Chemicals that cannot be identified are considered unknown
hazardous wastes. EH&S cannot, by law, pickup any waste from
your lab that is "unknown". It is the responsibility of each
laboratory, shop or chemical user to identify and know the contents
of all hazardous wastes.
If your are unable to identify the unknown, EH&S may obtain a sample for analysis to be performed by an outside laboratory. This process can be expensive; in most cases the costs will be borne by the lab or person(s) generating the unknown hazardous wastes.
To avoid generating unknown hazardous wastes in the future follow these steps:
Determining the contents of an “unknown” hazardous waste is an involved and costly process and also presents unique concerns and hazards for chemical waste handlers, UB EHS staff, and to the environment. Please take care to avoid creating “unknown” hazardous wastes in your laboratory.
