How does data analysis relate to selecting and implementing controls during exposure assessment?

• A. Data analysis informs controls to reduce exposure
• B. Data analysis is optional if there is a plan
• C. Controls are determined before data analysis
• D. Data analysis is used only for compliance and not for controls

Answer: (A)

Data analysis ties measurements to action by revealing where exposure comes from and how big it is. By examining the collected data, you can see which tasks, processes, or conditions drive the highest exposures and how they vary over time or between workers. This insight shows where controls will have the greatest impact and helps you choose the most effective type of control—engineering controls to remove or reduce the source, administrative controls to change how work is done, or PPE when necessary. It also lets you prioritize interventions and set measurable goals for reduction. After implementing controls, data analysis is used again to verify that exposures actually decreased and to adjust as needed. In short, measurements become concrete, actionable steps through careful analysis, rather than just being collected for compliance or planned without data.
