本文描述了高层办公楼的疏散主要发生在出口楼梯上。其他疏散、逃生或救援设施，如电梯、梯子、绳索和直升机，在高层火灾中有助于挽救生命；但是，除了某些特殊保护的电梯外，这些其他设施都有其固有的局限性，在配备了适当设备的高层建筑中，依靠它们进行疏散是不可取的，也是不必要的。引用:ASHRAE交易，第81卷，第一部分，新泽西州大西洋城

This paper describes the evacuation of high-rise office buildings taking place predominantlyon exit stairs. Other evacuation, escape, or rescue facilities, such as elevators, ladders,ropes, and helicopters, have been instrumental in saving lives in high-rise fires; but withthe possible exception of certain specially protected elevators these other facilities haveinherent limitations, and dependence on their use for evacuation in properly equipped high-risebuildings is undesirable and unnecessary.
