You know the work. Let’s turn that experience into a plan your crew can talk through. Start with today’s job, then check the steps together.
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 Scaffold JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
01Confirm the design and sequence
Possible hazards: An unsuitable configuration or improvised sequence leaves the scaffold unstable or exposes the erection crew to a fall.
Planned controls: Have the qualified designer establish the configuration and loading. The competent erection lead reviews the sequence, access, and fall protection for each incomplete stage, including feasible protection that does not create a greater hazard.
Check before work: Identify design and method references; confirm roles, selected crew, protection equipment, and any unresolved design questions.
02Prepare the foundation and exclusion area
Possible hazards: A base settles or slides; a passing person is struck by a frame or falling component.
Planned controls: Verify the foundation can support the scaffold loads without settlement. Install specified base plates, sills, or other adequate support. Divert pedestrians and establish controlled laydown and lifting/lowering zones.
Check before work: The erection lead examines ground/support information and checks that barriers prevent people from entering the handling area.
03Inspect and erect the lower stages
Possible hazards: Damaged components, missing braces, or incompatible connections allow collapse; handling frames injures hands or backs.
Planned controls: Reject defective components and use the designed system. Assemble base frames, connections, bracing, and platforms in the approved sequence. Use planned handling aids and coordinated movements; keep hands clear of seating connections.
Check before work: The competent person checks foundation contact, plumb, connections, and initial bracing before height is increased.
04Add levels, access, ties, and edge protection
Possible hazards: Workers fall from incomplete levels; unsecured sections overturn; dropped components strike people below.
Planned controls: Install ties and bracing as erection progresses in accordance with the design. Provide planned access and required protection at each stage. Do not climb cross braces. Maintain the drop zone and use controlled material transfer.
Check before work: The erection lead verifies tie locations, safe access, anchorage/protection arrangements, and the next stage before the crew advances.
05Inspect and hand over for use
Possible hazards: Other trades enter an incomplete or overloaded scaffold, remove a brace, or create a falling-object exposure.
Planned controls: A competent person inspects before use, before each work shift, and after events that could affect structural integrity. Communicate permitted loads, access, limitations, and alteration control to users; maintain appropriate falling-object protection.
Check before work: Record actual findings and restrictions and correct defects before use. Train users to recognize hazards and report changes.
06Dismantle and clear the work area
Possible hazards: Premature removal of ties, bracing, platforms, or access destabilizes remaining sections or leaves workers exposed.
Planned controls: The competent erection/dismantling lead directs the planned removal sequence. Retain necessary stability, access, and fall protection for each remaining stage. Lower components in a controlled manner; do not throw them or allow unauthorized entry.
Check before work: Confirm each section is ready for removal; segregate damaged components and inspect the area before removing barriers.
Example scope and starting conditions
Fictional example: a specialist crew erects and later dismantles a stationary, supported fabricated-frame scaffold beside a low-rise building for exterior repairs. The scaffold has several working levels, a specified access arrangement, and a nearby pedestrian route. Its exact dimensions, loading, ties, foundation, and fall-protection provisions must come from the project design. This example excludes suspended scaffolds, mobile towers, and mast climbers and does not supply scaffold engineering or an erection method.
- A qualified person designs the scaffold. A competent person qualified in erection and dismantling directs trained, experienced employees selected for that work.
- Identify the scaffold system, compatible components, intended workforce/material loading, design reference, manufacturer instructions, and the condition of the supporting surface.
- Plan the pedestrian diversion, material-lowering zone, overhead/electrical interfaces, access during each stage, fall protection, and rescue arrangements before components arrive.
- Determine applicable federal, state, contract, and manufacturer requirements. A color tag communicates status but cannot establish structural adequacy or replace inspection.
Know when to pause
- Stop for foundation movement, impact, missing ties, unauthorized changes, component damage, or a loading change.
- Reassess weather, sheeting or netting, nearby cranes, electrical exposures, and any request to move the scaffold.
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
A brace blocks the repair area. Can the user remove it?
Stop that activity and refer the change to the responsible scaffold personnel and designer as necessary. Resolve an adequate configuration before alteration.
