The Job Safety Analysis (JSA) is also commonly known as a Job Hazard
Analysis (JHA) or a Task Hazard Analysis (THA). When done properly they
will identify which workplace hazards exist with a ‘possible or greater’
likelihood of occurring. Once identified, steps can be taken to reduce
the risk associated with the hazards listed in the analysis. This is
required to get the hazards to a point where it is acceptable and in
line with the principles of ALARP (As Low as Reasonably Practicable)
using a standard hierarchy of control.
