    Job Safety AnalysisJSA

    Also known as: JHA, Job Hazard Analysis, Task Risk Assessment

    Definition

    Job Safety Analysis or Job Hazard Analysis — a task-based review of each work step, the hazards it involves and the controls chosen to manage them.

    Editorial definition: The QHSE Standard, updated 3 October 2026 · https://qhsetech.com/glossary/jsa

    Scope: Use the actual task and working conditions, and review the analysis when relevant circumstances change.

    Example for your evaluation: Show how a revised task is reviewed and communicated to the people doing the work.

    What OSHA and HSE say about analysing a job

    OSHA's booklet Job Hazard Analysis (OSHA 3071, 2002 revision) describes a job hazard analysis as a technique that focuses on job tasks as a way to identify hazards before they occur. It looks at the relationship between the worker, the task, the tools and the work environment. The booklet calls the analysis one component of the larger commitment of a safety and health management system, and says that for it to be effective management must follow through to correct the hazards it finds. 'Job safety analysis' and 'task risk assessment' are used for much the same exercise, and the glossary hub lists them as alternative names.

    The booklet's method is practical. It suggests involving employees, reviewing accident and near-miss history, doing a preliminary job review, listing and prioritising jobs by likelihood and severity, and then outlining the steps of the job by watching the work. Priority goes to jobs with the highest injury or illness rates, jobs that could cause severe or disabling injuries even without a history of accidents, jobs in which one simple human error could lead to a severe accident, jobs that are new or have changed, and jobs complex enough to need written instructions. For each step the analysts ask what can go wrong, what the consequences would be, how it could arise, what other factors contribute and how likely it is.

    OSHA says to review an analysis periodically and in particular after an illness or injury on that job, to train the people affected whenever it is revised, and to make clear that the job is being evaluated, not the employee's performance. HSE's five steps to risk assessment (identify hazards, assess the risks, control the risks, record the findings and review the controls) rest on the same logic at a wider scale. HSE says a written record is required if you employ five or more people, and that controls should be reviewed when workplace changes could lead to new risks.

    What a job safety analysis record holds in software

    • The task and its scope, location, equipment, version and date, with the person who prepared it and the workers consulted.
    • Ordered job steps, each with the hazards identified (what can go wrong, the trigger, who is exposed, the consequence) rather than a single list for the whole job.
    • Controls for each hazard, recorded in the order considered (eliminate, substitute, engineer, administer, protect), with an owner for any not yet in place.
    • The sign-on of the people who will do the work, kept per use or per shift where the work changes.
    • Review triggers and dates: scheduled, after an incident or near miss, and after a change of equipment, material or method.

    JSA, risk assessment and permit to work

    A JSA examines the steps of one task. A broader risk assessment can cover an area, process or range of activities, and a permit to work authorises one specific job at a specific time. A JSA often feeds a permit as the hazard analysis the permit refers to, and a permit does not replace it. Some organisations use the JSA for the reusable analysis of a task and a short check on the day for the live conditions; naming which is which stops a laminated template being treated as an assessment of today's work.

    A hypothetical example: replacing a light fitting above racking

    This case is invented and describes no real site. A maintenance technician is asked to replace a light fitting above racking in a warehouse. The preparer watches an experienced colleague do the job and lists six steps: position an access platform, isolate the circuit, remove the old fitting, fit and wire the new one, test, and clear away. The hazards are recorded step by step rather than as one list. Positioning the platform puts it on a route used by forklifts, so a barrier and a spotter are added. Isolating the circuit raises the question of proving it dead, so the isolation is recorded and tested before work starts. Removing the fitting at height creates a dropped-object risk for anyone in the aisle, so the aisle below is closed.

    The technician and the supervisor review the draft together, and the technician points out that a racking beam prevents the platform being placed where the draft assumed, which changes the first step. The corrected analysis is signed by both. Three months later a near miss on a different task shows that the same type of platform tipped on a sloping floor, so the analysis for this task is reviewed and a floor check is added. The record keeps the earlier version, the reason for the change and the names of the people who were told.

    Common misunderstandings about JSA

    • A JSA is not a form that proves safety. It is a way of thinking through the job; a signed sheet copied from last time shows that paperwork was done, not that the hazards of today's task were considered.
    • Generic analyses are not task-ready. A template for working at height cannot know about this platform, this aisle or this weather, so it needs a check against the actual conditions.
    • Workers are not just recipients. OSHA's booklet stresses involving employees because they know the job, and an analysis written only at a desk tends to miss steps.
    • A JSA is not a one-time document. It needs review after a change, an injury or a near miss, and OSHA notes that hazards missed in the first analysis may turn up on review.

    How JSA relates to other glossary terms

    A JSA is the task-level member of a family of hazard analysis methods, and it hands its output to the controls that surround the job.

    • HIRA: the broader process of identifying hazards and assessing risk, of which a task-level analysis is one form.
    • Permit to work: the authority to do a specific job, which refers to the analysis rather than replacing it.
    • Lockout/tagout: isolation steps often appear as controls in the analysis of maintenance tasks.
    • Management of change: a changed method or material should trigger a review of the analyses that depend on it.

    Records and evidence that usually exist for JSA

    • The analysis for each covered task, with version, date, preparer and the workers consulted.
    • The selection logic: how tasks were prioritised for analysis (injury history, severity potential, new or changed work).
    • Sign-on records showing who read the analysis before starting, where the procedure asks for it.
    • Links to permits, isolation records and incident reports for the same task.

    What a software tool needs to capture for JSA

    • Task templates with step-by-step hazard and control fields, not a single free-text box.
    • Version control that keeps earlier analyses and shows what changed and why.
    • A confirm-on-the-day step to record site conditions and any difference from the template.
    • Sign-on by the people doing the work, with mobile or offline entry for people in the field.
    • Review triggers tied to incidents, near misses and changes, as well as scheduled review dates.

    Catalog profiles documenting job safety analysis records

    Same rule for every product: tagged “Risk Assessment”, “Hazard Management”, “Safety Management”, “EHS Management”, “EHS”, “Construction Safety”, “Permit to Work”, “Permits to Work (PTW)” or “Control of Work”, with a sourced job safety analysis (JSA/JHA) or pre-task planning capability in its record, or one the vendor stated to us, labelled as vendor-stated. Documented and conditional capabilities qualify; check the linked scope before treating a module as included.

    Frequently asked questions

    How does a JSA differ from a broader risk assessment?

    A JSA examines the steps of a particular task. Broader assessments can address an area, process or range of activities.

    When should it be reviewed?

    Review it when relevant work conditions, equipment or knowledge change, and at intervals required by the applicable system.

    What makes a useful digital record?

    A traceable task version, hazards, controls, participants and review history that the people doing the work can access.

    Who should prepare a JSA?

    The people who know the job, ideally the workers who do it together with a supervisor or safety adviser. OSHA's booklet says involving employees helps minimise oversights and gets workers to buy in to the solutions.
