Waste can often involve a mixture of medical and non-medical waste. Mixed waste is categorized as medical waste EXCEPT for the following:

  1. A mixture of medical waste and hazardous chemical waste is categorized as hazardous chemical waste and is subject to the statutes and regulations applicable to hazardous chemical waste.
  2. A mixture of medical waste and radioactive waste is categorized as radioactive waste and is subject to the statutes and regulations applicable to radioactive waste.
  3. A mixture of medical waste, hazardous chemical waste, and radioactive waste is categorized as radioactive waste and is subject to the statutes and regulations applicable to radioactive waste.

Mixed chemical and biohazardous sharps waste will be placed into a sharps container that is labeled as chemical sharps waste. Any mixed chemical and biohazardous waste must be properly identified and labeled with a Hazardous Waste Tag. Information on the Stanford University Chemical Waste programs can be found in Waste Disposal or call EH&S, (650) 723-5069.

All mixed radioactive-biohazardous waste must be properly segregated prior to disposal. Mixed radioactive and biohazardous non-sharps waste will be packed in a yellow bag labeled with the universal radiation symbol and/or radiation symbol. Mixed radioactive and medical sharps waste will be placed in a sharps container labeled with the universal radiation label. Mixed radioactive waste is picked up by Radiation Safety waste technicians and transported to the EH&S radioactive waste accumulation area for packaging and disposal. Call (650) 725-1408 for pick up and information regarding mixed radioactive-biohazardous waste.
