Most wastes generated in the laboratories and shops located on campus are prohibited from disposal in the regular trash or down the drain.
Follow the protocol and request pickup using the request form.
Empty chemical containers can be disposed of in the regular waste stream by following
protocol.
- Make sure they have been emptied by normal means (pouring, pumping, etc.) so that no more than 0.3% by volume is left
- NOTE: Containers that previously contained chemicals listed on table 205a have additional requirements—contact EHS prior to disposing of these containers.
- NOTE: Aerosol cans are considered "empty" when all liquid has been expelled. Contact EHS for instructions on disposing of partially full aerosol cans
- Using Sharpies, write "Empty" and mark off the chemical name and hazard symbol.
- Rinse or air dry as appropriate.
- Put them in thick black garbage bag(s) or cardboard boxes and bring the bags directly to the dumpster. Do not put them in a regular trash bin
Broken glass that is not contaminated with chemicals, infectious agents, or other hazardous materials can be collected in either approved broken glass boxes or 5-gallon buckets with lids. Find more details here.
Follow your laboratory's biological safety manual and protocols. University biological safety Manual has some guidelines.
