Workers

​HESIS work on hazards in specific industries

The Hazard Evaluation System and Information Service, or HESIS , investigates new and unrecognized workplace hazards, provides early warning, and works to prevent illness and disease on the job. HESIS develops educational materials based on our work with certain industries and occupations. We work with employers, worker advocates, and others to distribute this information where it is most needed.
