Biological Waste Disposal

What you need to know

Colour

Yellow identifies biological waste items. Red identifies cytotoxic waste items. Red Yellow Image
Cytotoxic Waste

Cytotoxic waste is defined as any material that may have come into contact with a cytotoxic drug. Cytotoxic waste cannot be treated by just autoclaving; therefore this kind of waste must be segregated and sent off-site to be incinerated.

Biological Waste

Biological waste is waste containing biological material that has NOT been in contact with a cytotoxic drug, other hazardous chemicals or radioacitve materials.

Drop off site for The Department of Chemistry and Biology's biohazardous waste is Storage Room, KHN202D (located in Kerr Hall North). All other Departments must contact Eric Ambroise @ ext 3483 for details.
KNH 202D
Pick up site for The Department of Chemistry and Biology's biohazardous disposal supplies is KHN202D (same as drop off). All other Departments must contact Eric Ambroise @ ext 3483 for details.

Supplies

New supplies include flattened cardboard boxes, pails and liners. More detail is provided on each of the new items below.
Cardboard Boxes

All autoclave bags must be placed inside a box, tapped and placed in the designated room for disposal.

Boxes need to be assembled before autoclave bags can be placed in them. Follow the steps below to assemble a box.

Cardboard Boxes
How to assemble a cardboard box?

  • Obtain the flattened box from your designated storage room.
  • First assemble the bottom side of box by folding the two flaps down until the edges meet. Hold them in place and tape the bottom.
  • Place a liner inside the box (yellow or red).
  • Assembling a Box

Important: DO NOT put items that can puncture the liner. Use a PAIL instead.

Pails

Pails

  • Pails are for waste that could puncture a bag AND for chemical waste liquids.
  • Keep liquids in their original receptacles and close lids tightly before putting into pails.
  • Pails with solid waste can be fully filled.

Remember: Cytotoxic waste goes into RED pails while regular biological waste goes into YELLOW.

Tip: If you use a lot of plastic pipettes, it may be best to use a separate pail just for the pipettes. It can help you stay organized and can reduce the number of pails needed.

Here is what you should NOT be doing – USE A PAIL INSTEAD

What you should not do

DISPOSAL

New supplies include flattened cardboard boxes, pails and liners. More detail is provided on each of the new items below.
Autoclave Bags: If you currently have waste in autoclave bags, these must be placed inside a box with liner (yellow/red) before disposal. NOTE: The color of the old autoclave bag does NOT matter (only the colour of the box liner matters).

Waste Disposal

Sharps Containers (TRANSITION PHASE)
If you currently have sharps waste in sharps containers, these can be placed inside a box with liner (yellow/red) before disposal. NOTE: The color of the sharps container does NOT matter (only the colour of the box liner matters)Sharps Container
SEAL BOXES/PAILS (NEW)

Boxes: Close box lid and TAPE shut.

Sealed Box

Pails: Push white lid TIGHTLY onto bucket such that it locks into place

Pail Lid

Identification of Waste (as before)

Boxes: Write LAB INFO & DATE on side of box. I.e. – Smith Lab, KHW111, January 11, 2015.
Pails: Write LAB INFO & DATE on white lid. I.e. – Smith Lab, KHW111, January 11, 2015.
Labeling Cytotoxic Waste (New)

Boxes: If the box contains cytotoxic waste – PLACE Cytotoxic sticker on the box: Cytotoxic Sticker
Pails: Labels are NOT required. Use the appropriately colored pail.
Can I continue to collect the biological waste as I have in the past?

No. Everyone who produces biological waste must follow the new method and outlined procedures. We will no longer be autoclaving on-campus. Therefore, follow the steps outlined in this guide and get yourself familiarized with the new items (pails, boxes etc)

When do I drop off biological waste?

Biological waste is picked up by the third party every TUESDAY MORNING. We highly recommend that you drop of your biological waste to the storage room by Monday Evening.

Where do I get supplies?

The Department of Chemistry and Biology can obtain supplies from the Storage Room located in Kerr Hall North 202D. Some of the new supplies include pails (red/yellow), lids, liners and cardboard boxes. Other Departments should call Eric Ambroise @ ext 3483.

What do I put on the filled cardboard box/sealed pail?

Boxes: Write LAB INFO & DATE on side of box.For example – Smith Lab, KHW111, January 11, 2015

Cytotoxic Material: If the box contains cytotoxic waste, be sure to place  the cytotoxic sticker on the box (the sticker containers a red triangle with the letter C written inside)

Regular Biological Waste: Yellow sticker is placed on all cardboard boxes by default. You do not need to place any stickers for biological waste.

No stickers are needed for pails.

What goes in the box?

All biosafety bags that need to be autoclaved, sealed sharps containers and any other items that require the autoclave step. Be sure to NOT mix CYTOTOXIC and regular biological waste together.

What goes in the pails?

Pails are for waste that could puncture a bag AND for chemical waste liquids. The red pail is for cytotoxic waste while yellow is for regular biological waste. Pails with solid waste can be fully filled.

Pails should be used for items that have the ability to puncture a biosafety bag. The chemical liquid containers should be tightly closed before they are placed in the pails.

Where do I drop off cytotoxic/regular biological waste?

Currently, the drop off location is NOT the same as supplies pick up location for The Department of Chemistry and Biology.
