A new Industrial Hygiene (IH) Sampling Guide has been developed at the U. S. Army Environmental Hygiene Agency (USAEHA). Sampling procedures for over 100 compounds are described. The Guide contains minimum and maximum air volumes, recommended sampling rates and times for time weighted average (TWA), ceiling and short-term exposures, and the proper collection media for air sampling. It also addresses the types of containers and amount of sample required for bulk samples. This IH Sampling Guide is used by all Army industrial hygienists and industrial hygiene technicians involved in workplace monitoring. It enables the field personnel to sample using methods that are compatible with the Agency's state-of-the-art laboratory procedures.
