Welcome to the World Trade Center Evacuation Study Survey

The World Trade Center Evacuation Study of the Mailman School of Public Health at Columbia University is a three year collaborative study to determine the individual, organizational, and structural factors associated with evacuation from the World Trade Center (WTC) on September 11, 2001.

The information from your WTC experience may help to inform evacuation procedures, employee safety training, building design, codes and standards.
