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.

Your Frameless Glass Door 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. Release the opening and hardware
Possible hazards: Wrong fittings or inadequate support can cause a heavy door to detach.
Planned controls: Glazing lead checks leaf schedule, hardware compatibility, supporting structure and released opening. Establish a closed work zone and refer mismatched cutouts or supports before lifting.
Check before work: Installer compares actual components with the approved hardware instructions.
022. Inspect and stage the leaf
Possible hazards: Edge damage or unstable glass can cause breakage and cuts.
Planned controls: Inspect factory glass condition and identification and place on protected stable supports. Remove damaged or unidentified glass from the installation sequence; use assessed cut-resistant hand, arm, eye and foot protection.
Check before work: Handling lead checks edges and staging restraint before movement.
033. Support the leaf in position
Possible hazards: A tilting door can crush fingers or fall before hardware is complete.
Planned controls: Use the planned handling and temporary support method sized for the leaf. Keep workers outside the tip and pinch paths and protect glass edges from hard contact; do not balance the leaf with an improvised foot stop.
Check before work: Handling lead verifies support before fitters approach.
044. Assemble fittings and retention
Possible hazards: Uneven clamping or missing gaskets can damage glass or allow slippage.
Planned controls: Fit the specified gaskets, fasteners and hardware in the instructed sequence and tighten to the actual system criteria. Do not modify tempered glass or substitute unapproved fitting parts.
Check before work: Installer records checks against the hardware instructions before removing temporary support.
055. Test controlled movement
Possible hazards: A freely swinging leaf can strike workers or trap hands.
Planned controls: Clear the swing area and test from controlled positions only after support and retention are verified. Check required stops, clearances and closer settings; hold occupant access for unsafe movement or interference.
Check before work: Glazing lead observes the full swing and safe stop function.
066. Release the door for use
Possible hazards: Unfinished retention, debris or uncommunicated restrictions can expose occupants.
Planned controls: Complete the designated installation check, collect sharp waste and mark any unresolved restrictions. Transfer hardware settings and maintenance instructions to the responsible building contact.
Check before work: Lead records the actual handover and remaining actions.
Example scope and starting conditions
A glazing crew will fit a factory-fabricated tempered-glass interior door leaf to a released opening using the specified patch fittings or hinges and controlled support. The opening is closed to occupants during installation. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The approved hardware system matches door thickness, weight, factory cutouts and supporting structure.
- Temporary leaf support remains until the complete suspension and retention checks are finished.
- Glass cutting or drilling, shower enclosures, automatic operators and fitting to an unreleased supporting panel are excluded.
Know when to pause
- Glass damage or hardware/cutout mismatch.
- Temporary support or specified fitting criteria cannot be met.
- Uncontrolled swing, interference or occupant entry into the work zone.
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
- Do the leaf, factory cutouts and hardware match the approved system?
- What supports the door while fittings are assembled?
- How are swing, pinch and occupant access controlled during testing?
Training and qualifications to confirm
- Actual door-hardware installation, temporary support and retention verification.
- Glass edge protection, team handling and controlled door-swing testing.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
May the installer enlarge a factory cutout in tempered glass?
No. Stop and obtain the correct factory-fabricated leaf and hardware arrangement. This example provides no on-site cutting or drilling procedure for tempered glass.
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 opening and hardware
Hazard: Wrong fittings or inadequate support can cause a heavy door to detach.
Control: Glazing lead checks leaf schedule, hardware compatibility, supporting structure and released opening. Establish a closed work zone and refer mismatched cutouts or supports before lifting.
Verification: Installer compares actual components with the approved hardware instructions.
Why this belongs in the analysis: A frameless appearance does not remove the need for a defined support system.
2. Inspect and stage the leaf
Hazard: Edge damage or unstable glass can cause breakage and cuts.
Control: Inspect factory glass condition and identification and place on protected stable supports. Remove damaged or unidentified glass from the installation sequence; use assessed cut-resistant hand, arm, eye and foot protection.
Verification: Handling lead checks edges and staging restraint before movement.
Why this belongs in the analysis: Tempered glass edge damage can affect the whole leaf.
3. Support the leaf in position
Hazard: A tilting door can crush fingers or fall before hardware is complete.
Control: Use the planned handling and temporary support method sized for the leaf. Keep workers outside the tip and pinch paths and protect glass edges from hard contact; do not balance the leaf with an improvised foot stop.
Verification: Handling lead verifies support before fitters approach.
Why this belongs in the analysis: The installation is not yet supported by its final hinges.
4. Assemble fittings and retention
Hazard: Uneven clamping or missing gaskets can damage glass or allow slippage.
Control: Fit the specified gaskets, fasteners and hardware in the instructed sequence and tighten to the actual system criteria. Do not modify tempered glass or substitute unapproved fitting parts.
Verification: Installer records checks against the hardware instructions before removing temporary support.
Why this belongs in the analysis: The glass/hardware interface is part of the door’s load path.
5. Test controlled movement
Hazard: A freely swinging leaf can strike workers or trap hands.
Control: Clear the swing area and test from controlled positions only after support and retention are verified. Check required stops, clearances and closer settings; hold occupant access for unsafe movement or interference.
Verification: Glazing lead observes the full swing and safe stop function.
Why this belongs in the analysis: A door that hangs securely can still create a moving pinch hazard.
6. Release the door for use
Hazard: Unfinished retention, debris or uncommunicated restrictions can expose occupants.
Control: Complete the designated installation check, collect sharp waste and mark any unresolved restrictions. Transfer hardware settings and maintenance instructions to the responsible building contact.
Verification: Lead records the actual handover and remaining actions.
Why this belongs in the analysis: Use release follows installation and movement checks, not appearance.

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.
