If you are generating moderate to high risk contaminated laboratory biomedical waste, which includes waste generated from working with human, animal, or plant pathogens, the procedure is slightly different. The soft waste and all pointed plastic or glass items should be placed in a red bucket. The red bucket provides additional assurance that this waste will be properly contained and no one will suffer a cut or puncture wound. To have red buckets delivered to your laboratory call 432-6545. Red buckets will only be delivered to laboratories generating moderate to high risk biomedical waste. If any waste sharps (which we should avoid when working with these agents) such as syringes, needles, or blades are generated, they should be placed directly into a needle box. Needle boxes continue to be available from the stockroom. All of the moderate to high risk waste must continue to be autoclaved or chemically treated before being placed in the carts or large bag-box units. This decreases the exposure risk to personnel handling this waste. These waste containers should be labeled with Yale's new sticker that identifies them as containing moderate risk materials and identifies the type of treatment imposed on the waste prior to being picked up by EHS.

• Sharps (i.e. needles, razor blades, scalpel blades)
