It is imperative to use an explosion proof fan when working with flammable objects as the littlest spark or even heat build up in the fan could cause an explosion. While explosion proof fans are more expensive than their non-explosive counterparts, however, the safety they provide is worth every penny.
Explosion proof refrigerators are manufactured encased in steel. Their cabinet interiors are sparkproof with a non sparking magnetic door gasket with foam in place.
