Types of WasteTypes of Waste
1. Infectious Laboratory Waste
2. Pathological (biomedical) Waste
3. Broken Glass
4. Other “Objectionable” Wastes
Infectious WasteInfectious Waste Laboratory WasteLaboratory Waste
Waste Cultures and stock of agents that infectious to humans
Contaminated items used to inoculate, transfer or manipulate cultures or stock of agents
Waste from the production of biological agent that are infectious to humans Discarded live or attenuated vaccines that are infectious to humans
Waste that originates from clinical or research laboratory procedures involving communicable
infectious agents.
Infectious WasteInfectious Waste Blood & Regulated Body Blood & Regulated Body FluidsFluids
Human blood and blood components and products made from human blood (e.g. serum, plasma) in containers Solid waste saturated with dripping human blood or blood products.
Any body fluids that are visibly contaminated with blood, in containers or that could be released in a liquid or semi-liquid form from soaked solid waste items.
Infectious WasteInfectious Waste Infected Research Animal Infected Research Animal WasteWaste
Carcasses, body parts, and blood derived
from animals knowingly and intentionally
exposed 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…. Or testing of
pharmaceuticals
Infectious WasteInfectious Waste SharpsSharps
Items that can induce subdermal inoculation of infectious agents, or that can easily penetrate the skin, puncture waste bags and cardboard boxes, including: Needles & Syringes Needles & Syringes
Capillary Tubes Surgical Scalpels Surgical Scalpels
Slides and Coverslips
Sharps are considered infectious, whether contaminated with infectious agents or not.
Pasteur Pipettes
Shards of Contaminated Glass
Razor Blades Razor Blades
Pathological Pathological WasteWaste
Pathological waste does not include hair, teeth and nails.
Human tissue and body parts removed by trauma, during surgery , autopsy or studies, and which is intended for disposal.
Broken Broken GlassGlass
Any large items of non-contaminated BROKEN glass containers such as:
Bottles Burettes
Test tubes Beakers
Non- broken glass items must be recycled.
Non-recyclable, non-broken small bottles and glass containers can be disposed off in the normal trash
Broken Thermometers are considered Hazardous Waste, not broken glass
Disposal Methods: Disposal Methods: SharpsSharps1. Do not mix sharps and broken glass
2. Sharps must be collected in a “Sharps Container”
3. Sharps Containers must be rigid puncture, burst, and tear resistant
4. Sharps Containers must not be overfilled. Thou shall not force sharps into container.
5. Sharps Containers must be closed tightly and taped shut before janitorial staff can remove from laboratory
Infectious WasteInfectious Waste Non-autoclavable infectious waste, other
than sharps, (e.g. infected animal waste) must be collected in impervious, tear and burst-resistant red plastic bags bearing the biohazard sings and the words ”infectious waste” and must be stored in appropriate freezers.
Non-infected animal waste, will be disposed of by the UMD animal services.
Autoclavable WasteAutoclavable Waste Autoclavable infectious waste, must be
collected in impervious, tear and burst-resistant autoclave plastic bags, bearing the biohazard sings.
While in the laboratory, waste bags must be placed in a rigid waste collection container bearing the biohazard sign and labeled Infectious waste.
Waste must be autoclaved at 121 C for 60 to 90 minutes
Autoclavable Waste Autoclavable Waste Cont.Cont. After autoclaving, waste bag must be
cooled, drained from liquids, then placed in a dark trash bag.
Autoclaved waste is no longer considered infectious, but can be disposed off as normal trash.
Removal of the waste from laboratory and autoclaving is the responsibility of laboratory personnel.
Pathological Waste Pathological Waste disposaldisposal Pathological waste must not be autoclaved
All Human pathological waste generated outside of the Anatomy and cell biology dept. must be placed into impervious, tear and burst resistant bags, labeled as “pathological Waste” or “Infectious waste” and stored in appropriate freezers or cooler.
Pathological waste will be sent to the University Crematory for final disposal.
Pathological material from the Body Bequest Program will be handled by the anatomy Dept.
