The U.S.-wide Building Codes require Luminous Egress Path Markings in multi-story building emergency staircases to help building occupants evacuate from darkened assembly, business, educational, institutional, hotel/motel, mercantile high-rise buildings nationwide. PERMALIGHT® manufactures these non-electrical, non-radioactive, photoluminescent Code-compliant, UL1994-listed Exit Path Markings. The comprehensive PERMALIGHT® Staircase Marking system includes photoluminescent Metal Stair Nosing, Anti-Slip Floor products, Perimeter Wall Tape & Extrusions, Handrail & Obstacle Markings, Directional Signs, Floor Identification Signage and Exit Door Markings, allowing building owners and property managers to choose markings that perfectly suit their building and budget needs.
PERMALIGHT® photoluminescent markings helped evacuate the New York City World Trade Center Tower stair cases during the 9/11 events. The NIST evacuation study results led to photoluminescent exit path marking requirements in NYC high rise office building staircases, and became an IBC/IFC Codes requirement and NFPA101-Life Safety Code.
