Bio-hazardous Waste

Proper segregation, storage, treatment, and disposal of biohazardous waste is essential to reduce personnel exposure to potentially infectious materials. Waste containers for biohazardous waste and disposal of biohazardous waste are provided for by the hazardous waste laboratory; either can be requested through the work order system.


A high degree of caution should always be used when handling any sharp object, contaminated or not. All disposable sharps (hypodermic or other needles and syringes, Pasteur pipettes, scalpel or razor blades, blood vials, glass test tubes and centrifuge tubes, microscope slides and cover slips, and any other laboratory glassware that has had contact with infectious agents) must be placed into an approved sharps container immediately following use to reduce puncture risk. An approved sharps container is one that is leak-proof, puncture-resistant, closeable, and bears the biohazard symbol.

Solid Non-Sharps Biohazardous Waste

Wastes such as cultures, stocks, pathological wastes, animal carcasses, and related debris are to be stored in bags and containers bearing the biohazard symbol. Containers for these wastes are provided by the hazardous waste laboratory. While in use for waste storage, containers must be secured in a manner that will eliminate spillage. Do not put any sharps into these containers. It is important that the weight of any biohazard container does not exceed 60 pounds
