A battery powered, illuminated, color-coded evacuation signalling system embodying symbols and text messages in any language or combination of languages, configured by LED's in a network of floor laid display units installed in land-based buildings or maritime structures. The system induces automatic dissemination of walking or crawling evacuees during an emergency, particularly in smoke, fog and low-light conditions, by guiding them away from deemed danger zones, then along assessed safe routes leading towards assessed safe designated exits. LEDs shine through transparent covered, narrow strip assembly units laid in the center of walkways. Red denotes predetermined and developing ‘danger zones’. Green denotes safety ‘go-routes’. Amber indicates system status. In-going firefighters may access a time-identified schematic picture relating to the spread of fire, temperatures and air quality, to evaluate what areas of a structure are safe or unsafe to enter.
A color-coded evacuation signaling system wherein temperature and air-quality data is received from a network of smoke, heat, CO2, CO, toxic gas, combustible gas or related hazardous-element detectors, then processed by a power supply processor, being also a programmable interactive micro processing unit which accesses pre-programmed schematic data relative to the location of designated exits, and which evaluates said temperature and air-quality and schematic data for the purpose of illuminating direction-indicating symbols and text messages, displayed in any required language or combination of required languages, configured by light emitting diodes (LED's) contained in transparent-covered assembly units, connected in series to form a continuous strip or array laid flush in the center of uncovered or covered floors, corridors, walkways within land-based buildings and maritime structures, to guide walking or crawling evacuees who may find themselves in low-light conditions or in a smoke fog during a fire or general emergency, initially away from predetermined and assessed developing danger zones, represented by the color red, and then via assessed safe routes, represented by the color green, leading to their nearest and safest assessed designated exits, the color of respective illuminated assembly units being variable based on the location of danger zones.
A color-coded evacuation signalling system wherein a power supply processor being also a programmable, interactive micro processing unit, contains pre-programmed schematic and alpha-numeric data relating to the location of designated exits within land-based buildings and maritime structures;
