Collected Publications Related to the Use of Elevators During Fires (NIST SP 983, May 2000)
In the wake of the September 11 attacks in the US provisions for emergency egress from tall buildings are being re-examined, worldwide. Possibilities being discussed include the utilization of protected elevators with stairways for both occupant egress and fire service access. These have been discussed over the years and have been the subject of research by a number of parties, including a cooperative program between NIST, the National Research Council of Canada, and the US elevator industry.
