control: Roofing lead checks deck release, assembly layout, fastener penetration limits and load locations. Identify openings and maintain their separate protection; hold work where service or support information is incomplete.
Verification: Lead compares the roof handover with the approved assembly details.
Why this belongs in the analysis: The board layer cannot repair an unresolved deck condition.
2. Receive and stage boards
Hazard: Concentrated stock can overload the deck; lightweight sheets can blow away.
Control: Land materials only at permitted load locations and keep bundles restrained for conditions. Separate delivery from laying crews and retain access and fire/escape routes.
Verification: Material lead checks stack stability and roof-load limits.
Why this belongs in the analysis: Low-weight individual boards can still form a heavy concentrated stack.
3. Cut and handle the product
Hazard: Board dust, fibers or sharp cutters can injure workers.
Control: Use the actual product’s designated cutting method, dust controls and assessed protection at a safe station. Support sheets, keep hands outside the cut path and collect offcuts without creating airborne dust.
Verification: Assigned cutter checks product identity and control method before work.
Why this belongs in the analysis: Different board compositions need different exposure controls.
4. Lay boards in sequence
Hazard: Loose boards can move or hide an opening, causing a fall.
Control: Place the approved layers from protected positions, maintain actual opening covers/guards and secure laid material against movement. Never substitute a loose insulation sheet for a rated secured cover.
Verification: Foreperson checks opening protection and sheet restraint as each area advances.
Why this belongs in the analysis: A visually covered roof may still contain an unprotected hole.
5. Install specified fasteners
Hazard: Wrong fasteners or unapproved penetration can cause system failure or strike services.
Control: Use the released fastening pattern, plates and penetration criteria. Follow required substrate checks and stop for abnormal deck response; do not increase screw length to solve a fit issue without approval.
Verification: Installer records the actual checks against system details.
Why this belongs in the analysis: The attachment must match the deck and hidden conditions.
6. Hand over for membrane work
Hazard: Loose boards, gaps or unfinished fixing can expose the membrane crew.
Control: Complete the designated substrate check, clear offcuts and secure unfinished areas for wind/weather. Transfer board, fastening and opening status to the membrane lead with remaining actions.
Verification: Receiving lead confirms the accepted area and restrictions.
Why this belongs in the analysis: The membrane crew needs a specific substrate handover.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Use the actual product’s designated cutting method, dust controls and assessed protection at a safe station. Support sheets, keep hands outside the cut path and collect offcuts without creating airborne dust. |
| Check that everything is ready. | Roofing lead checks deck release, assembly layout, fastener penetration limits and load locations. Identify openings and maintain their separate protection; hold work where service or support information is incomplete. |
Decisions that change the analysis
Can loose cover board protect a roof hole temporarily?
No. Keep the separately selected secured, load-suitable opening cover or guard in place. Insulation or cover-board appearance alone does not establish the required opening protection.
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
- Deck/service information, fastener response or loading changes.
- Wind moves loose boards or opening protection is obscured.
- Product identity, cutting controls or substrate acceptance is unresolved.
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 insulation/board cutting, exposure controls and mechanical fastening instruction.
- Roof-load staging and applicable edge/opening fall-protection training.
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?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
