Study of Occupant Behaviour during 1993 WTC Evacuation

Most of the respondents in both towers never left the building or the floor when alarms went off or drills were held. Over 90% of the respondents in Tower 2 never evacuated the building and never moved to another floor. In Tower 1, 79% of the respondents never moved to another floor and 88% never evacuated. These results further explain the unfamiliarity with the stairs that many respondents reported, in spite of the fact that most of the occupants who responded to the survey were fire wardens.
