Abstract

A system for the evacuation of occupants of a high-rise structure in an emergency, expressly designed to be located within the high-rise structure itself. The system comprises an evacuator which operates over a 10-floor or more distance within a fire inhibiting tubular structure such as a shaft, wherein the evacuator is mounted on a centrally disposed tube mechanically descending from the upper level of the shaft to its lower level with occupants onboard, and wherein this system includes a series of such tubes, such that when occupants on the higher floors descend to the lowest level of the first shaft, they may exit to a second shaft and move to the next unit of the evacuator until they have descended to safety.
