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

L'invention concerne un agencement permettant de sécuriser l'évacuation et le sauvetage, en cas de sollicitations dues à des fumées, des charges thermiques et polluantes, dans des espaces pourvus de longues voies de secours, tels que des exploitations minières, des installations de trafic souterraines, et analogues. A cet effet, ledit agencement exploite les propriétés d'un brouillard d'eau produit par des moyens utilisés, afin que l'air reste respirable pendant une longue période, au moins dans la zone située en dessous de la couche des gaz de fumée, et puisse être maintenu au moins clair, de sorte que le sens d'évacuation reste identifiable. Selon ladite invention, les buses de pulvérisation (3) produisant ledit brouillard d'eau, sont fixées le long d'arcs de pulvérisation (2) disposés sur toute la longueur de l'espace et/ou de ses voies de secours, les uns derrière les autres, perpendiculairement au sens d'évacuation, à la suite du profil d'espace libre de l'espace et/ou des voies de secours. Avec l'agencement en forme d'arcs des buses de pulvérisation (3) sur toute la longueur des espaces et des voies de secours, tout l'ouvrage d'art est divisé en sections, qui n'entravent pas le flux d'air (6) présent dans ledit ouvrage d'art, de sorte que le courant de fumée ou de substances nocives n'est pas retenu par le brouillard d'eau produit.
