The 2009 International Building Code and
the 2009 International Fire Code now require Photoluminescent Egress Marking Systems in
"buildings of Groups A,B,E,M,and R-1 having occupied floors located more than 75feet(2,860 m)
above the lowest level of fire department access in accordance with Sections 1024 and 1024.5."
New York City has already adopted their own code, RS-6 in 2006 and many other states are considering
or have adapted the 2009 IBC and IFC for egress marking systems.
A provision for application is included in the 2006 edition of the NFPA 101
Life Safety Code under Clause 7.10.1.7 which, is now required in the 2009 IFC and IBC.
Additional application requirements are being drafted by local and state authorities while
proposed performance standards are available from ASTM and are now established under UL 1994.
Way Marking does not replace Emergency Lighting Systems which are mandated nationally.
Rather, it is used to more readily define the escape route. In the extraordinary event that
the Emergency Lighting System fails, the photoluminescent markings are self-illuminated to ensure
visibility in total darkness.
