(i) What a Job Safety Analysis Is, and Its Benefits

A job safety analysis (JSA) — also called a job hazard analysis (JHA) — is a structured technique that breaks a specific job down into its sequential basic steps, identifies the hazard(s) present at each step, and specifies the safe procedure or control that eliminates or reduces each identified hazard. It is a task-level counterpart to the design-level techniques of Question 4(iii): where PHA/FMEA/FTA analyze a system or component, a JSA analyzes the job as the worker actually performs it.

Benefits of completing a JSA:

(ii) Stages of a Job Safety Analysis

  1. Select the job to analyze. Prioritize using injury/incident frequency and severity, the potential for severe consequences even if the injury rate is currently low, jobs that are new or have recently changed, and jobs performed infrequently enough that workers have less practiced familiarity.
  2. Break the job into its basic sequential steps. Observe (or have an experienced worker describe) the job in the order it is actually performed, recording each distinct step — not so finely broken down that the analysis becomes unwieldy, and not so coarsely that a step hides a hazard within it.
  3. Identify the hazard(s) present at each step. For every step, systematically ask what could go wrong — can the worker be struck by, caught in/between, exposed to, overexert on, or lose control of something — and record every credible hazard, not only the most obvious one.
  4. Determine the recommended safe procedure/control for each identified hazard. Apply the hierarchy of controls to each hazard identified in step 3, specifying an actionable, step-specific control (not a generic caution), and involve the workers who perform the job in developing it.
  5. Document, communicate, and train. Record the completed JSA in a standard format, communicate it to every worker who performs the job (feeding directly into part iii), and post or make it readily accessible at the point of work.
  6. Review and update periodically. Re-review the JSA whenever the job, equipment, or materials change, after any incident/near-miss involving the job, and on a defined periodic schedule regardless — the same monitor-and-review principle established in Question 2(i).
