Description / Abstract:
These requirements cover floor proximity and other egress path
marking and lighting systems that provide a visual delineation of
the path of egress. These systems are also used to identify
significant egress path features such as doors, door hardware, door
frames, stairs, stair landings, stair banisters, obstacles, egress
symbols, information placards, and similar elements of the egress
path.
These systems are intended for installation and use as required
by building and fire safety codes such as the Life Safety Code,
NFPA 101; the Building Construction and Safety Code, NFPA 5000, and
the International Building Code sponsored by the International Code
Council.
These requirements cover photoluminescent egress path marking
system materials such as sheeting and adhesive-backed laminates.
They also cover paints, pigments or inks pre-applied to a
substrate. They are intended for installation where the facility
illumination is sufficient to activate the photoluminescent
material.
These requirements do not address the mounting integrity of path
markers intended to be secured by adhesive to a building element.
The suitability of this form of mounting for any given application
is outside the scope of this Standard.
Self-luminous systems include constructions as defined in
5.13.
Externally powered lighting systems include varying designs of
electric lamps that may be intended for connection to any
combination of normal power supply, emergency power supply, and
battery backup.
These requirements do not cover egress signs and lighting to be
used independent from a path marking system, such as EXIT signs or
other legally required legends or graphical symbols that are within
the scope of the Standard for Emergency Lighting and Power
Equipment, UL 924.
These requirements do not address the text or graphical symbol
content, or the configuration of path marker signs.
The term ²product² as used in these requirements refers to
egress path marking and lighting systems or any part thereof
covered by these requirements unless specifically noted
otherwise
