An elevator is not concealed within the construction of a wallor a floor/ceiling assembly. It has walls around it and doors at each floor, but not concealed within a wall. If that was the case, every room in a building with surrounding walls and a door would be considered concealed.

I know there's an elevator there cause I use it.

I know there is plumbing there cause I use it.....but it is concealed......No?

I guess we can have our own opinions of what concealed is. Mine is that an elevator is not concealed inside of a wall or floor/ceiling assembly. It is simply surrounded by walls. IMHO

I would submit that a glazed elevator hoistway is not concealed, as the interior of the hoistway is visible from outside of the hoistway.

And I would say the same for an exposed block shaft in an exposed "industrial" type setting....

IF the atmosphere of the elevator area is the same atmosphere as the are outside the elevator area, I would consider it open since nothing would contain or conceal smoke within the common area.....
