Explosion proof means that the elements that can trigger are isolated in a duct or explosion sealed boxes that contain ignition resulting repeatedly and will not spread outside the box. To this end, the box should be cast steel heavy with contact surfaces precision ground and many bolts at the joints with sufficient depth and minimal space to quench escape the hot flames below ignition. The boxes are not airtight and is presumed to contain vapors of explosive gases. If the volume is small, explosive strength it should contain is significant, but not huge.
Usually lighting requires sufficient electrical energy to cause ignition. Explosion proof lighting require these components: Explosion waterproof case with the switch or sensor / relays to activate lights or off. electrical energy into the conduit from the source to a safe area to the light switch box. A lighting fixture that holds the bulb so it can not be broken and cause a spark and cast metal bracket to hold the contact if it occurs.
