Subject: [DCHAS-L] Waste storage question
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.
