NOTE: Even if a material is known to be non-hazardous (i.e., blood from uninfected animals) it is impossible to distinguish from human blood or other infectious materials and has the appearance of being potentially infectious. Uncontaminated: Materials that are not contaminated with a potentially infectious substance, or materials that have been properly decontaminated by autoclave, bleach, or some other acceptable sterilization / decontamination method. Blood & Body Fluids: Any liquid blood or body fluids from humans or animals, excluding urine. Blood & Body Fluids Contaminated with Chemicals or Radioactive Materials: These must not go down the drain. Contact OEH&S for collection / disposal. Sanitary Sewer (drain) Disposal: Blood, body fluids, spent liquid media, and other potentially infectious liquids should be treated for 30 minutes with bleach before disposal down the drain. Red Biohazard Bins: Potentially infectious materials should be autoclaved, bleached, or treated in a manner which renders them non-hazardous before they are put into the red bins. Do not autoclave materials that have already been treated with bleach. BIOHAZARD BINS SHOULD NOT BE AUTOCLAVED. Broken Glass Boxes: All contaminated materials put into broken glass boxes should be autoclaved, decontaminated with bleach, or treated in another way which renders them non-hazardous. SHARPS should never be put into broken glass boxes, whether or not they are contaminated. Autoclave Treatment: Lab must buy autoclave bags. SHARPS containers, biohazard bins & liner bags are not autoclavable. Do not autoclave bleached items. SHARPS Disposal: Needles, razor blades, microtome blades, lancets, scalpels, etc. must ALWAYS be disposed of in a SHARPS container. Needles should never be recapped, sheared, bent or broken. The needle and syringe should be put into the SHARPS container as a whole unit, uncapped. SHARPS CONTAINERS SHOULD NEVER BE AUTOCLAVED.
