Self-luminous egress components are the most energy efficient compliance products since they do not require electricity to be visible. These identifiers are illuminated by either Tritium or photoluminescence and allow building owners to implement a dependable evacuation aid capable of helping occupants reach an egress point in the worst emergency conditions. Tritium exit signs are frequently installed as a zero-energy solution; however, they have certain characteristics that make them less ideal for use. Signs using this form of illumination contain a radioactive gas housed in a phosphor coated tube. While completely safe within the tube, the possibility of a breakage releasing this gas into the atmosphere generates environmental and health concerns. The risks associated with a breakage results in increased workload requirements to ensure occupant safety in a structure. Improper disposal, tube breakages, and lost signs can result in the gas being released into the atmosphere. Local building code compliance regulations recommend the implementation of photoluminescent exit signs for improved occupant safety.
How Are Photoluminescent Exit Signs Different?
Photoluminescence is a newer technology in the signing industry, but has been a common method of creating items such as glow-in-the-dark toys for many years. Tritium identifiers generate illumination as the housed gas reacts with the phosphor coated tube during beta decay. Photoluminescence involves the absorption of light photons, which are then either released immediately in the same form or over an extended period of time in an altered low level energy state. The process allows illumination to be provided without the use of toxic materials. Photoluminescent exit signs consist of a film and special pigment capable of storing energy until lighting conditions change. The photons are absorbed from surrounding light sources and then released in a matter of hours as a building becomes dark or smoke-filled. Owners making this choice do not have to follow special regulations set by the Nuclear Regulatory Commission (NRC) or pay extensive disposal costs when an identifier must be replaced.
What Advantages Are Supplied By Photoluminescence?
Photoluminescent exit signs offer several benefits over Tritium exit signs throughout their use. Owners are able to reduce compliance costs, decrease energy use, and provide a safer visual aid to occupants with this type of signing. The elimination of toxic materials makes the disposal process easier and more affordable. A photoluminescent exit sign is completely recyclable meaning no waste is added to a landfill. They last for approximately twenty five years with minimal maintenance requirements. Photoluminescence supplies a solid zero-energy solution where wiring, bulb changes, and backup power sources are not necessary. They also provide a suitable self-luminous alternative for avoiding the hazards of Tritium exit signs. Photoluminescence delivers these specific advantages:
• Highly Visible
• Low Maintenance
• Easy to Install
The choice to install photoluminescent identifiers in a structure ensures occupants will be able to find their way out in any type of emergency situation. These identifiers remove the troublesome expenses of traditional incandescent options without adding the risk of occupant exposure to radioactive materials. Photoluminescent exit signs are the most cost effective choice available to owners desiring a dependable, zero-energy solution.
