The terms "job" and "task" are commonly used interchangeably to mean a specific work assignment. Examples of work assignments include "operating a grinder," "using a pressurized water extinguisher" or "changing a flat tire." Each of these tasks have different safety hazards that can be highlighted and fixed by using the job safety analysis.
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 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 ...
Process safety management (PSM) is a practice to manage business operations critical to process safety. It can be implemented using the established OSHA scheme [1] or others made available by the EPA, [2] AIChE's Center for Chemical Process Safety, [3] or the Energy Institute. [4] PSM schemes are organized in 'elements'.
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 ...
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 ...
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 ...
