Frequently Asked Questions about Chemical Waste Management:
How do I get my chemical waste picked up? Chemical waste pickup requests should be made online using the chemical waste pickup request form.
Does EHRS provide chemical waste containers? EHRS provides various types and sizes for collecting chemical waste. These containers and other waste supplies can be requested using our online form.
What do I do with empty chemical containers?
Most empty chemical containers must be “triple rinsed” before defacing the bottle’s label and then following the building’s recycling/disposal protocol. Below are two exceptions:
1. Empty containers that held EPA-defined acutely toxic (P-listed) chemicals must be managed as hazardous waste and given to EHRS for disposal. DO NOT TRIPLE RINSE these containers.
2. Empty containers that should not or cannot be “triple rinsed” with water should also be collected as chemical waste. Some reasons to not “triple rinse” a bottle for disposal will be if the chemical is: reactive (water-reactive chemicals if residual chemical remains, like sodium metal), odiferous (smelly, like thiols/mercaptans), or impervious (water will not do anything to remove the contents such as hydrophobic oils or organosilanes). Empty containers of odiferous materials should be placed into a bag and stored inside fume hood until EHRS collects them for disposal. For more information, see Disposal Guidance for Empty Chemical Containers.
What do I do with chemically contaminated pipettes/tips? Pipettes and tips that are contaminated with hazardous chemicals can be given to EHRS for disposal. Additional information about the disposal of contaminated items can be found on our website.
How do I schedule a Laboratory Clearance? The procedures for having your lab cleared by EHRS can be found on our website.
How do I get additional chemical waste labels? Additional chemical waste labels can be ordered and other waste supplies can be requested using our online form.
How do I dispose of unknown chemicals? Unknown waste materials must be managed as hazardous waste until testing is performed by EHRS staff. Containers of unknown materials must be labeled with a yellow chemical waste label. Please provide any available information about what the material could potentially be.
What chemicals can I pour down the drain?
Hazardous chemicals must never be poured down the drain as a method of disposal. Contact Jim Crumley of EHRS if you have specific questions about drain disposal.
