Wandering through the halls of an ER

Emergency gas shutoff valves.

Oh, I see. I'm looking at a map next to the object that it is pointing out.

Never seen so many push-buttons for opening the doors. 2 per corner, per side. Critical, I'm guessing.

Beds in the hallways are not being stored. The signs on the walls are actually "addresses" or "room numbers" for them that can be tracked as locations for where patients are.

Good thing it's not blocked.
