In the US the "winky" receptacles that go (-|) or (⊣|) - except the T faces the other way - are 20 amp outlets, 120 volts. every receptacle that differs from the "shocked face" means something. Our standard shocked face receptacles are 15A. In hospitals, you need a guarantee that your monitors or assistive devices aren't going to trip a breaker somewhere if someone plugs in a vacuum; making it impossible to use the receptacle for something else is something that only matters after it's too late, i'd think.

In hospitals, they're colored differently to denote which sockets are on backed up lines vs not.
How can, say, a cleaner tell the prong configuration on a plug when it's plugged in and not visible?
none, but they sure cant plug in their vacuum.
hispital ones are red wires
Right but the point isn’t to stop something being plugged in, it’s to stop something unplugged
