1. Introduction - Job Safety Analysis (JSA)


The purpose of this module is to understand what a Job Safety Analysis (JSA) is and to advise when to use it, how to develop it and f where it fits into the risk management process. It seeks to provide practical guidance for holders, operators, site senior executives, supervisors, contractors and persons who are responsible for safety. The module does not prevent other ways of achieving an acceptable level of risk from being adopted and followed.

JSA is one of several hazard identification and risk assessment tools used by the industries. It is a basic tool and its application and quality varies greatly. Used in the correct context, it can be a useful safety tool, however if it is used incorrectly or inappropriately, it can result in poor identification of hazards and may contribute to serious incidents.

The term 'job' and 'task' are commonly used interchangeably to mean a specific work assignment. There may be many individual tasks in a job and as such 'job' may be a more appropriate term. Similarly 'safety' and 'hazard' can also be used interchangeably.

As the term 'job safety analysis' is not restricted to only identification of hazards, but the implementation of controls and verification of the effectiveness of those controls, the term 'safety' will have a more appropriate meaning in the context of assessment of risk in a job.

Presently there are many different versions of JSAs operating in industries, including:

  • Job Safety and Environment Analysis (JSEA)
  • Task Hazard Analysis (THA)
  • Safe Job Analysis (SJA)
  • Task Safety Analysis (TSA)
  • Pre-Work Safety Check
  • Job Task Analysis

In general the JSA has the following two ways of understanding:

“Job safety analysis is an important part of a safety programme for stopping work accidents and illnesses. It is about looking at each job to identify and assess hazards and set up safe work practices”.

Or/and

“A JSA is a task oriented risk assessment which can be applied by a work team prior to undertaking a potentially hazardous activity. Generally the technique is applied on site for routine activities as a precursor to a safe working procedure. It uses job observation and experience as the basis for identifying hazards and controls to be used. It is a primitive, but helpful, qualitative safety analysis tool”.
