Procedures for Biosafety Level 1 and 2
Cultures, Stocks and Related Materials Bulk Liquid Waste, Blood and Blood Products All liquid biohazardous waste from humans or animals such as blood, blood products, and certain body fluids can be disposed of directly by flushing down a sanitary sewer. All other liquid biohazardous waste needs to be autoclaved prior to disposal. Sharps Sharps must be placed in a rigid, puncture resistant, closable, and leakproof container that is labeled with the word “Sharps” and the biohazard symbol. MSU approved sharps containers are available through General Stores. Food containers (e.g., empty coffee cans) are not permissible as sharps containers. Sharps must be handled with extreme caution. The clipping, breaking and recapping of needles is highly discouraged and dangerous. Sharps containers should not be filled more than 2/3 full. Filled sharps containers must be closed securely (use the attached lid) and labeled with an MSU materials pick-up tag. Do not store used and closed sharps containers for more than 90 days. Never place any type of sharps in the lodal. Contact the ORCBS for sharps pick-up and incineration. Contaminated Solid Waste Contaminated solid waste includes cloth, plastic and paper items that have been exposed to agents that are infectious or hazardous to humans, animals, or plants. These contaminated items shall be placed in biohazard bags and decontaminated by autoclaving. Double or triple bagging may be required to avoid rupture or puncture of the bags. Contaminated pasteur pipettes are considered sharps and need to be disposed of in a sharps container. Waste Specific Procedures for Biosafety Level 3 Biohazardous waste including risk group 2 and 3 agents that are handled at Biosafety Level 3 is to be autoclaved at the point of origin (laboratory, or facility). In addition, this waste may be incinerated. Please contact the ORCBS for special instructions. Transportation of un-autoclaved waste outside of the building is not permitted. |
