High Hazard Unit
The High Hazard Unit inspects employers with the highest incidence of preventable occupational injuries and illnesses and workers' compensation losses. Employers may also be selected and targeted by utilizing data sources such as, but not limited to, workers' compensation loss data, history of Cal/OSHA citations, and other data sources as provided in Labor Code section 6314.1.
