Floor Number signs Glow in dark

Glow-in-the-dark floor number signs, also called photoluminescent floor identification signs, are required in many high-rise and commercial buildings to ensure occupant safety during emergencies. These signs absorb natural or artificial light and then emit a bright glow in total darkness, helping residents, visitors, and firefighters quickly identify the correct floor in low-visibility conditions caused by smoke or power outages. By providing clear floor markings that remain visible without electricity, these signs support safe evacuation and rapid emergency response.

A glow floor number sign is typically mounted at each stairwell landing and corridor, marking the floor level and often including directional information for exits and stairwells. Common examples are “Floor 1,” “Floor 2,” “B1 Basement,” “PH Penthouse” signs in luminous materials. Photoluminescent floor number signs are mandated in many jurisdictions by FDNY, NFPA, IBC, and local building codes for high-rise egress systems. Installing these durable, maintenance-free signs ensures compliance with fire safety standards while enhancing life safety for all occupants.
