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 Masonry Cell Reinforcement 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 wall and reinforcement detail
Possible hazards: A displaced starter, unsupported wall or wrong cell can leave an incomplete structural load path.
Planned controls: Masonry lead verifies the supported wall lift, cell map, starter arrangement and current reinforcement schedule. Confirm bars, splice locations and inspection hold points match the actual construction. Hold a starter misalignment or missing path for design disposition; do not bend bars or break a web to force a fit.
Check before work: Lead compares actual wall cells and starters with the released schedule before bar movement.
022. Prepare guarded access and bar staging
Possible hazards: Long bars can strike workers or impale someone falling onto a starter during elevated placement.
Planned controls: Establish accepted guarded work positions and protect exposed impalement hazards along the handling route. Stage manageable scheduled bars on stable supports within permitted platform loads. Agree lifting/lowering commands and a controlled bar-end path; keep other work outside the receiving and drop areas.
Check before work: Handling lead checks platform limits, starter protection and the complete bar-end travel route.
033. Verify the open cell and cleanout path
Possible hazards: Mortar debris or hidden obstruction can prevent proper seating and later grout enclosure of the bar.
Planned controls: Inspect the designated open cells and released cleanouts for alignment, obstructions and the design’s grout-space criteria. Arrange permitted cleaning with assessed dust controls and waste collection, preserving wall support. Keep cleanouts available for inspection; report inaccessible spaces instead of hiding them behind a bar or patch.
Check before work: Lead records actual cell-path and cleanliness findings before insertion.
044. Lower and connect the scheduled bars
Possible hazards: A released bar can drop, trap hands at the starter or land in the wrong cell.
Planned controls: Use the planned assistance or suitable handling aid to lower each identified bar under coordinated control from protected positions. Keep hands outside closing gaps and connect only the scheduled splice at its permitted location. Maintain control until the specified restraint is effective; use no generic lap length or improvised bar offset.
Check before work: Installation lead checks bar identity, cell location and the actual splice before release.
055. Position and restrain for inspection
Possible hazards: Misplaced or loose steel can shift during grouting and lose required clearance or structural function.
Planned controls: Install the design’s positioning and restraint arrangement, using safe tying/tool positions and controlling wire ends. Verify bar position, prescribed clearances and all splices against actual project criteria. Keep access and cleanouts open for the assigned pre-grout review; resolve obstructions without modifying the specified reinforcement.
Check before work: Designated reviewer records concealed-position, restraint and splice findings before closure.
066. Hand over the pre-grout condition
Possible hazards: Premature cleanout closure or pumping can conceal unchecked bars and overload an unaccepted wall stage.
Planned controls: Transfer actual cell, bar, splice and inspection records to the masonry/grouting leads, identifying all holds. Close cleanouts only through the approved method after required inspection, with closure acceptance under the grout plan. Preserve wall supports, starter protection and access restrictions; grout placement begins under its separate release.
Check before work: Receiving lead confirms inspection status and outstanding closure/grout-release conditions.
Example scope and starting conditions
A masonry reinforcement crew will place, splice and restrain specified vertical bars in the open cells of one already erected and temporarily supported low-rise CMU wall lift before separate grouting. Released cleanouts and guarded access allow inspection of the cell path and concealed bar positions. Scheduled bars arrive prepared; no units are laid during this operation. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Current masonry documents identify cells, bar marks, permitted splices, position/clearance criteria, restraints and required pre-grout inspections for the actual wall lift.
- The wall and access are independently accepted for installation; required cleanouts are open and visible, starter positions are released and planned bar handling avoids impalement exposure.
- Partial masonry-rebar and reinforced-wall coverage: vertical cell bars only; slab mats, freestanding cages, horizontal bond-beam steel, cutting/bending and grout pumping are excluded.
Know when to pause
- Cells, starters, scheduled bar marks or splice positions differ from the released masonry documents.
- Protected handling, impalement guarding, cell inspection or the specified restraint cannot be maintained.
- A request introduces bar bending, unit removal, horizontal steel, cleanout concealment before inspection or early grouting.
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 do the actual cells, starters and scheduled splices match the current masonry design?
- What prevents bars shifting or striking workers while they are lowered and connected?
- Which records verify concealed reinforcement and clean grout space before cleanouts are closed and grouting begins?
Training and qualifications to confirm
- The actual masonry reinforcement schedule, cell/starter identification, permitted splice and restraint requirements and pre-grout inspection sequence.
- Controlled long-bar handling from guarded access, impalement protection, safe tying positions and task-specific dust controls for any cell cleaning.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Does the generic slab rebar example cover these bars?
