Health Hazard Evaluations (HHEs)

Employees, union officials, or employers can ask the NIOSH Health Hazard Evaluation (HHE) Program to help learn whether health hazards are present at their place of work. NIOSH may provide assistance and information by phone and in writing, or may visit the workplace to assess exposure and employee health. Based on their findings, NIOSH will recommend ways to reduce hazards and prevent work-related illness. The evaluation is done at no cost to the employees, union official, or employers.

This website shares information about the Health Hazard Evaluation (HHE) Program and allows you to request an evaluation. You can also search thousands of HHE reports or contact us if you have a question.
