JSA — Job Safety Analysis

A structured risk assessment used to identify hazards associated with a specific job and define the controls required to perform the work safely.

Definition

Job Safety Analysis (JSA) is a systematic process that breaks a work activity into individual steps, identifies the hazards associated with each step and establishes the controls necessary to eliminate or reduce the associated risks. JSAs are completed before work begins and are widely used to communicate hazards, verify worker understanding and support safe execution of maintenance, construction and operational activities.

Why It Matters

Job Safety Analysis helps ensure that work is planned and executed with appropriate hazard identification and risk controls.

In Practice

JSAs are commonly completed jointly by supervisors and work crews immediately before commencing work and are frequently reviewed if work conditions change.

Common Misuse

A Job Safety Analysis evaluates the hazards of a specific task, whereas a Process Hazard Analysis evaluates hazards associated with an entire process or facility.
