What is a Job Hazard Analysis (JHA) vs. a Job Safety Analysis (JSA) difference, if any?

• A. JHA is a different concept from JSA and they never overlap.
• B. JHA and JSA are often used interchangeably; both involve breaking down tasks to identify hazards and implement controls.
• C. JHA focuses on hazards, while JSA focuses on job performance.
• D. JHA is always more formal than JSA.

Answer: (B)

Both analyses share the same approach and goal: take a task, break it down into steps, identify hazards at each step, and decide controls to reduce risk. In practice, JHA and JSA are often used interchangeably; there isn’t a strict separation that makes them different concepts. Some organizations use one term to emphasize hazard identification across steps, while others use the other term, but the process and outcome are the same—a task-based safety plan with steps, hazards, and controls. The idea that they never overlap, or that one is solely about hazards while the other is about performance, or that one is always more formal, isn’t generally true in real-world use.
