Abstract
On September 11, 2001, two airplanes hit WTC 1 and 2 sixteen minutes apart, which forced one of the largest evacuations from high-rise buildings in U.S. history. By understanding human behavior during evacuation from the Towers, improvements can be made to evacuation education, training, and procedures for high-rise buildings across the world. Path analysis is used to analyze telephone data obtained from WTC survivors to empirically determine if the theories from community evacuation hold true for building fires. Results show that community evacuation theories do hold true for building fires; specifically in WTC 1 and 2. In general, longer evacuation times were predicted by witnessing a higher environmental cues, being on a lower floor in the building, obtaining more information, viewing the event as more serious (higher risk), seeking additional information, and performing a higher number of pre-evacuation actions.
