Job Safety Analysis (JSA)

A Job Safety Analysis (JSA), which OSHA calls a Job Hazard Analysis (JHA), is a technique that focuses on job tasks as a way to identify hazards before they occur. It examines the relationship between the worker, the task, the tools, and the work environment. ^[1] The method works by breaking a job down into a sequence of basic steps, identifying the potential hazards associated with each step, and then determining the preventive measures, or controls, that eliminate or reduce each hazard. ^{[1] [2]} CCOHS, which uses the same three-stage logic, recommends keeping the breakdown to roughly ten steps or fewer so the analysis stays clear, and laying the result out as a worksheet with three columns: the job steps, the hazards at each step, and the controls. ^[2] Controls are selected using the hierarchy of controls, which ranks measures from most to least effective: elimination, substitution, engineering controls, administrative controls, and personal protective equipment. ^[4] A JSA is typically done for jobs with high injury rates, jobs that could cause severe harm even without a history of incidents, jobs where one error could be serious, and jobs that are new or have changed. ^[1] Its output is not the end of the process: the documented safe method feeds directly into the safe work procedures and training that workers actually follow on the job. ^[2]

Key characteristics

• Breaks a job into a sequence of basic steps, usually around ten or fewer. ^{[1] [2]}
• Identifies the specific hazards associated with each individual step. ^{[1] [2]}
• Determines a control for each hazard, ranked by the hierarchy of controls: elimination, substitution, engineering, administrative, PPE. ^[4]
• Commonly documented as a three-column worksheet: job steps, hazards, controls. ^[2]
• Prioritised for high-injury, high-severity, error-sensitive, new, or changed jobs. ^[1]
• Best done with the workers who do the job, whose knowledge improves the analysis. ^[3]

How SOPX handles this

A JSA defines the safe method on paper, but its value only lands if workers actually follow that method at the point of work. Once the JSA names the steps, hazards, and controls, SOPX turns the resulting safe procedure into a visual step-by-step SOP workers actually follow. A supervisor films the task or imports an existing document, and the AI structures it into clear steps, with the relevant hazard and control noted on the step it applies to. Workers reach the current version by QR code at the workstation, in 50+ languages, and Run mode lets them sign off each step as it is completed, giving you evidence the safe method was followed. Versioning means that when a JSA review changes a control, the updated procedure is live within minutes for every manufacturing or construction crew. SOPX documents the resulting safe procedure and carries it to the floor; it is not a risk-assessment tool or an EHS management system, so the JSA itself still lives in your safety process.
