IBC and IFC codes require that buildings that have floors that are located more than 75 feet above the lowest level of a fire department vehicle must have luminous egress path markings in place that outline exit paths. Whether your facility falls under these code requirements or not, photoluminescent (or "PL") egress markers and signage are an excellent choice for outlining exit paths within facilities for several reasons.
PL markers are designed to charge, illuminate, and recharge without electricity, they simply need access to natural or artificial light. They can be used repeatedly without losing their performance quality and can last decades while requiring little maintenance over years of use.
PL egress markers are non-toxic, non-radioactive, and depending on your facility, using PL marking systems could qualify your building for LEED credits.
PL egress markers are designed to illuminate instantly when light systems fail during a fire or smoke emergency, making them a fast-acting and reliable system for leading people to safety during an emergency.
