Health Hazard Evaluation program
A Health Hazard Evaluation (HHE) is an evaluation of possible health hazards at a workplace. Employees, employee representatives, or employers can request an HHE if they have concerns about health hazards at work. During an evaluation, NIOSH investigators evaluate whether a health hazard to employees caused by exposure to hazardous materials or conditions exists. Workplace agents NIOSH has studied include chemicals such as lead, bromopropane, and chloramines; biological agents such as anthrax and mold; and physical agents such as heat stress, noise, radiation, and ergonomic stressors.