Wind screening is proposed after handover. What changes?
Screening can add wind loads. Review the design and anchorage implications and obtain the necessary revised instructions before installation.

Task-by-task control and verification rationale
Confirm the design and sequence
Hazard: An unsuitable configuration or improvised sequence leaves the scaffold unstable or exposes the erection crew to a fall.
Control: Have the qualified designer establish the configuration and loading. The competent erection lead reviews the sequence, access, and fall protection for each incomplete stage, including feasible protection that does not create a greater hazard.
Verification: Identify design and method references; confirm roles, selected crew, protection equipment, and any unresolved design questions.
Why this belongs in the analysis: A completed scaffold and a partly built scaffold present different stability and access problems.
Prepare the foundation and exclusion area
Hazard: A base settles or slides; a passing person is struck by a frame or falling component.
Control: Verify the foundation can support the scaffold loads without settlement. Install specified base plates, sills, or other adequate support. Divert pedestrians and establish controlled laydown and lifting/lowering zones.
Verification: The erection lead examines ground/support information and checks that barriers prevent people from entering the handling area.
Why this belongs in the analysis: Level appearance alone does not establish the capacity of a slab, fill, or underground structure.
Inspect and erect the lower stages
Hazard: Damaged components, missing braces, or incompatible connections allow collapse; handling frames injures hands or backs.
Control: Reject defective components and use the designed system. Assemble base frames, connections, bracing, and platforms in the approved sequence. Use planned handling aids and coordinated movements; keep hands clear of seating connections.
Verification: The competent person checks foundation contact, plumb, connections, and initial bracing before height is increased.
Why this belongs in the analysis: Early alignment and connection errors can propagate into every higher stage.
Add levels, access, ties, and edge protection
Hazard: Workers fall from incomplete levels; unsecured sections overturn; dropped components strike people below.
Control: Install ties and bracing as erection progresses in accordance with the design. Provide planned access and required protection at each stage. Do not climb cross braces. Maintain the drop zone and use controlled material transfer.
Verification: The erection lead verifies tie locations, safe access, anchorage/protection arrangements, and the next stage before the crew advances.
Why this belongs in the analysis: Calling a crew experienced does not remove the need to resolve its exposure while installing protective systems.
Inspect and hand over for use
Hazard: Other trades enter an incomplete or overloaded scaffold, remove a brace, or create a falling-object exposure.
Control: A competent person inspects before use, before each work shift, and after events that could affect structural integrity. Communicate permitted loads, access, limitations, and alteration control to users; maintain appropriate falling-object protection.
Verification: Record actual findings and restrictions and correct defects before use. Train users to recognize hazards and report changes.
Why this belongs in the analysis: A handover explains what the scaffold may support and what users must not change.
Dismantle and clear the work area
Hazard: Premature removal of ties, bracing, platforms, or access destabilizes remaining sections or leaves workers exposed.
Control: The competent erection/dismantling lead directs the planned removal sequence. Retain necessary stability, access, and fall protection for each remaining stage. Lower components in a controlled manner; do not throw them or allow unauthorized entry.
Verification: Confirm each section is ready for removal; segregate damaged components and inspect the area before removing barriers.
Why this belongs in the analysis: Dismantling needs its own staged decisions because the available protections progressively disappear.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Falls: tie off if needed. | Before each erection stage, resolve feasible safe fall protection, access, suitable attachment, and rescue under the competent person’s direction. |
| Scaffold is green-tagged. | Record the competent-person inspection and limitations; confirm actual conditions still match the inspected configuration. |
Common questions
Are scaffold erectors automatically exempt from fall protection?
No. Under 1926.451(g)(2), a competent person must determine feasibility and safety for supported-scaffold erection/dismantling. Provide protection where installation and use are feasible and do not create a greater hazard; a blanket exemption is inappropriate.
Who designs, directs, and inspects the scaffold?
The qualified person designs it. A competent person qualified in the activity supervises erection, movement, alteration, or dismantling. Competent-person inspections address visible defects. One person may fill multiple roles only when meeting each role’s requirements.
