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.

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.
Hazard identification and risk assessment: HIRA is a procedure of identifying the relevant hazards and assessing their risks applied to a project, and the results would be used to inform the planners on safety related issues such as choosing the appropriate diving mode, selection of equipment and dive team members, specialised training that may ...
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 ...
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 ...
The Particular Risk Analysis (PRA) looks for external events which can create a hazard such as a birdstrike or engine turbine burst. The Zonal Safety Analysis (ZSA) looks at each compartment on the aircraft and looks for hazards that can affect every component in that compartment, such as loss of cooling air or a fluid line bursting.
[a] It is a widely accepted system promoted by numerous safety organizations. This concept is taught to managers in industry, to be promoted as standard practice in the workplace. It has also been used to inform public policy, in fields such as road safety. [13] Various illustrations are used to depict this system, most commonly a triangle.
