Conducting a JHA Step by Step

Why This Matters

Conducting a JHA Step by Step deserves a specific pre-task check because tasks can appear routine while hidden steps, interfaces or abnormal conditions introduce serious hazards. For this briefing, connect the topic to the exact equipment, work area and conditions the crew will face today, and agree a clear stop-work trigger before the task begins.

Key Points

• List the task's basic steps in actual performance sequence, described at a level of specificity sufficient to identify distinct hazards per step
• For each step, systematically identify what could go wrong and the specific mechanism that would cause it
• Assign a defined control per identified hazard, applying elimination and engineering controls ahead of administrative controls and PPE per the hierarchy of controls

Best Practices

• Decompose the task into sequential steps before identifying hazards, rather than assessing the task as a single undifferentiated activity
• Involve the personnel who actually perform the task when developing or reviewing the JHA — their operational knowledge frequently surfaces hazards a desk review would miss
• Update the JHA whenever the task, tooling, materials, or surrounding conditions change materially
• Review the relevant JHA before performing an infrequent or unfamiliar task, not only for routine daily work
• Use the JHA to actively plan controls before task execution, not solely as a post-hoc documentation exercise
• Keep JHAs physically or digitally accessible at the point of task execution, not archived where they are rarely referenced

Scenario & Site Check

Discuss this scenario: A crew is about to start work where conducting a jha step by step is relevant, but one condition in the work area has changed since the task was last performed. Ask the team what could make that change important, which control must be verified first, and who has authority to stop the job.

• Field check: break one task into steps, identify what can go wrong at each step and confirm the control before proceeding.
• Evidence: confirm the applicable permit, inspection, label, test result, procedure or equipment status rather than relying only on memory.
• Close-out question: “What would make us stop and reassess this task today?”

Reference Point

Use the current requirement that applies to your site. A useful starting point for Job Hazard Analysis is OSHA / NIOSH primary guidance. Company procedures, manufacturer instructions and local law may impose additional or more stringent controls.
