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 Rebar Installation JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
01Prepare the laydown and work area
Possible hazards: Unstable ground, obstructed routes, exposed bar ends, or nearby equipment can cause trips, impalement, or struck-by injuries.
Planned controls: The supervisor separates the laydown area from pedestrian travel, identifies sound support for stored steel, and establishes protected access to the placement area. Guard protruding reinforcement before adjacent work exposes people to a fall onto it. Resolve overhead electrical and excavation interfaces before delivery equipment enters.
Check before work: Walk the delivery and pedestrian routes and identify which protruding bars require impalement protection.
02Unload and stabilize bundles
Possible hazards: A bundle can roll or shift when landed or unbanded; suspended or elevated steel can crush nearby workers.
Planned controls: Use equipment and attachments suitable for the bundle's weight and shape. Keep workers outside the load path and place the steel onto prepared supports that prevent rolling. Release restraints only after stability is established. If cranes and rigging are used, apply the separate lift arrangements and required qualified roles.
Check before work: Confirm weight, equipment capacity, support spacing, exclusion area, and the method for safely removing banding.
03Move bars to the installation position
Possible hazards: Long bars can strike coworkers, contact obstructions, or strain workers during lifting, turning, and carrying.
Planned controls: Mechanically move material near the point of use. For remaining manual transfers, select a manageable load and enough assistance, agree movement commands, and keep the path clear. Carry and turn as a coordinated team without trapping hands between bars and fixed objects. Set steel down onto prepared supports.
Check before work: Confirm the bar ends clear obstructions and that the crew has a planned set-down point before lifting.
04Cut or bend scheduled bars at the work station
Possible hazards: Moving blades or bending pins can crush hands; abrasive cutting can eject fragments and sparks.
Planned controls: Use the specified guarded cutter or bender, support the bar, and keep hands outside the machine's danger area. Permit only trained operators. Stop and isolate equipment before adjustment or clearing a jam. If an abrasive method is introduced, assess wheel compatibility, guarding, sparks, fire exposure, noise, and required eye and face protection separately.
Check before work: Verify the tool, guards, emergency stop or stopping control, material supports, and exclusion of bystanders.
05Place bars and establish support
Possible hazards: Bars can shift underfoot; unsupported reinforcement can overturn, and workers can fall onto exposed starters.
Planned controls: Install supports and ties in the specified sequence while preserving stable walkways. Do not climb or use an incomplete mat as an improvised platform. Maintain impalement guarding as bars are added. Any change to walls, columns, or freestanding cages needs adequate support against overturning and collapse under 1926.703(d)(1).
Check before work: Verify the current work area is stable and protected before the next bars are brought into it.
06Tie reinforcement and manage repeated work
Possible hazards: Repeated stooping and forceful wrist movement can strain workers; tie-wire ends can puncture hands and eyes.
Planned controls: Use suitable powered or extended-handle tying tools where compatible with the work, arrange material within comfortable reach, and vary duties to reduce prolonged awkward postures. Maintain tool guards and keep hands clear of the tying mechanism. Use appropriate hand and eye protection and turn wire ends away from contact areas.
Check before work: Observe several actual ties: can workers reach the location without sustained bending or excessive force?
07Clear scraps and hand over the reinforcement
Possible hazards: Loose wire, offcuts, missing guards, and changed access can expose the next trade to trips and impalement.
Planned controls: Collect wire and offcuts into suitable containers, stabilize remaining stock, and restore displaced protection. Identify incomplete areas and keep them restricted. Hand over placement restrictions and guard locations to the formwork and concrete crews; arrange the required reinforcement inspection separately from this task analysis.
Check before work: Confirm the access route, guards, and unfinished work status with the receiving crew.
Example scope and starting conditions
This fictional example follows a reinforcement crew installing a slab-on-grade mat with short vertical starter bars. Bundles are delivered to a designated laydown area, mechanically moved close to use, and distributed into position before tying. It does not cover elevated bridge decks, freestanding cages, post-tensioning, or workers climbing vertical reinforcement. Those changes require additional structural, lifting, and fall-protection planning. Its sequence separates handling and tying work from structural, lifting, and fall-protection approvals.
- Obtain the bar schedule and actual bundle weights; identify where delivery equipment, pedestrians, and other trades may cross.
- Check the ground and proposed storage supports, nearby electrical lines, excavations, and openings. Define routes across the mat without relying on walking loosely supported bars.
- Identify protruding bars onto which a worker could fall. Select a guarding system capable of preventing impalement for the actual exposure, rather than choosing a cap by appearance.
- Identify the mechanical handling method, authorized operator, rigging responsibilities where applicable, and a suitable cutting and bending station.
Know when to pause
- Reassess for an elevated deck, vertical cage, crane pick, overhead electrical line, or a different delivery attachment.
- Pause for rolling bundles, unstable mat supports, missing impalement guards, or unplanned cutting and welding.
- Review the handling method when bar length, bundle weight, crew size, or repetition increases.
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.
Decisions that change the plan
Every starter has an orange cap. Is the impalement hazard resolved?
Only if the guarding is suitable for preventing impalement under the actual conditions. A small visibility or scratch-protection cap should not be assumed to stop a falling worker.
