When it comes to public buildings, most people think of exit signs as a simple way to navigate the space, especially when they’re new to the building. In fact, many of us may never even glance up at the exit signs. In most situations, it’s easy to find our way out. In emergency situations, however, exit signs are a vital tool for evacuation. They help us find the quickest and simplest way to safety. When power is cut off or there is smoke present, illuminated exit signs are essential for everyone’s safety. Even those who use the building on a daily basis may lose their bearings when an emergency strikes. Photoluminescent exit signs are one excellent choice when choosing building safety signage. These self-luminous exit signs are an ideal way to guide occupants and visitors out of a building, especially in the absence of power or in the presence of smoke. In fact, photoluminescent exit signs are so dependable, they’re now required by safety codes in many cities to increase building safety as part of an egress lighting system.
Photoluminescent exit signs are non-electrical, glow-in-the-dark exit signs. They work just like a glow-in-the-dark key chain or sticker. Photoluminescent exit signs are coated in a chemical that absorbs the light from ambient lighting in their vicinity and, when power is lost or the lights are turned out, they radiate this light and continue to glow. Photoluminescent exit signs are a perfect building safety choice for two reasons. One, they are energy efficient. Because they use no electricity, they lower energy costs and conserve resources. Two, they are extremely dependable in an emergency. They continue to provide light even when back up emergency power systems fail - and they’re bright enough to be seen through smoke. Photoluminescent exit signs are non-toxic, non-radioactive, and come in a variety of viewing distances. The pigments used on most photoluminescent exit signs will glow for up to 8 hours in the absence of ambient lighting. The chemical coating will generally continue to glow in the dark for up to fifteen years, and they’re nearly effortless to maintain.
Recent studies have shown that photoluminescent exit signs decreased evacuation times in emergencies, especially when there is smoke present. New York City now requires photoluminescent exit signs in all public buildings, and many building safety experts believe that, had photoluminescent exit signs been present during the emergency evacuations of the World Trade Center, more people would have made it to safety. Cost of addingGreenTORCH™ Non-Electrical exit signs in a new building is dramatically reduced compared to an average of $500 per sign installation labor and parts for typical signs.
