Job Safety Analysis (JSA)


What is Job Safety Analysis?
is a technique that focuses on job tasks as a way to identify hazards before they occur. It focuses on the relationship between the worker, the task, the tools and the work environment. Ideally, after you identify uncontrolled hazards, you will take steps to eliminate or reduce them to an acceptable risk level

Why JSA ?

One process, three goals

  • Proactive Safety: Identifies unsafe work practices & control measures before an accident occurs
  • Jobs for possible improvement in job methods in terms of safety /planning / scheduling / execution / operation
  • Increases the safety awareness of the employees and supervisors through their participation in establishing safe work practices
  • Creates a job training tool
    • New employee
    • Pre-job instructions, irregular jobs
  • Used for job observation
  • Aids in incident investigations
