Which item is NOT part of the eight elements of the DOD IH Exposure Assessment Model?

• A. Create a Workplace Safety Audit Schedule
• B. Define Scope of Support and Resources
• C. Basic Characterization
• D. Establish similar Exposure Groups (SEGs)

Answer: (A)

The question is testing which item does not belong to the eight elements of the DoD industrial hygiene exposure assessment process. This model focuses on planning, scoping, data collection, exposure characterization, and grouping exposures to analyze risk and guide controls.

Defining the scope of support and resources is a planning step essential to any exposure assessment—the team, the data needed, and the resources available determine how the assessment proceeds. Basic characterization is a core activity, providing the initial description of processes, hazards, and exposure scenarios that form the basis for analysis. Establishing similar exposure groups (SEGs) is a practical technique within exposure assessment to organize data so comparisons are meaningful and manageable.

Creating a workplace safety audit schedule, while important for safety program management, is not one of the eight elements of the exposure assessment model itself; it’s a broader safety-management activity rather than a direct exposure assessment step.

So, the item that is NOT part of the eight elements is the workplace safety audit schedule.
