Presentation: Defend-in-Place: When Evacuation is the Last Option
Description:
Total evacuation is not always the safest—or even viable—egress strategy. In high-rises, healthcare facilities, and detention centers, life safety design depends on defending occupants in place. This presentation examines the technical framework governing protect-in-place strategies under the International Building Code (IBC) and NFPA 101 (Life Safety Code).
We will explore how passive fire barriers, smoke compartmentation, horizontal exits, active suppression, and survivable voice communication (EVACS) integrate to maintain tenable environments. Attendees will gain practical insight into smoke barrier integrity, refuge sizing calculations, and the operational coordination required to satisfy code intent while safeguarding vulnerable populations. Join us for a deep dive into moving beyond traditional evacuation modeling to compartmented defense.
