SYSTEM FOR ENSURING EVACUATION AND RESCUE FROM THE EFFECTS OF SMOKE, HEAT AND POLLUTANTS

摘要

The invention relates to a system for ensuring evacuation and rescue from theeffects of smoke, heat and pollutants in areas with long evacuation routes,such as mining installations, underground transport systems, or similar. Saidsystem takes advantage of the characteristics of a mist of water, which isgenerated by misting means, in such a way that the air lying in the area belowthe layer of fumes can be respired for a long period of time and its claritycan at least be maintained, so that the direction of evacuation remainsvisible. According to the invention, the sprinkler nozzles (3), which generatethe mist, are fixed to sprinkler arches (2) that are positioned along theentire length of the area and/or its evacuation routes, one behind the other,transversally to the direction of evacuation, following the clearance contoursof the area and/or the evacuation routes. The arch-type arrangement of thesprinkler nozzles (3) over the entire length of the areas and evacuationroutes divides the structural installations into sections, which do not impedethe basic air flow (6) present in the installation, in such a way that thesmoke or pollutant flow is not accumulated by the mist that is produced.
