- Dilute liquid waste with bleach (1 part bleach to 9 parts liquid waste) before pouring it down the drain.
- Occasionally, liquid waste is autoclaved. Do not add bleach in this case. Read Autoclaving Guidelines for Biohazardous Waste for more information.
The disposal method for sharps depends on whether they are contaminated with a hazardous material, and the type of contaminant. Whether contaminated or not, specific packaging and container restrictions apply.
Medical waste includes all laboratory trash that has not been contaminated by biohazards, chemicals, or radioactivity.
- Bag waste in a regular trash bag and place it in a locked dumpster or trash compactor, depending on your building. Check with your lab manager for details.
- Red biohazardous waste bags that have been decontaminated by autoclaving can also be disposed of in a locked dumpster or trash compactor. Make sure waste is double-bagged and labeled as described in the biohazardous waste guidelines.
