Photoluminescent Egress More Than Just Glowing Light -  Blog Image

The glowing green stars and half-moons in your childhood bedroom seem like just a happy memory. But Photoluminescent materials have become a huge part in the fire and life safety industry. Photoluminescent egress path marking systems are used to create an outline of steps, landings, handrails and any other pathways to help people escape from dark places during an emergency. While Photoluminescent objects seems fun and exciting in the dark, it is more than just glowing green light.


What Is Photoluminescent Light?

Luminous simply means giving off light. Photoluminescence (PL) is light emission from any form of matter after the absorption of photons. So, when light is shined on a Photoluminescent object, the photons from the light excite the phosphorous molecules. These molecules then slowly release energy that has been stored by re-emitting photons, and creating the recognizable green glow. Therefore, Photoluminescent objects use sunlight, or recycle existing electrical light, to create a glow for continual visual light support.  A Photoluminescent prepared building increases the chance of its occupants surviving an emergency.

This is important in the event of a fire, where hallways and stairwells can quickly fill with smoke and become very dark and hard to see. Since smoke rises, the Photoluminescent marking along the floor can help guide people to a safe exit.  Because of this, more buildings today are being required by building codes to have Photoluminescent egress path marking systems and exit signs installed.

According to the 2009 International Building Code (IBC) and International Fire Code (IFC), “buildings having floors occupied more than 75 feet above the lowest level of fire department vehicle must be provided with luminous egress path markings”.


Why Photoluminescent Egress Marking Systems & Exit Signage?

There is nothing worse than being trapped in a building during a fire. And often times there is little to no warning that a fire has started. That’s why it is extremely important to make sure that all of your fire and life safety protection features are working and up-to-date with the codes. This also means making sure the proper egress is provided, including egress signs! Smoke rises, which can cause occupants to become disorientated and cloud their vision, making trips and falls  more likely to occur. The use of Photoluminescent strips create an outline of steps, landings, handrails and any other obstacles that could potentially cause someone to have an accident, while exit signs mark the quickest and safest way to evacuate.
