I don't know what "best practice" is. I ask my faculty to collect all of the vials in a plastic container (Gladware containers) or plastic baggie and to label the container/baggie with one of our haz waste labels with contents, etc. I collect these and give them to my waste hauler.

Subject: [DCHAS-L] GC/MS vial disposal?

Hi,

I have been CHO for about a year, so still pretty new.

One of the questions that has come up is What is the best practice for disposing of GC/MS vials after they have been used.. I was thinking you would uncap them add the excess sample to a hazardous waste bottle. But the faculty members tell me they don't have to remove that leftover 1-2ml of sample and solvent and they just put the vials into broken glass even if they are still half full with solvent.

Thanks.
