Unless the wall receptacle was wired backwards. ;) (One would hope this happens significantly less often in a medical facility than in a residence…)

Clear plugs presumably allow users to periodically visually check the robustness of the conductor/pin connection.

When moulded plugs were first introduced there was a serious reliability problem, with melting, sparks and smoke. Moulding techniques had to be considerably refined. I think a two-step process is used, with a visual inspection between the steps. -- OOO - Own Opinions Only. With best wishes.
