Let’s build your JHA.
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 Adhesive Rebar Dowel 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 connection design
Possible hazards: Wrong bars, embedment or an unsuitable base material can create a fastening that later fails under load.
Planned controls: Installation lead compares the released bar and hole schedule with the actual concrete and approved adhesive system. Obtain the required inspection arrangements; hold undocumented holes or conditions outside the design and product approval.
Check before work: Lead checks hole identification, schedule and supporting release before preparation.
022. Prepare the installation station
Possible hazards: Adhesive contact, splash or unexpected movement of long bars can injure nearby workers.
Planned controls: Arrange labeled products, current SDS, washing supplies and specified hand and eye protection. Support the bars, separate the work from passersby and establish a controlled dispensing/waste area with product-required ventilation.
Check before work: Foreperson checks chemical controls and bar-handling space before packs are opened.
033. Verify and clean receiving holes
Possible hazards: Dust or unsuitable hole condition can impair bonding; cleaning can expose the crew to airborne silica.
Planned controls: Installer verifies the specified hole dimensions and condition, then uses the actual system’s approved cleaning tools and method. Assess silica exposure for that method; do not substitute a quick air blast or assume vacuuming alone satisfies the product instructions.
Check before work: Installer records the accepted hole condition and cleaning method for the installation review.
044. Prepare and dispense adhesive
Possible hazards: Expired material, incorrect mixing or chemical leakage can harm people and leave an unreliable connection.
Planned controls: Check product identity, storage condition, expiration, dispenser and mixing nozzle against instructions. Follow the specified initial discard and filling method while controlling splash and waste; stop for damage or inconsistent material.
Check before work: Installer verifies pack identity and dispensing readiness before filling each released hole.
055. Insert bars and protect the cure
Possible hazards: A displaced bar or early load can disturb the adhesive; exposed ends can create impalement exposure.
Planned controls: Mark the specified embedment and install bars by the approved method within actual working limits. Maintain required bar support and movement restrictions throughout the product-specific cure; guard fall-onto protruding steel exposures.
Check before work: Installer records bar position, substrate conditions and installation times; lead checks protection.
066. Record and hand over restrictions
Possible hazards: Another crew can use an unaccepted dowel as a handle or load an incompletely cured connection.
Planned controls: Mark unreleased connections and transfer installation records, cure restrictions and unresolved findings to the responsible reviewer. Loading or further connection work proceeds only after its required acceptance and release; dispose of waste under product and site arrangements.
Check before work: Lead confirms the receiving crew understands the marked restrictions and outstanding review.
Example scope and starting conditions
A repair crew will install engineer-specified reinforcing starter bars into already drilled and released horizontal holes in a ground-level concrete foundation face. The selected adhesive system and installation records govern hole preparation, placement and cure restrictions. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The actual bar schedule, embedment, concrete condition and adhesive approval must be established by the project design.
- Hole drilling and structural penetration clearance are complete and separately documented; receiving a hole does not prove it meets adhesive installation criteria.
- This is partial coverage of drilling and dowel installation. New drilling, overhead bars, crack injection, pull testing and loading before authorized release are excluded.
Know when to pause
- Hole size, concrete condition or drilling method differs from the released system.
- Adhesive condition, mixing, temperature or working/cure limit is outside the product criteria.
- A bar moves during cure or impalement guarding and installation records are lost.
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
- Which design and adhesive instructions apply to this bar, hole method and concrete condition?
- How will installers control dust during the permitted cleaning process and chemical exposure during dispensing?
- Who records substrate temperature, installation time, cure restrictions and the subsequent loading release?
Training and qualifications to confirm
- Instruction and any required qualification for the selected adhesive rebar system, cleaning accessories, dispensing and cure limits.
- Hazard-communication and exposure-control instruction for the adhesive, hole-cleaning dust and protruding bar protection.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Can any cleaned hole accept any rebar adhesive?
No. Hole formation, dimensions, base condition, bar and cleaning method must match the design and selected system. This example begins with released drilled holes but still requires installation-condition acceptance.
What must the crew record for actual use?
Record the design revision, hole and bar identification, product/lot and expiration, approved preparation method, actual substrate conditions and installation times, embedment findings, cure restrictions, inspection actions and loading release.

Task-by-task control and verification rationale
1. Accept the connection design
Hazard: Wrong bars, embedment or an unsuitable base material can create a fastening that later fails under load.
Control: Installation lead compares the released bar and hole schedule with the actual concrete and approved adhesive system. Obtain the required inspection arrangements; hold undocumented holes or conditions outside the design and product approval.
Verification: Lead checks hole identification, schedule and supporting release before preparation.
Why this belongs in the analysis: A structural adhesive connection needs more than a convenient drilled hole.
2. Prepare the installation station
Hazard: Adhesive contact, splash or unexpected movement of long bars can injure nearby workers.
Control: Arrange labeled products, current SDS, washing supplies and specified hand and eye protection. Support the bars, separate the work from passersby and establish a controlled dispensing/waste area with product-required ventilation.
Verification: Foreperson checks chemical controls and bar-handling space before packs are opened.
Why this belongs in the analysis: Exposure control and bar support must exist before dispensing begins.
3. Verify and clean receiving holes
Hazard: Dust or unsuitable hole condition can impair bonding; cleaning can expose the crew to airborne silica.
Control: Installer verifies the specified hole dimensions and condition, then uses the actual system’s approved cleaning tools and method. Assess silica exposure for that method; do not substitute a quick air blast or assume vacuuming alone satisfies the product instructions.
Verification: Installer records the accepted hole condition and cleaning method for the installation review.
Why this belongs in the analysis: Both bond reliability and worker exposure depend on how cleaning is performed.
4. Prepare and dispense adhesive
Hazard: Expired material, incorrect mixing or chemical leakage can harm people and leave an unreliable connection.
Control: Check product identity, storage condition, expiration, dispenser and mixing nozzle against instructions. Follow the specified initial discard and filling method while controlling splash and waste; stop for damage or inconsistent material.
Verification: Installer verifies pack identity and dispensing readiness before filling each released hole.
Why this belongs in the analysis: A full-looking hole does not establish a correctly mixed adhesive system.
5. Insert bars and protect the cure
Hazard: A displaced bar or early load can disturb the adhesive; exposed ends can create impalement exposure.
Control: Mark the specified embedment and install bars by the approved method within actual working limits. Maintain required bar support and movement restrictions throughout the product-specific cure; guard fall-onto protruding steel exposures.
Verification: Installer records bar position, substrate conditions and installation times; lead checks protection.
Why this belongs in the analysis: Cure limits come from the selected system and conditions, not a universal waiting time.
6. Record and hand over restrictions
Hazard: Another crew can use an unaccepted dowel as a handle or load an incompletely cured connection.
Control: Mark unreleased connections and transfer installation records, cure restrictions and unresolved findings to the responsible reviewer. Loading or further connection work proceeds only after its required acceptance and release; dispose of waste under product and site arrangements.
Verification: Lead confirms the receiving crew understands the marked restrictions and outstanding review.
Why this belongs in the analysis: Installation completion and permission to load are separate decisions.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Blow out the hole and epoxy the bar. | Installer uses the selected system’s approved cleaning method with assessed silica controls, then records hole acceptance and installation conditions. |
| Wait until the epoxy looks hard. | Installer records actual substrate conditions and installation times; the responsible reviewer applies the system-specific cure and loading criteria before release. |
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.
