A JSA should be updated when what occurs?

• A. Only when the task is new.
• B. Only after a serious incident.
• C. On a regular annual basis, regardless of changes.
• D. Whenever the task or conditions change, the JSA should be updated.

Answer: (D)

A Job Safety Analysis should be updated whenever the task or the conditions under which it’s performed change. The purpose of a JSA is to identify hazards and define controls that match how the work is actually done. When you swap out equipment, change the workflow, alter the workspace layout, face different weather or lighting, introduce new materials or processes, or bring in new workers, the hazards and the effectiveness of existing controls can shift. Updating makes sure the steps, hazards, and controls stay accurate, keeps workers informed, and helps prevent injuries by reflecting current realities. It also lets you capture lessons from near-misses or incidents and incorporate crew feedback.

Relying only on updating when the task is new misses evolving risks; updating after a serious incident is reactive rather than preventive; and updating on a fixed annual schedule regardless of changes can leave newer hazards unaddressed.
