What are examples of biohazardous waste?

Examples of biohazardous waste include used needles and lancets, blood collection tubes, saturated dressings, suction canister contents, laboratory cultures and specimens, live vaccines, and human or animal tissue. Contaminated personal protective equipment counts when it is saturated enough to release liquid under compression. A gauze pad with dried blood usually does not. That saturation threshold is where most facilities over-segregate and end up paying for biomedical waste treatment they never needed.
