Traditional emergency lighting and exit signs have been primarily focused on guiding the interior occupants of a building to the nearest exit in the event of an emergency. Today, an additional emphasis is being placed on not only getting occupants to the exit of the building, but also getting them to and along a path of safety once they are out of the building. The NFPA Life Safety Code requires emergency illumination of the path of egress away from the building (exit discharge) and leading to a public way. The safe public area or public way is described in the code as a street or alley or other similar parcel of land essentially open to the outside air deeded, dedicated or otherwise permanently appropriated to the public for public use and having a clear width and height Outdoor emergency applications fall into two categories: damp location or wet location. According to Chapter 1, Article 100 of the 2002 National Electric Code, damp locations include ...partially protected locations under canopies, marquees, roofed open porches, and like locations... whereas wet location is partially defined as ...locations subject to saturation with water or other liquids, such as vehicle washing areas; and in unprotected locations exposed to weather.
