- Biosafety cabinets must be decontaminated and the outer surfaces cleaned with a suitable disinfectant; decontamination must be done by a certified professional. Currently, Stanford University contracts with an outside vendor for this; call the vendor (number is found at https://ehs.stanford.edu/services/biosafety-cabinet-usecertification) to schedule an appointment. The Principal Investigator should present a receipt verifying that the paraformaldehyde decontamination procedure has been completed by the contracted biosafety cabinet certifier.
- Storage freezers should be emptied and the surfaces should be decontaminated with a suitable disinfectant. The former contents must be decontaminated by autoclaving or disposed of in a red bag. Cryostats and liquid nitrogen storage equipment must also be emptied and contents properly disposed of. If the Principal Investigator intends to stay at Stanford but not continue the APB approved project, then only the biological agents that were approved for use on the application need to be disposed.
- Account for all specimens stored outside the lab room. Specimens stored in a cold room or an incubator in an adjacent tissue culture room should be autoclaved or disposed of in a red bag.
- Medical waste such as used sharps containers or red bags must be disposed of and the storage areas for the medical waste cleaned with a suitable disinfectant.
- Any biohazard labels must be removed from surfaces. The outer surface of all equipment and any work surface must be decontaminated with a suitable disinfectant.
- The Biohazard /Universal Precautions signs must be removed from door.
