Photo-luminescent (PL Egress) systems should be UL listed in accordance with national codes IBC/IFC 2009, 2012, and 2015. The minimum requirements of the performance characteristics for the glow are as follows:
1006.4 Performance of System
Emergency lighting facilities shall be arranged to provide initial illumination that is at least an average of 1 foot-candle (11 lux) and a minimum at any point of 0.1 foot-candle (1 lux), measured along the path of egress at floor level. Illumination levels shall be permitted to decline to 0.6 foot-candle (6 lux), average and a minimum at any point of 0.06 foot-candle (0.6 lux) at the end of the emergency lighting time duration. A maximum-to-minimum illumination uniformity ratio of 40 to 1 shall not be exceeded.
There are many other requirements of the performance relating to ADA and NFPA 101. The specifications set out by UL 1994 are the testing requirements for all of the components which make up the emergency egress system. PL Egress is quickly becoming the standard for Emergency egress in stairwells of high rise public facilities all over the world! The U.S standard for PL Egress systems is one of the best in the world and other countries are quickly following suit. GBC Safety Glow has long been at the forefront of PL Egress technology.
