I would classify it as flammable (primary hazard), toxic (subsidiary hazard) as DOT Hazard Classes are: 3 & 6.1 per 49 CFR 172.101

At 50% hexane this is definitely flammable.

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.
