Exit Access – a corridor, an aisle, a path across a room, or a short stair or ramp that conducts the occupants of a building to an exit.
Exit – a protected means of evacuation (door opening, an enclosed and protected exit passageway leading to a door, or an enclosed exit stair or ramp) from an exit access to a safe discharge point, must be of 2 hour construction with self closing doors rated at 1 1/2 hrs.
Exit Discharge – a means (door, protected exit corridor, path across a ground floor vestibule or lobby) of moving from an exit to a safe discharge point (public way or other large open area.)
The minimum distance between exits is one-half the diagonal measurement of the building or the space served by the exits. On an open floor, this is measured as a straight-line distance between exits. Where the exits are joined by an exit access corridor that is protected from fire as specified by the building code, this distance is measured along the path through the corridor.
Most buildings require at least two separate exits. These must be as remote from each other as possible and arranged to minimize the possibility that a single fire or other emergency condition could simultaneously render both exits unsafe or inaccessible. With only minor exceptions, the access path to an exit may not pass through kitchens, restrooms, storerooms, workrooms, bedrooms, hazardous areas, or rooms subject to being locked. Two Remote Exits
Maximum travel distance to the nearest exit is specified by the code. Travel distance is always measured along the actual path occupants must take to reach an exit. There are two way to measure as shown on the diagram. The code will dictate which way you must measure it.
