Biohazard & Crime Scene Cleanup Companies in California

California licenses this work. Companies that clean up trauma scenes (crime scenes, unattended deaths, serious injuries) must register with the California Department of Public Health as Trauma Scene Waste Management Practitioners (TSW). CDPH publishes the registered-practitioner list and updates it regularly; every California operator marked “verified” below appears on that list with its TSW registration number.

Before hiring in California, ask for the company's TSW number and check it against the CDPH medical waste program registry.
