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

Page 12: Infectious Waste Management. Types of Waste 1.Infectious Laboratory Waste 2. Pathological (biomedical) Waste 3.Broken Glass 4.Other “Objectionable” Wastes

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.
