Which of the following types of data would be part of a department's internal data collection?

The correct response highlights the significance of exposure records as vital components of a department's internal data collection. Exposure records document the circumstances and details surrounding employee exposure to hazardous materials or situations while on duty, making them crucial for assessing workplace safety and ensuring compliance with safety regulations. These records are maintained internally by the department as part of health and safety protocols to monitor and mitigate risk, providing a basis for improving safety measures and response strategies.

Incident reports, while important, typically detail specific events or accidents and may not encompass the broader range of ongoing exposure data. Employee evaluations focus more on performance and skill assessment rather than safety exposure tracking. External audit reports, while useful for compliance and accountability, originate from outside the department, examining practices from an external perspective rather than contributing to internal data collection practices. Thus, exposure records stand out as an essential internal data collection component.
