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.
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 ...
A process hazard analysis (PHA) (or process hazard evaluation) is an exercise for the identification of hazards of a process facility and the qualitative or semi-quantitative assessment of the associated risk.
In 1974 a one-week safety course including this procedure was offered by the Institution of Chemical Engineers (IChemE) at Teesside Polytechnic. Coming shortly after the Flixborough disaster, the course was fully booked, as were ones in the next few years. In the same year the first paper in the open literature was also published. [4]

A work method statement, sometimes referred to as a safe work method statement or SWMS or a safe work procedure, is a part of a workplace safety plan. [1] It is primarily used in construction to describe a document that gives specific instructions on how to safely perform a work related task, or operate a piece of plant or equipment. In many ...
Each component is subject to a safety analysis to identify undesirable events (equipment failure, process upsets, etc.) for which protection must be provided. [3] The analysis also identifies a detectable condition (e.g. high pressure) which is used to initiate actions to prevent or minimize the effect of undesirable events. A Safety Analysis ...
In March 1993, BSI published the world's first occupational health and safety management systems standard, BS 8750, and in March 1996, BS 8800, as part of a response to growing concerns about the occupational health and safety. Before 1999 there was an increase of national and proprietary standards and schemes to choose from.
