n the context of occupational health and safety, a JSA is a systematic procedure to identify and control hazards associated with a specific task. The process involves breaking a job down into a sequence of individual steps, identifying the potential dangers within each step, and then prescribing preventative measures to mitigate those risks. Also known as a Job Hazard Analysis (JHA), this practice is particularly vital in high-risk industries like construction and manufacturing to prevent workplace injuries and illness. The JSA methodology focuses on the relationship between the worker, their tools, and their environment to ensure consistent and safe work methods.
