What is an industrial hygiene sampling strategy?

• A. Identify tasks, select sampling methods, frequency, and analyze results to evaluate exposures and implement controls.
• B. Randomly sample without a plan.
• C. Sample only at the end of project.
• D. Use only one sampling method for all tasks.

Answer: (A)

Industrial hygiene sampling strategy is a planned, systematic approach to measuring worker exposures so you can protect health. It starts by identifying which tasks or activities could generate contaminants, then selecting appropriate sampling methods for each situation (personal, area, short-term, or time-weighted), deciding how often to sample to capture variability, and analyzing the results to determine if exposures meet or exceed limits. This process guides control actions and can be updated as conditions change, ensuring data-driven decisions about engineering controls, work practices, or personal protective equipment.

This approach matters because without a plan, sampling can be random and miss high-exposure tasks; sampling only at the end of a project leaves workers unprotected during most activities; and using a single method for all tasks ignores differences in contaminants, exposure routes, and measurement needs.
