Step 1 of 4 · Working draft
Your job
Tell Jenkins what you’re planning and where the work will happen. Use the actual job details.
Use the published example’s suggestions when they fit your task, or write your own steps. These are planned controls, not verified worksite conditions.
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.
Walk through the plan with the people doing the work. Resolve missing controls and agree who checks them. Moving to the next step does not approve the work.
Confirm people, equipment and emergency arrangements
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.
Print your own JHA by signing in, or contribute the selected structured categories as a guest. Signing in does not require research participation. Written job details are processed to prepare your export and are stored on our server only if you save to your private company library.
Research purpose, data fields, retention and withdrawal · Privacy notice
Sign-in uses a free account. Your tab draft is retained for the return from sign-in.
Hosted organization saving requires active jSMS access and a company workspace. View jSMS plans.
The export uses landscape pages, task-only continuation pages and a Page X of Y footer in current Chrome or Edge. Review every page. Opening an export is not proof that the JHA was printed or used. The PDF includes its research choice and reference; the private withdrawal link stays in the export’s screen-only receipt.

Your entries stay in this working draft as you move between steps. Required field checks, employer review and work authorization remain separate.
Your Roof Insulation and Cover Board Installation JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Accept the deck and layout
Possible hazards: Unready deck or concealed services can cause collapse or fastening injury.
Planned controls: 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.
Check before work: Lead compares the roof handover with the approved assembly details.
022. Receive and stage boards
Possible hazards: Concentrated stock can overload the deck; lightweight sheets can blow away.
Planned controls: 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.
Check before work: Material lead checks stack stability and roof-load limits.
033. Cut and handle the product
Possible hazards: Board dust, fibers or sharp cutters can injure workers.
Planned controls: 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 before work: Assigned cutter checks product identity and control method before work.
044. Lay boards in sequence
Possible hazards: Loose boards can move or hide an opening, causing a fall.
Planned controls: 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.
Check before work: Foreperson checks opening protection and sheet restraint as each area advances.
055. Install specified fasteners
Possible hazards: Wrong fasteners or unapproved penetration can cause system failure or strike services.
Planned controls: 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.
Check before work: Installer records the actual checks against system details.
066. Hand over for membrane work
Possible hazards: Loose boards, gaps or unfinished fixing can expose the membrane crew.
Planned controls: 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.
Check before work: Receiving lead confirms the accepted area and restrictions.
Example scope and starting conditions
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.
Know when to 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.
Free example and template
No account required. The worked example contains planned controls. The blank template is for your own work; neither includes fabricated inspection results, signatures or approval.

For managers
Does the team have what it needs to carry out the plan? Give the crew time, equipment and support, and make it clear who will resolve anything that is missing.
Manager checks and supporting resources
Confirm the people doing the work have the time, equipment, information and support to carry out the plan. Agree who checks the controls and who resolves open actions.
Questions to resolve 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?
Training and qualifications to confirm
- Actual insulation/board cutting, exposure controls and mechanical fastening instruction.
- Roof-load staging and applicable edge/opening fall-protection training.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
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.

Task-by-task control and verification rationale
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.
Compare control wording
| 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. |
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.
