The neutral can be broken in some installations. One example is when wiring explosion proof equipment.
Cables usually aren't the problem for explosion proof electrics and electronics. Switches, (motor/generator)brushes, breakers and relays are a (much) bigger issue. Followed by things using, or emitting electro-magnetic radiation. I assume, if you want to be thorough, one could use cables with a higher insulation/shielding rating for further protection in an explosion-prone environment.
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.

No. Household wiring requires household wiring.
LEDs are not automatically explosion-proof. It would depends on the design as a whole. what type of switch that's used, how well it's encased, amount of current running through it, etc.
The National Electrical Code (NEC) requires that wiring in hazardous locations with a classification of 300.5 must be installed in a manner that prevents the spread of fire or explosion. This includes using approved wiring methods and materials that are suitable for the specific hazardous environment.
Coherence.
Theorems are statements in geometry that require proof.
