IBC  The vestibule can be ventilated via natural IBC or mechanical means IBC  Stair Pressurization is an alternative means to achieving a smokeproof enclosure system IBC  Stair Pressurization is very commonly done with fans situated at the roof or ducts leading from the outside wall.*  Refer to diagrams from IBC commentary How Does Duct Wrap Become Relevant?  These ducts are required to be protected, IBC  To protect the integrity of the duct (keep it from collapsing)  To keep the air ventilation system moving into the vestibule exit stairwell during fire situations  …” shall be protected by opening protectives in accordance with section 715 for shaft enclosures”, IBC  JHA’s will accept duct wrap as a shaft alternative, driven by its design flexibility.

Fire Events – Smoke Control and Egress 69 West Washington Building The occupants who were still in the southeast stairwell above the 12th floor after 5:10 pm remained exposed to smoke and heat after the door to the 12th floor was opened. Smoke conditions in the stairwell were moderate when the first occupants entered the southeast stairwell. The air quality in the stairwell became progressively worse after the firefighters breached the door on the 12th floor, which allowed smoke from the fire floor to flood the southeast stairwell.
