I didn't usually like to get involved in your and Geoff's love fests, but your statement about hospital grade outlets is incorrect.
From UL: In addition to complying with the general use requirements, hospital grade receptacles are specially designed and are subject to additional requirements of the standards. These include additional grounding reliability, assembly integrity, strength and durability.
As you can see, nothing about being explosion proof. All the literature indicates that hospital grade outlets are mostly differentiated from general use outlets by more robust construction and greater clamping force.
Carry on. And maybe don't be so quick to accuse Geoff of making stuff up when it seems you are not completely innocent yourself..
