Job Hazard Analysis
A Job Hazard Analysis is a step-by-step method for looking at a specific job or task to find the dangers involved and figure out how to reduce the risk of injury to workers. It breaks a job into its individual steps, identifies what could go wrong at each step, and determines controls to make the task safer. It is also commonly called a Job Safety Analysis (JSA).
A Job Hazard Analysis (JHA), also referred to as a Job Safety Analysis (JSA), is a systematic technique that examines the individual tasks or steps within a specific job or activity to identify associated hazards and their risks, and to determine control measures that mitigate those hazards. The process typically involves describing how each task is performed, identifying the hazards inherent to each step, and specifying controls intended to reduce the risk of worker injury. As an occupational safety tool, a JHA addresses task-level hazard identification and control selection; it is one component of a broader safety and health management system and does not by itself constitute a complete program. This entry is educational and not a substitute for professional safety or legal advice, and specific regulatory obligations may vary by jurisdiction.
Why it matters
Workplace injuries frequently originate not in a job as a whole but in specific steps within a task where a hazard goes unrecognized or uncontrolled. A Job Hazard Analysis matters because it forces a deliberate, task-level examination of how work is actually performed, surfacing dangers that broad safety policies may overlook. By breaking a job into its individual steps and asking what could go wrong at each one, a JHA helps organizations move from general safety intentions to concrete, actionable controls tied to real activities.
A JHA is also a practical tool for embedding safety into everyday operations rather than treating it as an abstract obligation. Because it documents how tasks should be performed and the controls intended to reduce risk, it can support worker training, guide the selection of appropriate protective measures, and provide a shared reference point when tasks or conditions change. Its value depends on how thoroughly it is conducted and how faithfully the resulting controls are implemented and maintained.
It is important to recognize what a JHA is not. It addresses task-level hazard identification and control selection, but it is only one component of a broader safety and health management system and does not by itself constitute a complete program. Nor does completing a JHA guarantee that injuries will be prevented; outcomes depend on implementation, worker adherence, and ongoing review. Specific regulatory obligations related to hazard analysis may vary by jurisdiction and should be confirmed with qualified safety or legal professionals.
