Angela, the only "requirement" I know of is your need to store solvents that could ignite if the thermostat switch sparks. We have one for special stains. We also have one that has one bottle of acetone in it. The vapor from that could ignite. 

They aren't that much more expensive than a regular refrigerator. They just put the thermostat switch on the outside rather than the inside.

What is the criteria for volume and NFPA rating of a reagent for a flammable / explosion proof refrigertor?
I know many of us do not have the necessary refrigerator, but I would assume there should be some kind of criteria or "rule" to help justify getting an equipped refrigerator  for flammable refrigerated reagents.
Please let me know some facts!
