(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:

• Surfaces hazards that would otherwise go unrecognized because familiarity with a routine task causes both workers and supervisors to stop consciously noticing its hazards ("normalization" of risk).
• Produces a concrete training and reference document that new or transferred workers can be trained against directly, standardizing how the job is done safely rather than relying on informal, worker-to-worker knowledge transfer.
• Prioritizes which jobs need attention first — JSAs are typically prioritized by injury history, severity potential, and frequency, so limited safety resources go to the highest-risk tasks first.
• Provides a baseline for evaluating a proposed process/equipment change — comparing the JSA before and after a change quickly shows whether the change introduced a new hazard.
• Improves the underlying job, not just its safety — breaking a job into explicit steps frequently reveals inefficiencies or quality problems alongside hazards, since a hazardous step and an error-prone step are often the same step.
• Engages the workers who perform the job, improving both the analysis (they know the real steps, including informal workarounds) and their buy-in to following the resulting procedure.

(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).

(iii) Basic Steps of an Effective Training Plan to Ensure Operators Follow the JSA's Operating Procedures

• Establish a clear, written procedure derived directly from the JSA — the training content should be the actual, step-by-step safe procedure the JSA produced, not a generic safety talk, so there is no gap between what is taught and what is required.
• Explain the "why," not only the "what" — train operators on the hazard each step's control addresses, not merely the mechanical action to take, since understanding the reason for a control step measurably improves compliance when the exact situation trained for doesn't recur identically.
• Combine explanation, demonstration, and supervised practice — tell the operator the procedure, show it being performed correctly, then have the operator perform it under observation before working unsupervised, rather than relying on a one-way lecture or a document to read alone.
• Verify competency before sign-off — confirm through direct observation (not just a signed acknowledgement) that the operator can actually perform the procedure correctly, and document that verification.
• Reinforce through job observation and feedback — periodic supervisor observation of the job as actually performed, with immediate, specific feedback when a deviation is seen, closes the gap between what was trained and what happens day-to-day under production pressure.
• Retrain on any change or after an incident — whenever the JSA is updated (step 6 of part ii), or following any incident/near-miss involving the job, retrain every affected operator on the revised procedure rather than assuming the original training still applies.
• Track completion and schedule periodic refreshers — maintain training records and require refresher training at a defined interval, since compliance with an infrequently reinforced procedure tends to drift over time even without any formal change to the procedure itself.
