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.
Print your own JHA by signing in, or contribute the selected structured categories as a guest. Signing in does not require research participation. Written job details are processed to prepare your export and are stored on our server only if you save to your private company library.

Your entries stay in this working draft as you move between steps. Required field checks, employer review and work authorization remain separate.
Your Structural Steel Field Welding JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Release the connection and procedure
Possible hazards: Welding the wrong connection or disturbing required support can weaken the frame.
Planned controls: Erection and welding leads confirm current connection details, the applicable procedure and weld sequence. Verify stable access and retain required temporary restraint through the acceptance stage.
Check before work: Lead compares the work location and base material with released documents.
022. Control the hot-work area
Possible hazards: Sparks and radiation can injure other workers or ignite concealed materials.
Planned controls: Obtain the site hot-work authorization, remove or protect combustibles above, below and beyond the weld, and arrange required fire watch and extinguishing access. Use appropriate screens without defeating ventilation.
Check before work: Fire-watch lead checks adjacent spaces and the area beneath the platform.
033. Arrange electrical and fume controls
Possible hazards: Damaged leads or an unsuitable fume-control arrangement can cause shock or harmful exposure.
Planned controls: Inspect the welding circuit and provide the specified return connection without using prohibited structures as a return. Assess material and process fumes and arrange suitable extraction or ventilation and respiratory protection where required.
Check before work: Welding lead checks circuit condition and the selected exposure controls before energizing.
044. Make the weld
Possible hazards: Arc radiation, hot metal, fume and a poor working position can harm the welder.
Planned controls: Qualified welder follows the procedure from the protected position with assessed welding PPE. Keep cables clear of access, maintain fume controls and stop for loss of protection, unusual coating response or changed joint conditions.
Check before work: Welder and lead monitor work position and control performance during welding.
055. Inspect without releasing support
Possible hazards: Hot surfaces or premature structural release can injure inspecting or erection crews.
Planned controls: Mark hot metal, allow the specified cooling and obtain the required connection inspection. Retain support until the designated structural release; no teaching example supplies an accepted weld record.
Check before work: Inspector and erection lead record actual findings and unresolved defects.
066. Close hot work and hand over
Possible hazards: A concealed smoldering fire or abandoned energized lead can expose others.
Planned controls: Shut down and secure equipment, maintain fire-watch follow-up for the period required by the site authorization, and inspect affected spaces. Transfer weld and support status to the receiving crew.
Check before work: Hot-work lead records closeout and remaining restrictions.
Example scope and starting conditions
Qualified welders will make specified electric arc welds on released structural connections in a stabilized building frame from a protected work platform. The area below and behind the weld is controlled. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The welding procedure, base material, coating status and temporary support are identified before welding.
- The hot-work review addresses sparks, concealed combustibles, fume exposure, electrical supply and fire watch.
- This excludes oxy-fuel bracket fabrication, unknown coatings, confined-space welding and using weld completion alone to remove temporary support.
Know when to pause
- Unknown coating, changed joint detail or lost fume control.
- Fire watch, protected access or electrical protection fails.
- Frame movement or an unresolved weld defect affects support release.
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
- Which welding procedure and welder qualifications apply to these connections?
- What coatings or contaminants affect the fume-control method?
- Who verifies the fire area below and behind the work platform?
Training and qualifications to confirm
- Welder qualifications and demonstrated use of the actual welding procedure.
- Hot-work, fume, electrical and applicable steel-erection fall instruction for assigned roles.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Does the outdoor bracket welding example cover this connection?
It supplies general hot-work background. Field welding adds elevated access, structural procedure and qualifications, sparks to lower levels, connection inspection and temporary-support interfaces.
What must the crew record for actual use?
Identify the actual equipment and work boundaries, responsible people, applicable criteria, inspection findings and open actions. Resolve changes with affected crews and obtain required project authorization before work.

Task-by-task control and verification rationale
1. Release the connection and procedure
Hazard: Welding the wrong connection or disturbing required support can weaken the frame.
Control: Erection and welding leads confirm current connection details, the applicable procedure and weld sequence. Verify stable access and retain required temporary restraint through the acceptance stage.
Verification: Lead compares the work location and base material with released documents.
Why this belongs in the analysis: Welding starts with a structural and procedure release.
2. Control the hot-work area
Hazard: Sparks and radiation can injure other workers or ignite concealed materials.
Control: Obtain the site hot-work authorization, remove or protect combustibles above, below and beyond the weld, and arrange required fire watch and extinguishing access. Use appropriate screens without defeating ventilation.
Verification: Fire-watch lead checks adjacent spaces and the area beneath the platform.
Why this belongs in the analysis: Elevated sparks can travel beyond the welder’s immediate work area.
3. Arrange electrical and fume controls
Hazard: Damaged leads or an unsuitable fume-control arrangement can cause shock or harmful exposure.
Control: Inspect the welding circuit and provide the specified return connection without using prohibited structures as a return. Assess material and process fumes and arrange suitable extraction or ventilation and respiratory protection where required.
Verification: Welding lead checks circuit condition and the selected exposure controls before energizing.
Why this belongs in the analysis: Outdoor air or a respirator alone is not an exposure assessment.
4. Make the weld
Hazard: Arc radiation, hot metal, fume and a poor working position can harm the welder.
Control: Qualified welder follows the procedure from the protected position with assessed welding PPE. Keep cables clear of access, maintain fume controls and stop for loss of protection, unusual coating response or changed joint conditions.
Verification: Welder and lead monitor work position and control performance during welding.
Why this belongs in the analysis: Procedure quality and worker protection must remain active together.
5. Inspect without releasing support
Hazard: Hot surfaces or premature structural release can injure inspecting or erection crews.
Control: Mark hot metal, allow the specified cooling and obtain the required connection inspection. Retain support until the designated structural release; no teaching example supplies an accepted weld record.
Verification: Inspector and erection lead record actual findings and unresolved defects.
Why this belongs in the analysis: A visible finished bead is not acceptance of the connection.
6. Close hot work and hand over
Hazard: A concealed smoldering fire or abandoned energized lead can expose others.
Control: Shut down and secure equipment, maintain fire-watch follow-up for the period required by the site authorization, and inspect affected spaces. Transfer weld and support status to the receiving crew.
Verification: Hot-work lead records closeout and remaining restrictions.
Why this belongs in the analysis: Fire closeout and structural handover need separate evidence.

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.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
