• B. Never; it's a one-time document
• C. Only during initial planning
• D. After changes to the job or after incidents.

Answer: (D)

A Job Hazard Analysis should be updated whenever the job changes or after incidents to keep the analysis aligned with how the work is actually performed. When tools, materials, equipment, procedures, or the work environment change, the risks can shift, and the existing controls may no longer be adequate. Updating the JHA in those moments ensures that new hazards are identified and new or adjusted safeguards are put in place before they cause harm. Similarly, after an incident or near-miss, reviewing and revising the JHA helps address what failed and prevents recurrence by updating controls or procedures accordingly. This approach treats safety analysis as a living document that evolves with the job, rather than a one-off or externally driven task. Relying on inspectors, keeping it only for initial planning, or never updating would leave gaps where new hazards could go unmanaged.
