Waste Handling, Decontamination/Disinfection, and Disposal
D. Contaminated Waste
2. Plastic Ware
iii. Small Non-sealable Items. (pipette tips, cryovials, microfuge tubes)
These are to be placed directly into the active Virkon solution inside the 2 litre bottles. The 2 litre bottles are then sealed by the user at the end of the work session, removed from the biosafety cabinet, and placed in the sink area for at least 20 minutes. The liquid inside the bottles should then be disposed of down the sink with plenty of water and the small items can be tossed into the large red-bag-lined autoclavable biohazardous waste buckets.
