โฮมเพจ / coal mill explosion-proof valve design
Early electrical components were veritable Zippos in a mine, and would ignite coal dust easily. The term explosion-proof appeared to describe components that would not cause ignition via a spark. Obviously, a bit of a misnomer – if you throw a ton of C4 at a solenoid valve, it'll explode no matter its explosion proof rating.
