Whenever laboratories close, move, or choose to clean out a substantial amount of material, the EH&S Chemical Waste Program (CWP) can perform a laboratory waste cleanout. This service includes management for unwanted reagents in good condition, samples and waste mixtures.
- Biohazardous waste, radioactive waste, empty containers, lab equipment, and lab supplies are not part of the lab cleanout
- Lab personnel are responsible for labeling their waste with a hazardous waste label or surplus sticker, before the chemicals can be picked up
- Laboratories must have at least 100 chemicals to be considered for a cleanout.
- Reagent chemicals in non-leaking and intact containers with an original manufacturer’s label are considered surplus chemicals (as opposed to hazardous waste) and may be candidates for our chemical redistribution program.
- Samples must be completely identified with a Hazardous Waste Tag. They may be grouped if compatible and similar composition.
- Waste Mixtures must also be fully labelled.
- Materials left behind by former occupants of the space are managed as part of the lab cleanout.
- CWP cannot accept unknown materials. If you have materials that are unlabeled or otherwise unknown, you must make all reasonable efforts to identify them. If you still cannot identify a material, you may request an unknown material analysis.
- Ensure proper segregation of chemicals.
- Do not combine incompatible materials in boxes or trays.
- You must provide a description of all materials to be removed before the cleanout. Use the online form. Include the following:
- Total number of chemical containers
- General description of the contents of each container (e.g., assorted buffers, non-halogenated solvents, toxic solids, flammable liquids, acids, or mercury containing materials)
- General condition of the containers
- Whether any containers are stored in a freezer
The cleanout will then be scheduled, and we will notify the requesting party.
Costs will be recovered from non-research operations, such as housing, operations and maintenance (O&M), utilities, and facilities projects. A PTA (account number) and the name of an authorized approver on the account are required. To schedule a cleanout for non-research operations, click here and click on “Request this service”.
