NIOSH issued a document describing the Health Hazard Evaluation (HHE) Program and how local health departments can use its services to help meet their public health missions. The agency suggests considering HHE when exposures to unregulated agents are occurring; conditions and exposures are causing health effects; the situation represents an emerging hazard with exposures and health effects that are not well understood; new sampling methods need to be developed to accurately assess the work environment; or the effectiveness of exposure controls needs to be evaluated.
