Glow in the Dark Exit Signs- 4 Things You Need to Know
Glow in the dark exit signs have grown in popularity throughout the past few decades. Also known as photoluminescent exit signs, they are both efficient and effective for new buildings and those updating. Not only are they one of the most sustainable options for exit signs, but UL924 photoluminescent exit signs meet requirements set forth by OSHA, IBC, IFC, and NFPA 101. More counties, cities, and states are updating their laws to now require the use of glow in the dark exit signs for these reasons and more.
Understanding Glow in the Dark Exit Signs
Glow in the dark exit signs are a straightforward technology, easy to install, and maintain. Whether you are looking to update your old emergency exit signs or have new construction, consider these 4 facts about photoluminescent exit signs.
- They are extremely eco-friendly
It’s no surprise the US Department of Energy came out saying that glow in the dark exit signs are the most energy-efficient exit sign on the market. Requiring no electricity and 100% recyclable, even the EPA (Environmental Protection Agency) approve photoluminescent exit signs and egress systems, working to pass legislation to make the use of it mandatory in several states.
If you are a builder, you can also earn points towards LEED certification (Leadership in Energy and Environmental Design). LEED is the most commonly used green building rating system in the world and photoluminescent technology is extremely eco-friendly, fitting right into their framework.
- Phosphor is the main material used
Phosphor is an element found in the Earth that has the ability to absorb, store, and emit light at a later time when exposed to light beforehand. This makes them an excellent material choice for anything that needs to glow in the dark, including emergency exit signs.
The stored energy that these exit signs take in with the phosphor is then stored and gradually released. This produces a high illumination that fades over a long period of time (upwards of over 18 hours!). Long-persistence phosphor (LPP) is what the process is called when emitting light for a much longer period of time. Consider your exit sign like a sponge soaking up and holding light energy and then slowly releasing it. That friends, is a process called phosphorescence.
- Maintenance costs are minimal
Technology aside, the maintenance is simple. Unlike an electric exit sign that is illuminated through light bulbs that will need to be replaced over time, there are no bulbs to replace with glow in the dark exit signs. The typical maintenance is verifying that light is in operation and wiping off dust with a damp cloth occasionally. And did we mention once they are installed you can easily keep them operational for 25+ years?
- Make sure they meet compliance
Like any emergency exit sign you will want to make sure the photoluminescent exit signs you are purchasing are compliant and installed with NFPA 101, International Building Code, and the International Fire Code specifications. Also, the Underwriters Laboratories (UL) and your local jurisdiction will usually have requirements that you will need to be aware of. Make sure the exit signs meet all the criteria in place for placement, illumination, sizing, etc. set forth by all these organizations to ensure complete compliance and prevent the possibility of fines.
More Than Just Glow in the Dark Exit Signs
Photoluminescent products go way beyond exit signs. You will also be able to find glow in the dark egress path markings and other fire safety signage to put you in total compliance while being electricity free.
