Ralph,
Was the DCM and/or ethyl acetate used for their "solvent' properties (extractions, dissolving, etc.)? If so, I'd characterize it as D001, F002, F003 (ignitable, toxic); DOT 3(6.1) pgII UN1992 Flammable liquids, toxic n.o.s (Dichloromethane, Hexane).
Jeff
We have an organic research lab that is producing solvent waste mixtures that are about 50% DCM and 50% hexanes and ethyl acetate. Does anyone know where I might find information for this mixture that might tell us whether this should be stored as flammable waste or non-flammable?
Thanks for any information on this.
