Smoke Barrier Wall - Penetrations
What are the requirements for penetrations in smoke barrier walls?
Any examples are for illustrative purposes only.
Smoke barrier walls in existing health care and ambulatory health care occupancies are required to have a ½-hour fire rating. In new health care and ambulatory health care occupancies, smoke barrier walls are required to have a 1-hour fire rating. When sealing penetrations in these walls, a material that is UL listed for the appropriate fire rating must be used.

Smoke barriers are used to subdivide building spaces into smoke compartments. They restrict the passage of smoke and therefore through-penetrations must be sealed with a material capable of restricting the transfer of smoke.
