Job safety analysis (JSA) is a procedure that helps integrate accepted safety and health practices into a particular task or job operation. In JSA, the ultimate goal is to identify potential hazards in every step of a process and recommend the safest way to execute the job. JSA is a written procedure developed to understand, review, minimize or eliminate hazards associated with work processes. A job safety analysis (JSA) must be conducted at the job site before the commencement of a job, or when there has been any modification done to the existing job process. JSA can also include risk assessment to evaluate the hazard occurance probability while also detailing the severity of its consequences, and the effectiveness of the control and preventive measures implemented.
