The events of September 11, 2001 have generated renewed
interest in the use of protected elevators for egress
and access. U.S. building codes contain requirements for
accessible elevators for assisted evacuation of people
with disabilities. Firefighter lifts, required in tall
buildings in some countries, are being discussed to
improve both the safety and efficiency of firefighting
operations. The desire for increased egress capacity of
tall buildings to facilitate simultaneous evacuation has
rekindled interest in elevators as a secondary means of
egress for all occupants. Elevators used for each of
these purposes share many of the same design
characteristics and the need for an extraordinary level
of safety and reliability.
