The installation of Photoluminescent Material (*PLM) Way Guidance Systems along evacuation routes is rapidly gaining international acceptance and support as a secure and defined means of improving occupants fire safety in the event of ANY emergency situation. A *PLM system consists of signage elements that can be installed in the form of signs, paint, strips or fabric on any surface. The particularity of this non-radioactive material is that it contains pigments which have the capacity to store, in a few minutes, the energy from normal lighting.
