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.

Your Wood Wall Panel Assembly JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Release the panel layout
Possible hazards: A wrong drawing or overcrowded assembly space can create handling conflicts and an unusable panel.
Planned controls: Framing lead verifies the current panel drawing and released slab area. Mark the panel boundary, member positions and opening detail, with clear handling and escape routes. Resolve changed dimensions or missing design information before components are assembled.
Check before work: Lead compares the marked layout with the panel drawing before material enters.
022. Stage prepared components
Possible hazards: Long stock, unstable stacks and repeated carrying can injure workers or obstruct safe movement.
Planned controls: Identify and inspect the precut plates, studs and opening members. Stage manageable quantities on stable supports near use, using a cart or planned assistance. Keep sharp hardware and scrap contained and reject damaged or unidentified components.
Check before work: Material lead checks member marks, condition and clear routes.
033. Position plates and studs
Possible hazards: Members can roll or close onto fingers while the crew adjusts a flat assembly.
Planned controls: Use the planned jig or temporary restraints on the released surface. Agree coordinated movements, keep hands outside closing joints and use suitable positioning tools. Preserve stable support rather than holding a loose member in the fastener path.
Check before work: Assembly lead checks support and helper positions before fastening begins.
044. Build the designed opening
Possible hazards: Incorrect jack, king or header arrangement can leave the wall without its intended load path.
Planned controls: Assemble the identified rough-opening components under the current detail with their specified bearing and connection arrangement. Maintain support while connections are made; do not improvise a larger opening, substitute a header or notch a member to resolve a fit problem.
Check before work: Lead checks concealed opening components and connections before the frame is closed.
055. Complete connections and geometry
Possible hazards: Unfinished fastening or unintended tool discharge can injure the crew and leave a weak panel.
Planned controls: Complete the drawing-specified connections using the actual fastening-tool procedure and safe positions. Keep helpers outside discharge paths, isolate the tool before required adjustments, and verify panel geometry without standing it up or removing necessary assembly restraints.
Check before work: Lead compares connection completion and panel dimensions with current acceptance criteria.
066. Secure the panel for handover
Possible hazards: An unfinished or unstable panel can be moved or raised by another crew without its restrictions.
Planned controls: Leave the panel in its planned flat, restrained staging condition, clear waste and identify remaining connections or defects. Transfer its identity, condition and handling restrictions to the raising lead; the separate wall-raising release governs any lift or tilt.
Check before work: Receiving lead confirms the panel record before authorizing the next operation.
Example scope and starting conditions
A framing crew will assemble one wood stud wall panel flat on a released ground-floor slab using precut components and a designed door rough opening. The completed panel remains flat and restrained for a separate raising operation. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The current panel drawing identifies dimensions, member marks, opening components, connections and the required assembly support.
- The slab, assembly space and permitted material loads are released; a controlled fastening station has identified tool and discharge boundaries.
- Wall raising, sheathing, field design, powered stock cutting and assembly of the separate floor-opening frame are excluded.
Know when to pause
- Panel dimensions, opening detail or member identification differs from the released drawing.
- A support, jig or helper position cannot keep hands outside movement and fastener paths.
- The handover requires raising, alteration or an unresolved connection.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting.

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
- How are panel identity and the current opening detail confirmed before assembly?
- Which supports and restraints keep the panel stable during fastening and handover?
- Where can the helper work outside fastener discharge and closing-member paths?
Training and qualifications to confirm
- The actual panel drawing, opening components, assembly restraints and connection-verification sequence.
- Task-specific material handling and the selected fastening tool’s discharge, isolation and safe-helper arrangements.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Does the pneumatic-nail-gun example already cover this panel?
It teaches one fastening tool’s safe operating cycle on supported components. This analysis produces and verifies an identified wall panel, including its layout and rough opening, before the separate wall-raising operation.
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. Release the panel layout
Hazard: A wrong drawing or overcrowded assembly space can create handling conflicts and an unusable panel.
Control: Framing lead verifies the current panel drawing and released slab area. Mark the panel boundary, member positions and opening detail, with clear handling and escape routes. Resolve changed dimensions or missing design information before components are assembled.
Verification: Lead compares the marked layout with the panel drawing before material enters.
Why this belongs in the analysis: Panel identity and geometry precede fastening-tool selection.
2. Stage prepared components
Hazard: Long stock, unstable stacks and repeated carrying can injure workers or obstruct safe movement.
Control: Identify and inspect the precut plates, studs and opening members. Stage manageable quantities on stable supports near use, using a cart or planned assistance. Keep sharp hardware and scrap contained and reject damaged or unidentified components.
Verification: Material lead checks member marks, condition and clear routes.
Why this belongs in the analysis: Prepared stock still requires controlled handling and identification.
3. Position plates and studs
Hazard: Members can roll or close onto fingers while the crew adjusts a flat assembly.
Control: Use the planned jig or temporary restraints on the released surface. Agree coordinated movements, keep hands outside closing joints and use suitable positioning tools. Preserve stable support rather than holding a loose member in the fastener path.
Verification: Assembly lead checks support and helper positions before fastening begins.
Why this belongs in the analysis: The component should be restrained by the method rather than by a helper’s fingers.
4. Build the designed opening
Hazard: Incorrect jack, king or header arrangement can leave the wall without its intended load path.
Control: Assemble the identified rough-opening components under the current detail with their specified bearing and connection arrangement. Maintain support while connections are made; do not improvise a larger opening, substitute a header or notch a member to resolve a fit problem.
Verification: Lead checks concealed opening components and connections before the frame is closed.
Why this belongs in the analysis: A square-looking opening does not establish structural support.
5. Complete connections and geometry
Hazard: Unfinished fastening or unintended tool discharge can injure the crew and leave a weak panel.
Control: Complete the drawing-specified connections using the actual fastening-tool procedure and safe positions. Keep helpers outside discharge paths, isolate the tool before required adjustments, and verify panel geometry without standing it up or removing necessary assembly restraints.
Verification: Lead compares connection completion and panel dimensions with current acceptance criteria.
Why this belongs in the analysis: This is a complete component check, not just a trigger-operation demonstration.
6. Secure the panel for handover
Hazard: An unfinished or unstable panel can be moved or raised by another crew without its restrictions.
Control: Leave the panel in its planned flat, restrained staging condition, clear waste and identify remaining connections or defects. Transfer its identity, condition and handling restrictions to the raising lead; the separate wall-raising release governs any lift or tilt.
Verification: Receiving lead confirms the panel record before authorizing the next operation.
Why this belongs in the analysis: Assembly completion does not authorize wall erection.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Use the planned jig or temporary restraints on the released surface. Agree coordinated movements, keep hands outside closing joints and use suitable positioning tools. Preserve stable support rather than holding a loose member in the fastener path. |
| Check that everything is ready. | Framing lead verifies the current panel drawing and released slab area. Mark the panel boundary, member positions and opening detail, with clear handling and escape routes. Resolve changed dimensions or missing design information before components are assembled. |
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.
