Things that go bump (or don’t) in your egress stairwells

There has been a little increase in findings relative to various items (utility system components, security cameras, evacuation devices) being located in egress stairwells. NFPA 101-2000 Life Safety Code 7.1.3.2.1 (e) gets pretty specific about what you can have in terms of penetrations into and openings through an exit enclosure assembly:

(1) Electrical conduit serving the stairway

(2) Required exit doors

(3) Ductwork and equipment necessary for independent stair pressurization

(4) Water or steam piping necessary for the heating or cooling of the exit enclosure

(5) Sprinkler piping

(6) Standpipes

This means, strictly speaking, that things like security cameras, water lines, phone/radio system repeaters, electrical conduit that does not serve the stairwell, etc. are pretty much off the table, particularly if they have been installed after March, 2003 (the official dividing line between new and existing construction).

There is an exception for existing penetrations as long as they are appropriately protected (firestopping, etc.), but if you’ve got newer than ’03 stuff in your egress stairwells, you may have some work ahead to square things away (I’d start with a conversation with either your state AHJ or maybe the engineers at TJC).
