Which of the following is NOT a step in a Job Safety Analysis (JSA)?

• A. Selecting the task
• B. Breaking the task down into steps
• C. Conducting air monitoring for unrelated hazards
• D. Verifying effectiveness of controls

Answer: (C)

In a Job Safety Analysis, the focus is on understanding a task's sequence and the hazards that arise at each step, then deciding and validating controls to prevent injury. The process typically follows selecting the task, breaking it into steps, identifying hazards for each step, implementing and maintaining effective controls, and verifying that those controls actually reduce risk. Conducting air monitoring for unrelated hazards isn’t part of this task-by-task analysis; it’s an industrial hygiene activity used to assess exposure levels across environments or tasks, not a step in outlining how a specific job should be performed safely. So the option that isn’t a JSA step is the air monitoring for unrelated hazards, because it falls outside the structured analysis of a task’s steps and controls.
