My dad (an electrician) explained to me one time that ground-up is actually the way they’re supposed to be. If a plug starts to sag due to gravity or some other reason, the ground terminal will be exposed instead of the “hot” terminal. Basically, with the ground hole up, there’s a lower risk of accidental shock. It would also make sense that there would be less chance of a spark… which, inside a hospital with flammable gases everywhere, sparks are bad, mmmmm-kay. lol
