A job safety analysis (JSA) is a procedure that helps integrate accepted safety and health principles and practices into a particular task or job operation.The goal of a JSA is to identify potential hazards of a specific role and recommend procedures to control or prevent these hazards.
For example, if employees must work high above the ground, the hazard can be eliminated by moving the piece they are working on to ground level to eliminate the need to work at heights. However, often elimination of the hazard is not possible because the task explicitly involves handling a hazardous agent.
Occupational risk assessments provide this information, allowing limits for safe levels to be put in place. By maintaining appropriate standards, employees’ well-being is protected. A United States public health organization that conducts occupational risk assessments is the National Institute for Occupational Health and Safety (NIOSH ...

A permit-to-work is not a replacement for robust risk assessment, but can help provide context for the risk of the work to be done. Studies by the U.K. Health and Safety Executive have shown that the most significant cause of maintenance-related accidents in the U.K. chemical industry was a failure to implement effective permit-to-work systems.

The first 30 pages of the document covers that process. The next 140 pages give an overview of the modeling techniques and how they should be applied. The last 160 pages give an example of the process in action. Some of the methods covered: Functional Hazard Assessment (FHA) Preliminary System Safety Assessment (PSSA) System Safety Assessment (SSA)
Some researchers have criticised control self-assessment as a flawed approach as the way risk is defined and measured is unsophisticated. In particular, control self-assessment may understate risk by not identifying extreme downside risk. An extreme downside risk is a highly improbable event that would have catastrophic consequences if it occurred.
Illustration of Exposure Risk Assessment and Management related to anticipation, recognition, evaluation, control, and confirmation. Occupational hygiene or industrial hygiene (IH) is the anticipation, recognition, evaluation, control, and confirmation (ARECC) of protection from risks associated with exposures to hazards in, or arising from, the workplace that may result in injury, illness ...
