Hazard Evaluation System and Information Service
The Hazard Evaluation System and Information Service, or HESIS, is a program in the California Department of Public Health that uses scientific, medical and public health expertise to help prevent workplace illness and disease. To promote worker health and safety, HESIS:
- Identifies and evaluates new and unappreciated workplace chemical hazards
- Evaluates complex scientific information on potential hazards to determine what it means for people in real work situations
- Develops practical information and health alerts on chemical hazards for workers and employers
- Works with unions, employer groups, and others to distribute vital hazard information about workers at risk
- Recommends protective occupational health standards
HESIS is supported by an interagency agreement between the California Department of Industrial Relations and the California Department of Public Health.
