Abstract

L'invention porte sur une produit d'extinction agissant sur différents types de feux tout d'abord par la production de mousse isolant le foyer de l'oxygène de l'air, et secondairement par diffusion d'un gaz liquéfié incombustible présent dans la mousse, qui s'en dégage lorsqu'elle éclate et en renforce le pouvoir extincteur. Ledit produit s'obtient en remplissant un récipient d'une solution aqueuse à 6 à 20 % en volume d'un agent générateur de mousse et du susdit gaz liquéfié, sous une pression de 30 kg/cm2.
