What type of waste container should needles and glass slides be discarded in?

Laboratory glass and plastic waste items that are not considered sharps can puncture regular waste bags and injure our janitorial staff.

Laboratory glass and plastic waste includes the following items:

• micropipette tips
• serological pipettes
• test tubes
• swabs/sticks
• other contaminated items that do not fall under the definition of sharps

Note:  Pasteur pipettes, used or unused, must be disposed of as sharps waste.

Biologically uncontaminated pipettes:

If these items have not been in contact with materials that contain infectious agents, including human and non-human primate-derived material, or recombinant/synthetic nucleic acid molecules:

• Place into sturdy cardboard boxes that will not weigh more than 25 pounds when full.
• Label boxes with the room number and seal the box with packaging tape and clearly label as "Laboratory Glass."
• Place the 'Laboratory Glass' box next to the regular trash container for pick-up by janitorial staff was regular trash.

Biologically contaminated pipettes:

If these items have been in contact with potentially infectious materials, such as body fluids, cell debris, or other materials that may contain infectious agents or recombinant /synthetic nucleic acid molecules there are several acceptable practices for collection, treatment and disposal:

• Collect items in a sharps container and autoclave when container is ¾ full. Dispose of autoclaved, locked sharps container into the regulated medical waste container.
• Pipette safe keepers are alternate methods to dispose serological pipettes. Serological pipettes could be collected in them, sealed, autoclaved and disposed in regulated medical waste boxes.

• Pipette washers or 5-gallon buckets may be lined with two autoclaveable biohazard bags and used for pipette segregation. When the bag is full, pipettes can be treated by autoclave and then disposed of into the regulated medical waste box. Do not over fill the box
• Waste pipettes may also be collected in a receptacle containing disinfectant (i.e., pipette washer) at the time of use. A biohazard label and identification of the disinfectant should be on the receptacle. At the conclusion of procedures, the pipettes can be drained and transferred from the receptacle to a biohazard bag for treatment by autoclave. Place into regulated medical waste container for disposal.

Definition

Materials that qualify as “sharps” are defined at the state level and shall be disposed of as Potentially Infectious Medical Waste (PIMW). In Illinois, the Illinois Environmental Protection Agency (IEPA) has designated the following material (used or unused) as sharps:

• Any medical needles,
• Syringe barrels (with or without needle),
• Pasteur pipettes (glass),
• Scalpel and razor blades,
• Blood vials,
• Microscope slides and coverslips,
• Glassware contaminated with infectious agents.

All sharps shall be disposed of in approved Sharps Disposal Containers (SDCs), which are provided free of charge to university personnel. SDCs are closable, puncture resistant, leak-proof on the sides and bottoms, and available in three sizes (1-quart, 2-gallon, or 8-gallon sharps disposal container). Because the IEPA requires sharps to be rendered unrecognizable prior to disposal, disposal of sharps in the regular trash is forbidden.

Chemical Contamination

Syringes, needles, and glass Pasteur pipettes used in chemical manipulations with no infectious agents should be free of visible liquids. Dispense liquids into a chemical waste accumulation container before placing sharps in an SDC. However, if sharps are exposed to acutely toxic waste or heavy metals, collect the sharps in a puncture-resistant container with a screw top lid, such as a wide-mouth Nalgene container, instead of an SDC. Use similar containers for glass slides contaminated with heavy metals.

Sharps with radioactive contamination should be collected based on the biological or chemical agents involved. Use shielding if there is an external radiation hazard. The containers should be properly marked to indicate the radiation hazard and the radiological information (isotopes and activity) should be provided in the pickup request.

Broken Glassware

Broken glassware is not necessarily considered to be a sharp. Broken glass that is not biologically, chemically, or radiologically contaminated may be disposed of in the regular trash. For more information see Laboratory Glassware Disposal

Precautions When Filling SDCs

When new SDCs arrive, secure the lid by snapping all corners in place. SDCs must be easily accessible to laboratory personnel and located as close as possible to the area where sharps are used. When discarding sharps:

• Never bend, shear, break, or recap disposable needles or remove from disposable syringes;
• Place the item into the SDC immediately following use;
• Never reach into the SDC;
• Never empty the contents of the SDC into another container;
• Never remove the lid from the container;
• Never overfill a sharps disposal container; no materials should be sticking out the top;
• Never force materials into a sharps disposal container.

Improper Use of SDCs

NEVER dispose of these items in SDCs:

• Plastic items (except for syringes),
• Beverage containers (no pop cans!),
• Non-biologically contaminated laboratory glassware,
• Solvent/chemical bottles,
• Light bulbs,
• Any paper materials,
• Pipette tips,
• Plastic pipettes,
• Silicon wafers,
• Aerosol cans or cans of any type,
• Scintillation vials,
• Any item with liquid (except for blood in vacutainer tubes).

Oversized Sharps

Oversized items for disposal, such as a 20-liter flask contaminated with an infectious agent, may be carefully boxed in an ordinary cardboard box for collection. The box must be sturdy and no larger than 18" x 12" x 9". Bottom seams on the box should be taped and the bottom lined with absorbent laboratory bench paper. Items should be emptied of all liquids before being packaged. The box lid should be closed and seams secured with tape. The box should be labeled on two sides with the words “OVERSIZED SHARPS”. Materials not packaged in this manner will not be collected.

Requesting New SDCs

Campus Stores manages the distribution of new SDCs. Requests for new SDCs are made by phone at 217-244-0139 or by email and should include quantity and size of SDCs and delivery location. Containers are usually delivered within three business days. If new containers are broken, cracked, or are missing parts, contact Campus Stores. 

Requesting Full SDC Pickups

When full, lock the lid in place, and request a sharps pick-up from the Division of Research Safety. Containers are usually picked-up within three business days.

Disposal of Personal Use Needles and Syringes

Individuals who have medical reasons for using sharps while on campus should refer to our personal use pages for students and employees.
