In the prevention of the spread of fires and for directly fighting fires, a cross~linked, water-swellable additive polymer in a vegetable oil dispersion is added to firefighting water. The additive has the properties of absorbing large quantities of water, high viscosity for adherence to vertical and horizontal surfaces, and retention of sufficient fluidity to be educted in standard firefighting equipment. The method of adding this additive to the firefighting water by eduction, pumping, or batch addition to the source water is also disclosed.

Selon la présente invention, dans la prévention de la propagation d'incendies et pour lutter directement contre les incendies, un polymère additif réticulé gonflant dans l'eau en dispersion dans une huile végétale est ajouté à l'eau d'extinction. L'additif a des propriétés d'absorption de grandes quantités d'eau, de viscosité élevée pour adhérer aux surfaces verticales et horizontales, et de conservation d'une fluidité suffisante pour être projeté par un équipement de lutte contre les incendies standard. Le procédé d'ajout de cet additif à l'eau d'extinction par échappement, pompage ou ajout discontinu à la source d'eau est également décrit.
