Fire fighting work of high-rise buildings has been an important safety work which is regarded by people and our parties, and is directly related to lives and properties of the countries and people, particularly for the general people, quick and safe escape is considered firstly when a fire disaster happens, and then the problem of property is solved.

In 11/15 th 2010, 58 deaths and 71 injuries of a huge fire accident occur in the Luzhou 728 apartment building in the quiet area of Shanghai city, and 1.58 billion yuan is directly lost. The teaching of blood sounds the alarm clock for our fire-fighting work in high buildings. Therefore, if a person in a high-rise building should escape quickly in the event of a fire, a more practical escape apparatus should be provided.

In spite of the current situation, no good scheme for rapidly, reasonably and safely solving the disaster situation of the high-rise building is seen at home and abroad. From the existing applied scheme, the escape device only solves the problem of escape of individual, good-performance and high-volume personnel, and is really unsmooth and fearful for most of the evacuees, women, children, old, weak, sick and disabled people and other special personnel. The existing escape equipment on the market comprises: domestic escape ropes, escape descent control devices, high-altitude flexible rescue escape channels, soft cloth slides and the like, foreign pocket parachutes, high-rise escape shoes, escape boxes and the like. These escape apparatus described above can only address the needs of individual persons, if available.
