Abstract
An emergency escape/fire fighting and building maintenance system including columns mounted to the exterior of a building for guiding either an escape slider or a fireman or maintenance lift. Each column has an inner and outer face which either assists in controlling the rate of descent of the escape slider or provides a means for allowing a fireman's lift or maintenance lift to climb the columns. The slider includes a harness and a body member which is engageable with and slidable down the column. The body member includes brake pad surfaces to provide an automatic braking system in the event the user is unable to maintain the desired escape posture and control his descending speed. Manual braking system is added to the alternate slider designs. The slider is intended to be used by able bodied persons since its descending speed is in part to be controlled by the user himself. After this system is placed into service, sliders for disabled persons and/or those physically not too fit persons may be developed at a later date.
