Abstract
Models to predict occupant response and evacuation will be an essential part of the move throughout the world toward performance-based codes and standards, as they are necessary for calculating the time required for occupants to reach safety, given a proposed design. To obtain realistic evacuation time predictions, it is essential to be able to accurately calculate the delay times occupants take before beginning evacuation. This paper reviews the findings from five evacuation studies. These studies include evacuation drills in midrise and highrise apartment'buildings and midrise office buildings. Findings from two fire incidents a six-fatality highrise apartment building fire in Canada and the World Trade Center bombing in New York City are also discussed. The findings of particular interest are those related to problems in alerting occupants, delays reported or observed during evacuations, and the reasons behind those delays.
