Job Hazard Analysis

Job safety analysis (JSA), also known as job hazard analysis (JHA), is a safety management tool in which the risks or hazards of a specific job in the workplace are identified, and then measures to eliminate or control those hazards are determined and implemented.

The JSA process begins with identification of the potential hazards or risks associated with a particular job. Once the hazards are understood, the consequences of those hazards are then identified, followed by control measures to eliminate or mitigate the hazards.

The end result of a JSA is an easy to understand document that can be shared with workers as part of pre-job and safety meetings, and/or included as part of worker job descriptions. The JSA process can be used to help refine safe work procedures described in safety manuals or standard operating procedures, and the JSA document can serve as a useful tool in training new employees.
