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 Cementitious Baseplate Grouting JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Confirm support and the grout release
Possible hazards: Disturbing support or changing a connection can cause movement of the supported member.
Planned controls: Foreperson confirms the erection support remains effective and identifies the grouting limits. No bolts, shims or bracing are altered without the required design release.
Check before work: Compare the actual support and baseplate condition with the current erection and grouting instructions.
022. Prepare the base and containment
Possible hazards: Loose debris, sharp edges and dusty preparation can injure the crew or obstruct the pour.
Planned controls: Use the specified preparation method with assessed dust controls. Install forms and route access so workers can place grout without reaching into a pinch zone.
Check before work: Lead checks the prepared surface and form stability before materials are mixed.
033. Inspect the mixer and stage bags
Possible hazards: Moving mixer parts, heavy bags and cement dust can cause injury.
Planned controls: Use guarded equipment in suitable condition, handle bags with assistance or equipment and stage them near the feed point without blocking access. Follow the applicable silica-control assessment and product handling instructions.
Check before work: Operator checks guards and controls; lead checks the feed route and dust-control arrangements.
044. Mix the specified batch
Possible hazards: Cement splash can burn skin and eyes; reaching into moving equipment can cause entanglement.
Planned controls: Charge and mix in the product sequence with selected cement protection. Keep hands and tools outside moving parts and stop and secure energy before clearing the mixer.
Check before work: Operator confirms water and batch settings against instructions and checks splash containment.
055. Place grout without disturbing support
Possible hazards: Wet grout can contact skin; rushed placement can force workers into awkward or trapped positions.
Planned controls: Place from the planned access using suitable containers and tools. Maintain support and containment, prevent contact and hold the work if form leakage or member movement appears.
Check before work: Lead monitors forms and member condition while the crew places grout.
066. Clean and maintain the cure restriction
Possible hazards: Wet residues can cause slips and burns; early loading can compromise the planned support.
Planned controls: Clean by the specified wet method, collect residues and mark the cure restriction. Keep load and support decisions with the designated authority and communicate them at handover.
Check before work: Foreperson checks cleanup and records the required loading release and responsible authority.
Example scope and starting conditions
A small crew will mix and place nonshrink cementitious grout beneath an installed steel baseplate on a ground-level foundation. The supported member remains stabilized under the erection plan. This fictional learning example records planned controls; it supplies no actual inspections or work authorization.
- The connection design and product specification provide the grout, preparation and load-release requirements.
- Forms, clearances and access can be prepared without disturbing the member’s temporary support.
- This excludes epoxy grout, pumped masonry grout, pressure injection and release of structural bracing.
Know when to pause
- Support moves or anyone proposes adjusting bolts, shims or braces.
- Product, preparation or mix method changes.
- Leakage, dust-control failure or an unclear loading release occurs.
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 keeps the member stable while the grout is placed and cures?
- Which preparation and mix instructions apply to this product?
- Who can release loading or remove temporary support after cure?
Training and qualifications to confirm
- Mixer guarding and shutdown, cement protection and applicable silica instruction.
- Recognizing the support and load-release boundary.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
May the crew remove bracing when the grout appears hard?
No. Appearance alone is not the specified strength or connection release. Use the project’s documented cure, testing and support-release criteria with the designated authority.
What must be recorded before this example is used on a job?
Replace the scenario with the actual work, identify additional hazards with the crew, and record the applicable instructions, responsible people, inspection findings, unresolved actions and required authorization. A planned verification is not an inspection result.

Task-by-task control and verification rationale
1. Confirm support and the grout release
Hazard: Disturbing support or changing a connection can cause movement of the supported member.
Control: Foreperson confirms the erection support remains effective and identifies the grouting limits. No bolts, shims or bracing are altered without the required design release.
Verification: Compare the actual support and baseplate condition with the current erection and grouting instructions.
Why this belongs in the analysis: Grout placement does not authorize changing structural support.
2. Prepare the base and containment
Hazard: Loose debris, sharp edges and dusty preparation can injure the crew or obstruct the pour.
Control: Use the specified preparation method with assessed dust controls. Install forms and route access so workers can place grout without reaching into a pinch zone.
Verification: Lead checks the prepared surface and form stability before materials are mixed.
Why this belongs in the analysis: Preparation must preserve the supported member’s stability.
3. Inspect the mixer and stage bags
Hazard: Moving mixer parts, heavy bags and cement dust can cause injury.
Control: Use guarded equipment in suitable condition, handle bags with assistance or equipment and stage them near the feed point without blocking access. Follow the applicable silica-control assessment and product handling instructions.
Verification: Operator checks guards and controls; lead checks the feed route and dust-control arrangements.
Why this belongs in the analysis: Bag handling and dry charging differ from wet placement.
4. Mix the specified batch
Hazard: Cement splash can burn skin and eyes; reaching into moving equipment can cause entanglement.
Control: Charge and mix in the product sequence with selected cement protection. Keep hands and tools outside moving parts and stop and secure energy before clearing the mixer.
Verification: Operator confirms water and batch settings against instructions and checks splash containment.
Why this belongs in the analysis: The product controls the mix; the JHA does not invent a ratio.
5. Place grout without disturbing support
Hazard: Wet grout can contact skin; rushed placement can force workers into awkward or trapped positions.
Control: Place from the planned access using suitable containers and tools. Maintain support and containment, prevent contact and hold the work if form leakage or member movement appears.
Verification: Lead monitors forms and member condition while the crew places grout.
Why this belongs in the analysis: A clear access method reduces both cement contact and structural interference.
6. Clean and maintain the cure restriction
Hazard: Wet residues can cause slips and burns; early loading can compromise the planned support.
Control: Clean by the specified wet method, collect residues and mark the cure restriction. Keep load and support decisions with the designated authority and communicate them at handover.
Verification: Foreperson checks cleanup and records the required loading release and responsible authority.
Why this belongs in the analysis: A filled baseplate is not evidence that strength criteria have been met.
