I am currently inspecting fire and smoke doors in a healthcare facility that was built in 2014. The central utility plant is separated from the rest of the hospital and has 2 hour cinder block interior barriers separating the chiller, boiler, pump, and electrical rooms. There are six different doors within the 2 hour barriers, three of which have no rating labels on the door or frame.
My question is, are there any codes that would allow the lack of rating labels because of the building being separated from the general public and patients? All penetrations along the walls are fire blocked, so my first thought is yes all doors within this 2 hour barrier require 90 minute labels, regardless of the stand alone aspect of the building or occupancy classification. I just wanted to ask people with abundant code knowledge on here, just in case i'm missing something. The staff, of course has budget concerns and hopes they are ok, I'm telling them otherwise.
