Job Safety Analysis
Job safety analysis (JSA), also known as job hazard analysis (JHA), activity hazard analysis (AHA) or risk assessment (RA), 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. More specifically, a job safety analysis is a process of systematically evaluating certain jobs, tasks, processes or procedures and eliminating or reducing the risks or hazards to as low as reasonably practical (ALARP) in order to protect workers from injury or illness. The JSA process is documented and the JSA document is used in the workplace or at the job site to guide workers in safe job performance. The JSA document is also a living document that is adjusted as conditions warrant.
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. A more detailed JSA can be performed by breaking the job into steps and identifying specific hazards and control measures for each job step, providing the worker with a documented set of safe job procedures. Some JSA processes also include a risk assessment that lists the probability of each hazard occurring and the severity of the consequences, as well as the effectiveness of the control measures. The US Army Corps of Engineers uses a risk assessment code (RAC) to analyze the level of risk associated with each job step. For more information on RAC, see USACE AHA FORMAT.
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.
Workers and management need to understand that documentation will not make the job safe. Rather, workers and management must understand the risks and hazards associated with the job and know how to use the chosen controls in such a way as to eliminate or mitigate those risks. The JSA documents the decisions of this process.

Famous quotes containing the words job, safety and/or analysis:
“More than ten million women march to work every morning side by side with the men. Steadily the importance of women is gaining not only in the routine tasks of industry but in executive responsibility. I include also the woman who stays at home as the guardian of the welfare of the family. She is a partner in the job and wages. Women constitute a part of our industrial achievement.”
—Herbert Hoover (1874–1964)
“There is always safety in valor.”
—Ralph Waldo Emerson (1803–1882)
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
