Medical Waste Procedures
Solid waste is collected in red biohazard waste bags in secondary containment, treated at a minimum of 121°C for at least 30 minutes in an autoclave permitted with CDPH.
After the autoclave cycle has been confirmed, autoclaved waste is disposed of in the red or brown-lidded toters designated for laboratory waste.
Do not retain solid medical waste for longer than 7 days at room temperature.
Liquid waste is treated with an EPA-approved, tuberculocidal disinfectant and then dispensed down the laboratory sink with an excess of water. Tissue culture liquid waste is typically deactivated by aspirating it into 100% bleach. Add spent media until the bleach is diluted 10-fold to 10% final vol/vol, allow to set for a minimum of 20 minutes, and dispense down the laboratory sink with an excess of water.
Do not retain liquid medical waste for longer than 7 days at room temperature.
Trace chemotherapeutic and pharmaceutical waste, other than RCRA hazardous waste or Controlled Substances, is disposed of through EH&S as chemical hazardous waste. Residual solids and contaminated items (including sharps) are collected in a rigid, lidded container labeled with "CHEMO" on the Hazardous Waste Container label. Chemical hazardous waste must be picked up by EH&S Hazardous Waste within 270 days of the accumulation start date.
Biohazardous/medical sharps disposal procedures are described above, and the complete campus medical waste management plan is available on the Medical Waste tab.
