Simply put : An explosion proof refrigerator must be hard wired into an explosion proof junction box in a room with only explosion proof lighting, ventilation and switches. If you put a plug on an explosion proof refrigerator and put it into a normal lab area, it is a flammable refrigerator (sealed relays, no open compressors, magnetic locks) . 

So, a flammable refrigerator prevents explosions or sparking fires within the unit, explosion proof are guaranteed to not start a fire inside or outside the unit.

We do not recommend our students or employees working in flammable atmospheres, so we do not use/recommend explosion proof refrigerators/labs.

Hope this helps.
