I used to spend a good deal of time on hazardous materials shipping, although not in connection with lab waste. While "just in case" or "err on the side of caution" is a good thing to do in many circumstances, if you are assessing this mixture for transportation, classifying as flammable (or other hazard) just in case is as contrary to regulations as failing to classify a hazardous material. The DOT wants you, and thus the trucker, to KNOW, one way or the other. In that context Rachel's suggestion of having your waste vendor profile the stuff is a good one.

If you want to you could have your waste vendor profile the waste for you, this is actually an important regulatory element, characterizing your waste stream. There would be a charge for this but in the end you will be confident in how you handle it and will have identified all the associated waste characteristics of which there may be more than just flammable as mentioned by another member.

> I prefer to use the Fisher web site to look up safety and SDS information, as everything is clear and easy to understand.
Thanks for sharing that resource. I note that the Fisher SDS states that "Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste.” Someone else shared a link to a 2016 EPA document that describes the regulatory process for the classification of waste solvents, assuming perfect information is available for the mixture. This guidance is at
https://www.epa.gov/sites/default/files/2016-09/documents/version_2_-_solvent_guidance_final_508_compliant_090116.pdf
Unfortunately, we don’t have enough specific information available for this waste mixture to use the EPA’s resource. So we will be erring on the side of caution and assuming it is flammable.
Thanks to everyone for sharing their thoughts on this question.
