A.   Infectious Waste
          Infectious waste includes the following:
    Laboratory Waste "Laboratory Waste" means:
    • Waste cultures and stocks of agents that are generated from a laboratory and are infectious to humans.
    • Discarded contaminated items used to inoculate, transfer, or otherwise manipulate cultures or stocks of agents that are infectious to humans.
    • Wastes from the production of biological agents that are infectious to humans.
    • Discarded live or attenuated vaccines that are infectious to humans.
    • Wastes that originates from clinical or research laboratory procedures involving communicable infectious agents unless such waste has been properly decontaminated by an approved process (e.g. autoclaving).
    Blood "Blood" means:
    • Human blood and blood components and products made from human blood.
    • Solid waste saturated with dripping human blood or blood products (e.g. contaminated items that would release blood in a liquid or a semi-liquid form, if compressed).
    • Human blood products include serum, plasma, and other blood components.
    Regulated Human Body Fluids " Regulated human body fluids" means:
    • Blood and blood components.
    • Cerebrospinal fluid, synovial fluid, pleural fluid, peritoneal fluid, pericardial fluid, amniotic fluid, semen, pus, drainage, vaginal secretion.
    • Any body fluids that are visibly contaminated with blood, that are in containers or that drip freely or could be released in a liquid or semi-liquid state from soaked solid wastes items.
    Research Animal Waste " Research animal waste" means:
    • Carcass, body parts, and blood derived from animals knowingly and intentionally exposed to agents that are infectious to humans; and/or accidentally or naturally infected with agents that are infectious to humans for the purpose of research, diagnostic, production of biologicals and/or testing of pharmaceuticals.
    Animal waste generated at UMD consists of the following:

    • Non-Infected Research Animal Waste: Animals and animal waste that have not been in contact with agents that are infectious to humans or are not considered naturally infected.
    • Preserved animal Waste: Preserved animals that have been used in teaching laboratory .
    • Radioactive Research Animal Waste: Animals and animal waste contaminated with radioactive material.
    • Research Animal Waste Contaminated with Toxic Chemicals
    Sharps "Sharps" means:  Any discarded items that can induce sub-dermal inoculation of infectious agents, or any item that can easily penetrate the skin, puncture waste bags and cardboard boxes including:
    • Needles and syringes
    • Surgical, scalpel and razor blades.
    • Pasteur pipettes, capillary tubes.
    • Slides and cover slips.
    • Shards of contaminated glass, and any other sharps items derived from human or animal patient care, blood banks, laboratories, mortuaries, research facilities and industrial operations.

    Sharps are considered infectious waste whether contaminated with infectious agents or not.

B.  Pathological Waste
    "Pathological waste" means: Human tissue and body parts removed by trauma, during surgery or autopsy or studies and which is intended for disposal. Pathological waste does not include teeth, hair, or nails.
C.  Objectionable Waste
    Objectionable waste means:
    Waste that the WLLSD will not accept in their main processing plant, this includes:
    • Blood administration tubing.
    • Tubing or drainage collection devices (e.g. hemovacs, J.P. bulbs, and suction canisters), which cannot be emptied and/ or rinsed from all visible blood.
    • Wound dressing/ gauze, which contains spots of blood greater than 2 inches in diameter.
    • Large volumes of tubing disposed of in same container (e.g. waste bag full of IV and/or ventilator tubing).
D.   Broken Glass
    Broken glass means:
    Any large items of non-contaminated broken glass containers. This includes bottles, burettes, beakers, test tubes, etc.
