Emerging Issues in High-Rise Building Egress
Traditional high-rise evacuation strategies that have been incorporated into model codes in the U.S. have been based on defend-in-place and/or partial evacuation and relocation. Based on the assumption that only a limited number of building occupants would be immediately affected by an event, typically a single fire, and that others entering from below will have already moved down, the capacity of vertical means of egress elements, primarily stairs, has been
sized to accommodate the largest occupant load of a single floor of the floors served. Events in the past 15 years where full evacuation of high-rise buildings was deemed necessary, or actually occurred, have caused a reconsideration of these strategies and assumptions. High-rise building occupants, as well as building designers, now recognize that there are vulnerabilities beyond the single fire scenario, including bombings, catastrophic power failures, toxic chemical releases, and biological agent releases, that would likely entail complete evacuations. Even where no actual need for a complete evacuation exists, there remains a public perception of potential for catastrophic events and a predisposition to evacuate.
