A Job Task Analysis (JTA) should include which elements in exposure sequencing?

• A. Data collection plan only
• B. Tasks, durations, exposures, controls, and data collection plan
• C. Exposures only
• D. Tasks only

Answer: (B)

In exposure sequencing for a Job Task Analysis, you map what workers do, how long each task takes, the exposures present in that task, the controls in place or planned to reduce exposure, and how you will collect data to verify exposures and control performance. Each piece fits together: tasks define the work happening; durations show how long workers are exposed and help assess cumulative exposure; exposures identify the hazard level during the task; controls describe what reduces that hazard and how effective it should be; and the data collection plan provides a method to measure exposures and evaluate control effectiveness across the sequence. Leaving out any element breaks the completeness of the analysis and hinders the ability to prioritize protections or verify results. So all five elements are necessary for a thorough exposure sequencing in a JTA.
