Medical Waste Management

The regulations:

In the state of California, medical waste is handled according to the Medical Waste Management Act, and certain jurisdictions are overseen and inspected by the California Department of Public Health (CDPH). Medical waste includes any biohazardous, pathology, pharmaceutical, or trace chemotherapy waste not regulated by the federal Resource Conservation and Recovery Act of 1976, as amended; sharps and trace chemotherapy wastes generated in the diagnosis, treatment, immunization, or care of humans or animals; waste generated in research pertaining to the production or testing of microbiologicals; waste generated in research using human or animal pathogens. This definition is taken from the California Medical Waste Management Act, California Health and Safety Code Sections 117600 - 118360, revised January 2017.

Options for waste treatment:

Medical waste must be treated prior to disposal. UCSB has a Medical Waste Management Plan that conforms to federal and state regulations and University policies.

  • Liquid medical waste may be chemically deactivated with an EPA-approved, tuberculocidal disinfectant and then discharged to the sewer system with an excess of water.
  • Solid medical waste must be
    1. Treated in an autoclave registered with CDPH at ≥ 121°C and 15 psi for at least 30 minutes or
    2. Taken away for treatment by a licensed medical waste hauler or
    3. Treated by a CDPH-approved method
  • Medical waste generated in campus vivaria is taken away by licensed medical waste hauler Medical Waste Environmental Engineers, Inc.



There are two annual training requirements incurred with the generation and treatment of medical waste: bloodborne pathogens regulations and autoclave use.

There is an in-person presentation on the bloodborne pathogens regulations that is scheduled quarterly in the months of January, April, July and October. The presentation is announced by email by way of the,,, and listservs. Subsequent training may be fulfilled online.

Annual training on autolave use for the treatment of medical waste is handled by the manager for the specific autoclave.
