Sorry Neil, but you're going to have to be specific about what is considered a "clinical area".
Also, which Standards (in general) are (or were) the buildings built to? "American", I should imagine.
From memory (in the absence of any over-riding Standard), the height of wall outlets in Minor OR and similar rooms was generaly set at 1300 mm FFL.
However ... what about the "cleaner" (vacuum, polisher) outlet? At low level (30 mm FFL?) and outside of the "patient zone" (hopefully). PS: I donated all my "Hospital Design" reference books to the office library for my mates in Riyadh before I left. But I'm sure that any of the well known "Engineering Consultants" could advise you, Neil.
