What this term means in maintenance
A Job Safety Analysis is a structured review of work steps, hazards, controls, and responsibilities before a task is performed.
How a JSA works
The job is divided into steps. For each step, the team identifies hazards and defines controls.
Hazards may include:
- Energy
- Height
- Confined space
- Chemicals
- Heat
- Moving equipment
- Lifting
- Sharp edges
- Pressure
- Poor access
Practical example
A motor replacement JSA covers isolation, lifting, cable disconnection, alignment, testing, and safe return to service.
Controls
Controls may include elimination, isolation, engineering measures, procedures, permits, PPE, supervision, and competency.
JSA and work order
The JSA may be attached to the work order or work package and reviewed before execution.
Common mistake
Copying a generic JSA without considering actual site conditions and task changes creates a false sense of control.
