Emergency lighting is undergoing many changes. Some of the changes are driven by experience and others are driven by improved technology.
A Dept. of Commerce report and a Maryland Fire Protection Engineering study are two examples of how non-electrical lighting (Photoluminescent, aka glow-in-the-dark materials) are used to mark exit pathways:
Following the 1993 bombing of the WTC several improvements were made to egress lighting by including battery operated emergency lighting and photoluminescent floor strips.
- Now the NFPA Life Safety Code and International Building Code have provisions for photoluminescent or self-luminous exit path markings. The significant difference here is that the LSC has provisions for this, but leaves it up to the occupancy chapters to mandate it and none do at this time. In the IBC, such marking is now required in exit stair enclosures and exit passageways in high-rise buildings that contain assembly, business, educational, institutional, mercantile and hotels. (See 403.5.5and 1024.)¹
- Photoluminescent materials glow-in-the-dark because they store energy received from ultraviolet light emitted by the sun or by most artificial lights. The stored energy is then released as visible light in darkness.²
Photoluminescent materials may be molded into plastic or mixed into paint. They glow-in-the dark to highlight signage, stairs, walls or railings to mark exit paths.
Carbit has developed No. 377 Safety Marking Paint to meet the standards established by ANSI, ASTM and the NYC Code for photoluminescent paints. This paint is particularly useful in providing floor level luminous egress path markings, as specified in NFPA 101 and required in the model codes (IBC, IFC),and many local codes.
