???Hi Ralph,

All of those components are flammable with the ethyl acetate and hexanes being more flammable than the dichlomethane. However, the dichloromethane is also carcinogenic posing more of a chronic health risk. I prefer to use the Fisher web site to look up safety and SDS information, as everything is clear and easy to understand. Fisher also provides color coding and easier pictograms than Sigma or Acros.

Also, I doubt that the DCM waste from the reaction will be stabilized (even if the solvent originally contained a stabilizer), but according to the Fisher site, stabilized or not, the FIRE rating is the same.

Info below.

Hope this helps!

Best,
Greglynn

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.

- Ralph
