Biohazard cleanup activities remove, alter, dilute, flush, and destroy biohazards. Blood and other potentially infectious materials (OPIM) contain infectious waste. When wet, moist, or dried in flakes, blood we consider blood as biohazardous waste. Produced as a result of human activities, we expect to encounter biohazardous waste on all violent crime scenes, violent suicides, and unattended deaths with decomposition.
