What is a Job Safety Analysis?

A Job Safety Analysis (JSA) is a careful analysis of the hazards and controls for a particular job.

Similar terms to a JSA are:

  • Job Hazard Analysis (JHA)
  • Activity Risk Assessment (ARA)
  • Safe Job Analysis (SJA)
  • Total Risk Assessment (TRA)

More information about the JSA is available in the EP-HSE-ROM-HAZ.GRP.INS.0002.ENG on GEMS 

Why is a JSA important?

  • It helps to ensure that work will be carried out safely
  • It is a supporting document for a PTW
  • It forms part of a Safe System of Work (SSOW) which is a legal requirement
  • It is useful for newcomers who are unfamiliar with a job
  • It assists the supervisor to deliver a Toolbox Talk

What’s the difference between a JSA and a Risk Assessment?

A JSA is a type of risk assessment and is a careful study of a job. For each step in a job, you identify the hazards and the controls required to eliminate or reduce each hazard.

A risk assessment can be used for a location/ activity/ equipment. It involves the identification, evaluation, and estimation of the levels of risks, their comparison against benchmarks or standards, and a determination of an acceptable level of risk. A matrix is often used.
