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.
