Vestibules in a high rise but what if there aren't smoke proof ancillary spaces?

I've always routed the pipe out and around a stairway. Thanks for the info.

Penetrations into and openings through an exit enclosure are prohibited except for required exit doors, equipment and ductwork necessary for independent pressurization, sprinkler piping, standpipes, electrical raceway for fire department communication systems and electrical raceway serving the exit enclosure and terminating at a steel box not exceeding 16 square inches (0.010 m2). Such penetrations shall be protected in accordance with Section 712. There shall be no penetrations or communication openings, whether protected or not, between adjacent exit enclosures. Is that what you are thinking of? Reed A. Roisum, CET Ulteig Engineers, Inc.
