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.

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 ...
Layers of protection analysis (LOPA) is a technique for evaluating the hazards, risks and layers of protection associated with a system, such as a chemical process plant. . In terms of complexity and rigour LOPA lies between qualitative techniques such as hazard and operability studies (HAZOP) and quantitative techniques such as fault trees and event trees.
A simple element of risk quantification is often introduced in the form of a risk matrix, as in preliminary hazard analysis (PreHA). The selection of the methodology to be used depends on a number of factors, including the complexity of the process, the length of time a process has been in operation and if a PHA has been conducted on the ...
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.
It is a field of study within occupational safety and health and public health. [3] Short term risks may include physical injury (e.g., eye, back, head, etc.), while long-term risks may be an increased risk of developing occupational disease, such as cancer or heart disease. In general, adverse health effects caused by short term risks are ...
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)
