This one-hour course examines the need for photoluminescent lighting systems in stairways of buildings across the country to provide a safe pathway of exit during emergencies. The idea of finding a way to illuminate a safe path for building occupants has been tossed around for decades, but the main obstacle encountered in the past has been the way to do so consistently without electricity. So, the evolution of photoluminescent egress lighting will be discussed as well as new advances in technology that now permit occupants to find a safe route even without electricity. Current code and testing methods will be reviewed that now mandate the implementation of photoluminescent systems that not only light the way but also provide information about the building in terms of location and items that may be used in cases of emergencies. The types of luminescent products will be presented as well as the benefits of using photoluminescent products inside buildings to better protect building occupants.
