Fire Escape and Tour bus with tourists sightseeing in New York City, NYC. , Tribeca, Manhattan, New York City, New York. A fire escape is a special kind of emergency exit, usually mounted to the outside of a building or occasionally inside but separate from the main areas of the building. It provides a method of escape in the event of a fire or other emergency that makes the stairwells inside a building inaccessible. Fire escapes are most often found on multiple-story residential buildings, such as apartment buildings. At one time, they were a very important aspect of fire safety for all new construction in urban areas; more recently, however, they have fallen out of common use. A fire escape consists of a number of horizontal platforms, one at each story of a building, with ladders or stairs connecting them. The platform and stairs are usually open steel gratings, to prevent the buildup of ice, snow, and leaves. Railings are usually provided on each of the levels, but as fire escapes are designed for emergency use only, these railings often do not need to meet the same standards as railings in other contexts. The ladder from the lowest level of the fire escape to the ground may be fixed, but more commonly it swings down on a hinge or slides down along a track. The moveable designs allow occupants to safely reach the ground in the event of a fire but prevent persons from accessing the fire escape from the ground at other times (such as to perpetrate a burglary or vandalism).
