[GreenKeys] OT: Explosion-Proof phone on ebay...

[Don Robert House K9TTY]

This set and a companion model that sits on a desk are designed to keep any internal arcs from being exposed to a gaseous atmosphere.
They used to have a lot of applications for mines and pipelines.  The phones are supposed to keep explosions from occurring
not to survive any explosions.  The one on ebay is a wall mount set.
