Liquid biohazardous waste should be stored in a leak-proof container labeled as a biohazard.

Human or animal blood and body fluids can be flushed to the sanitary sewer by way of the lab sink without prior treatment, however decontamination prior to disposal is recommended if possible.

There are two different methods of decontamination that can be used:

1. Chemically disinfect the liquid waste using an appropriate disinfectant and following the manufacturer's specifications for use. The waste can then be disposed of down the sanitary sewer by way of the lab sink.
2. Autoclave the contaminated liquid waste and then dispose down the sanitary sewer by way of the lab sink.

Appropriate PPE should be worn when handling and disposing of liquid biohazardous waste. This includes: Splash goggles, gloves, and a lab coat.

Safety Notice: Do not chemically disinfect AND autoclave the liquid waste. Autoclaving chemicals is hazardous and should not be done.
