It is a very personal matter what I consider important; for others, it might be relatively unimportant. Both variants have disadvantages and advantages; nowadays, both are done depending on who considers what important.
Exactly, it is a personal assessment of risk and taste. My thought only regarding the argument with the “unconscious person lying in front of the door and the emergency service can’t get in”: if the emergency service is already there, they will not be stopped by an ordinary living room door. If, as you described, it takes 1.5 hours to get to the person in an emergency situation (!), I would rather consider whether something else went wrong elsewhere. Seriously, wasting 1.5 hours in an emergency to climb through the window – on the upper floor? You destroy the door by kicking it in – assuming sufficient strength. The door frames are not made of concrete or steel but only glued. If you can’t get in that way, I would rather call the fire department, which will open the door with their tools – if necessary, even through the wall. But trying to climb the façade for 1.5 hours… I don’t know.
It becomes interesting if it is “only” a helping situation where you don’t need an ambulance or similar. Would you then want to destroy the door?! So one could construct something.
Another thought that crosses my mind: if someone is lying completely or partially in front of the door and unconscious, why can’t you get in? Yes, okay, it is more difficult, but the person is not leaning against it or concreted in place. If you open the door with sufficient force, you push the person behind it away. Okay, that is probably unpleasant for him, but he doesn’t notice it. As far as I see, the body would be pushed backward; there is still about 40 cm of space.
But as you say, everyone has to make their own risk assessment. It’s not about right or wrong, but the question was how one would do it. If you then state your reasons why you allow the door to open inward and personally do not see outward opening as mandatory and justify it accordingly, you should also be able to handle if someone would rather have it open outward. My 2 cents.