No. That crew distributes a mat over an open slab surface. Here the retained masonry cell path, starter splice, concealed position and pre-grout cleanout inspection govern placement. The general masonry-work row introduces reinforcement but does not complete this separate cell-installation sequence.
What must the crew record for actual use?
Record the actual work boundary, equipment and materials, responsible people, applicable criteria, control checks and unresolved actions. Keep changed conditions on hold, communicate restrictions to affected crews and obtain the required project authorization before work.

Task-by-task control and verification rationale
1. Accept the wall and reinforcement detail
Hazard: A displaced starter, unsupported wall or wrong cell can leave an incomplete structural load path.
Control: Masonry lead verifies the supported wall lift, cell map, starter arrangement and current reinforcement schedule. Confirm bars, splice locations and inspection hold points match the actual construction. Hold a starter misalignment or missing path for design disposition; do not bend bars or break a web to force a fit.
Verification: Lead compares actual wall cells and starters with the released schedule before bar movement.
Why this belongs in the analysis: The surrounding masonry constrains where a bar can be placed and inspected.
2. Prepare guarded access and bar staging
Hazard: Long bars can strike workers or impale someone falling onto a starter during elevated placement.
Control: Establish accepted guarded work positions and protect exposed impalement hazards along the handling route. Stage manageable scheduled bars on stable supports within permitted platform loads. Agree lifting/lowering commands and a controlled bar-end path; keep other work outside the receiving and drop areas.
Verification: Handling lead checks platform limits, starter protection and the complete bar-end travel route.
Why this belongs in the analysis: A clear walking route may still be too confined for turning a long bar.
3. Verify the open cell and cleanout path
Hazard: Mortar debris or hidden obstruction can prevent proper seating and later grout enclosure of the bar.
Control: Inspect the designated open cells and released cleanouts for alignment, obstructions and the design’s grout-space criteria. Arrange permitted cleaning with assessed dust controls and waste collection, preserving wall support. Keep cleanouts available for inspection; report inaccessible spaces instead of hiding them behind a bar or patch.
Verification: Lead records actual cell-path and cleanliness findings before insertion.
Why this belongs in the analysis: Bar insertion can conceal defects in the space that must later receive grout.
4. Lower and connect the scheduled bars
Hazard: A released bar can drop, trap hands at the starter or land in the wrong cell.
Control: Use the planned assistance or suitable handling aid to lower each identified bar under coordinated control from protected positions. Keep hands outside closing gaps and connect only the scheduled splice at its permitted location. Maintain control until the specified restraint is effective; use no generic lap length or improvised bar offset.
Verification: Installation lead checks bar identity, cell location and the actual splice before release.
Why this belongs in the analysis: A visible bar projecting from the wall does not reveal its lower splice or correct cell.
5. Position and restrain for inspection
Hazard: Misplaced or loose steel can shift during grouting and lose required clearance or structural function.
Control: Install the design’s positioning and restraint arrangement, using safe tying/tool positions and controlling wire ends. Verify bar position, prescribed clearances and all splices against actual project criteria. Keep access and cleanouts open for the assigned pre-grout review; resolve obstructions without modifying the specified reinforcement.
Verification: Designated reviewer records concealed-position, restraint and splice findings before closure.
Why this belongs in the analysis: The arrangement must hold its required position through the later grout operation.
6. Hand over the pre-grout condition
Hazard: Premature cleanout closure or pumping can conceal unchecked bars and overload an unaccepted wall stage.
Control: Transfer actual cell, bar, splice and inspection records to the masonry/grouting leads, identifying all holds. Close cleanouts only through the approved method after required inspection, with closure acceptance under the grout plan. Preserve wall supports, starter protection and access restrictions; grout placement begins under its separate release.
Verification: Receiving lead confirms inspection status and outstanding closure/grout-release conditions.
Why this belongs in the analysis: Reinforcement completion is one prerequisite, not permission to start pumping.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Drop each bar into a nearby open cell. | Match the cell and bar schedule, control the lowering path and verify the specified starter splice and restraint before releasing the bar. |
| The wall is reinforced because steel projects above it. | Record actual bar positions, splices, restraint and grout-space findings through open cleanouts before the designated inspection and closure handover. |
Common questions
Can this example be used as a JSA?
Adapt the Task | Hazard | Control sequence to the employer’s JSA format and actual worksite. Name the people who will check controls and record their findings; this learning example supplies no completed field inspection.
What changes if the project requires an AHA?
Use the governing AHA format, risk method, supporting records and acceptance process. The published formwork AHA illustrates that additional structure. Add the actual competencies, inspections and project reviews rather than assuming a renamed JHA meets those requirements.
