Lighting and Marking of Exits and Exit Routes

The lighting and marking of exits and exit routes is governed by OSHA at 29 CFR 1910.37(b)(1) thru (b)(7) the elements of which are listed below:
* Each exit route must be adequately lighted so that an employee with normal vision can see along the exit route.
* Each exit must be clearly visible and marked by a sign reading "Exit."
* Each exit route door must be free of decorations or signs that obscure the visibility of the exit route door.
* If the direction of travel to the exit or exit discharge is not immediately apparent, signs must be posted along the exit access indicating the direction of travel to the nearest exit and exit discharge. Additionally, the line-of-sight to an exit sign must clearly be visible at all times.
* Each doorway or passage along an exit access that could be mistaken for an exit must be marked "Not an Exit" or similar designation, or be identified by a sign indicating its actual use (e.g., closet).
* Each exit sign must be illuminated to a surface value of at least five foot-candles (54 lux) by a reliable light source and be distinctive in color. Self-luminous or electroluminescent signs that have a minimum luminance surface value of at least .06 footlamberts (0.21 cd/m2) are permitted.
* Each exit sign must have the word "Exit" in plainly legible letters not less than six inches (15.2 cm) high, with the principal strokes of the letters in the word "Exit" not less than three-fourths of an inch (1.9 cm) wide.

Provisions of state and local fire codes may also apply.