The crew starts assembling a tall cage using this slab-mat example. What changes?
The cage's temporary stability, lifting points, erection sequence, access, and fall exposure need a separate assessment and support design as appropriate before assembly proceeds.

Task-by-task control and verification rationale
Prepare the laydown and work area
Hazard: Unstable ground, obstructed routes, exposed bar ends, or nearby equipment can cause trips, impalement, or struck-by injuries.
Control: The supervisor separates the laydown area from pedestrian travel, identifies sound support for stored steel, and establishes protected access to the placement area. Guard protruding reinforcement before adjacent work exposes people to a fall onto it. Resolve overhead electrical and excavation interfaces before delivery equipment enters.
Verification: Walk the delivery and pedestrian routes and identify which protruding bars require impalement protection.
Why this belongs in the analysis: Hazard identification should follow where people move and could fall, not simply count visible bar ends.
Unload and stabilize bundles
Hazard: A bundle can roll or shift when landed or unbanded; suspended or elevated steel can crush nearby workers.
Control: Use equipment and attachments suitable for the bundle's weight and shape. Keep workers outside the load path and place the steel onto prepared supports that prevent rolling. Release restraints only after stability is established. If cranes and rigging are used, apply the separate lift arrangements and required qualified roles.
Verification: Confirm weight, equipment capacity, support spacing, exclusion area, and the method for safely removing banding.
Why this belongs in the analysis: A bundle's stability can change the moment a strap or sling is released.
Move bars to the installation position
Hazard: Long bars can strike coworkers, contact obstructions, or strain workers during lifting, turning, and carrying.
Control: Mechanically move material near the point of use. For remaining manual transfers, select a manageable load and enough assistance, agree movement commands, and keep the path clear. Carry and turn as a coordinated team without trapping hands between bars and fixed objects. Set steel down onto prepared supports.
Verification: Confirm the bar ends clear obstructions and that the crew has a planned set-down point before lifting.
Why this belongs in the analysis: Bar length, balance, repetition, and available space matter as well as its weight.
Cut or bend scheduled bars at the work station
Hazard: Moving blades or bending pins can crush hands; abrasive cutting can eject fragments and sparks.
Control: Use the specified guarded cutter or bender, support the bar, and keep hands outside the machine's danger area. Permit only trained operators. Stop and isolate equipment before adjustment or clearing a jam. If an abrasive method is introduced, assess wheel compatibility, guarding, sparks, fire exposure, noise, and required eye and face protection separately.
Verification: Verify the tool, guards, emergency stop or stopping control, material supports, and exclusion of bystanders.
Why this belongs in the analysis: Gloves address sharp surfaces; they do not prevent a cutter or bender from crushing a hand.
Place bars and establish support
Hazard: Bars can shift underfoot; unsupported reinforcement can overturn, and workers can fall onto exposed starters.
Control: Install supports and ties in the specified sequence while preserving stable walkways. Do not climb or use an incomplete mat as an improvised platform. Maintain impalement guarding as bars are added. Any change to walls, columns, or freestanding cages needs adequate support against overturning and collapse under 1926.703(d)(1).
Verification: Verify the current work area is stable and protected before the next bars are brought into it.
Why this belongs in the analysis: The finished structural arrangement does not establish the stability of every temporary installation stage.
Tie reinforcement and manage repeated work
Hazard: Repeated stooping and forceful wrist movement can strain workers; tie-wire ends can puncture hands and eyes.
Control: Use suitable powered or extended-handle tying tools where compatible with the work, arrange material within comfortable reach, and vary duties to reduce prolonged awkward postures. Maintain tool guards and keep hands clear of the tying mechanism. Use appropriate hand and eye protection and turn wire ends away from contact areas.
Verification: Observe several actual ties: can workers reach the location without sustained bending or excessive force?
Why this belongs in the analysis: An ergonomic control should change the effort or posture of the task, rather than only remind people to lift correctly.
Clear scraps and hand over the reinforcement
Hazard: Loose wire, offcuts, missing guards, and changed access can expose the next trade to trips and impalement.
Control: Collect wire and offcuts into suitable containers, stabilize remaining stock, and restore displaced protection. Identify incomplete areas and keep them restricted. Hand over placement restrictions and guard locations to the formwork and concrete crews; arrange the required reinforcement inspection separately from this task analysis.
Verification: Confirm the access route, guards, and unfinished work status with the receiving crew.
Why this belongs in the analysis: Protection must survive the handover; a tidy completed row is not evidence that the site remains controlled.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Put caps on all rebar. | Identify where a person could fall onto projecting steel and install a guarding system that prevents impalement for that exposure. |
| Back strain: lift properly. | Deliver bars near use, use mechanical movement and supported staging, and select tools that reduce repeated bending during tying. |
Common questions
Does this rebar JHA include post-tensioning?
No. Tensioning introduces stored-energy and exclusion-area requirements beyond ordinary reinforcing-bar placement.
Is fall protection triggered only within six feet of an edge?
No. Do not confuse horizontal distance from an edge with fall height. Apply the correct requirement to the walking surface, formwork face, reinforcement, or access equipment actually used.
