Abstract

L'invention concerne un procédé et un dispositif de lutte contre l'incendie spécifique à un volume et/ou une surface avec des agents d'extinction dans des zones de bâtiments ou d'installations menacées par un incendie. L'invention a pour but d'améliorer des installations physiques de telle manière que la charge thermique en cas d'incendie ne puisse pas s'étendre à d'autres zones et que des issues de secours, des passages, des ouvertures dans des cloisons et l'équipement technique garé tel que des appareils de commande, des chariots élévateurs, etc. soient largement protégés de l'influence de l'agent d'extinction en réduisant davantage la consommation d'agent d'extinction et en réduisant les dommages en cas d'incendie tout en augmentant la rentabilité, une compensation architectonique étant en même temps obtenue entre l'ouvrage et l'installation d'extinction. Ce but est atteint du fait que, autour du foyer d'incendie et/ou dans la zone menacée par l'incendie, un mur d'agent d'extinction composé d'un brouillard de fines gouttelettes destiné à éviter qu'une charge thermique s'étende dans d'autres zones est produit le long d'au moins un plan de pulvérisation vertical et/ou horizontal étendu entre les supports faisant partie du foyer d'incendie ou de la zone menacée par l'incendie et surveillé par les moyens de détection et/ou en même temps un autre mur d'agent d'extinction composé d'un brouillard de fines gouttelettes destiné à protéger et refroidir des issues de secours, des passages ou des voies de déplacement, des ouvertures dans des cloisons coupe-feu et un équipement technique à l'intérieur de l'ouvrage est produit le long du plan de pulvérisation étendu entre ces supports verticaux associés conducteurs d'agent d'extinction.
