Which item is included in the DOD IH Exposure Assessment Model?

• A. Re-Evaluation
• B. Gas Chromatography
• C. PPE inventory
• D. Safety training

Answer: (A)

In the DoD Industrial Hygiene Exposure Assessment Model, exposure assessment is treated as an ongoing, iterative process. Re-evaluation is included to periodically revisit exposure estimates whenever conditions change, new controls are added, or new data becomes available. This keeps the assessment current and ensures that protective measures continue to be effective and that any residual risk remains within acceptable limits.

Gas chromatography is a lab analysis method used to measure chemicals, and while it may provide data for the assessment, it isn’t a step of the exposure assessment model itself. A PPE inventory relates to ensuring protective equipment is available and appropriate, not the assessment steps. Safety training is part of broader hazard control programs, but not a defined component of the exposure assessment process.
