Continuing in a series of strange things that I have seen while consulting at hospitals…
The discharge door for a stairwell opened out onto the 1st floor corridor, where egress was just down the corridor. (This is permitted by section 7.7.2 of the 2012 LSC, provided they met all of the other requirements).
As the picture indicates, when the stairwell door is fully opened, it sticks out into the corridor about half the width of the door. This can cause a momentary obstruction to people in the corridor when the door is open.
The facilities department thought it would be a good idea to warn people that the door may be a problem when open and created this sign on a swivel that warns people. To be sure, the sign does swing if anyone came into contact with it, but when it is in its normal position, it projected more than 4-inches into the corridor.
Even though the intentions for the sign were good, it does violate the maximum 4-inch corridor projection rule adopted by CMS, and therefore it was written up.
