Abstract
On February 26, 1993, shortly after noon, a bomb exploded in a garage below the World Trade Center plaza in New York city. The explosion and subsequent fire caused extensive structural damage on several basement levels, interfered with the operation of the fire protection and other emergency systems and resulted in the evacuation of tens of thousands of occupants of the complex. The National Fire Protection association (NFPA) and the National Research Council of Canada (NRC) undertook a research project, funded by the National Institute of Standards and Technology, the General Services Administration, NFPA and NRC, to study the human behavior of building occupants in this incident and to document, to the extent possible, those engineering details such as building design, fire safety features, and smoke spread, that effected behavior. The purpose of this project was to collect and preserve human behavior data. The information gathered will aid in the understanding of what people do in fires and why and how those actions may conform to or differ from the assumptions used in designing and planning for life safety in such a large building. Results will help in work toward the improvement of fire safety in similar occupancies and to enhance the knowledge needed in the development of emergency evacuation models. Surveys were sent to fire wardens and other members of tenants' fire safety teams, a total of 1,598 people, a sample that covered every occupied floor and was of a manageable size. The bomb was placed closer to Tower 1 than Tower 2 and responses to many of the questions differ between occupants of the two towers.
