The fire fighting and hot surface cooling methods of this invention use a composition formed by combining a nonionic surfactant possessing a specific photoexcitable functional group with an arylphosphate, also of photoexcitable nature, in a solvent medium of composition and content that allows for a convenient workable viscosity and is resistant to effects of freezing. The ultimate water solution used for spraying to extinguish a fire or cool a surface contains from 2000 ppm of the surfactant nonylphenolethoxylate and 94 ppm of the arylphosphate, phenol-6-phosphate, to 3000 ppm surfactant and 141 ppm arylphosphate. A non-aqueous composition containing a mixture of different nonylphenolethoxylates to extinguish lithium type fires is also described. The spray solution is applied to the fire until the desired result occurs.

Les méthodes d'extinction d'incendies et de refroidissement de surfaces chaudes de la présente invention utilisent une composition formée par combinaison d'un surfactif non ionique renfermant un groupe fonctionnel spécifique photoexcitable, avec un arylphosphate, également de type photoexcitable, dans un solvant dont la composition et la teneur donnent une viscosité se prêtant au traitement, et qui résiste aux effets de la congélation. La solution d'eau finale, pulvérisée sur un feu pour l'éteindre ou sur une surface pour la refroidir, renferme de 2000 à 3000 ppm du surfactif nonylphénoléthoxylate et de 94 à 141 ppm d'arylphosphate, soit le phénol-6-phosphate. L'invention décrit également une composition non aqueuse renfermant un mélange de différents nonylphénoléthoxylates pour éteindre des incendies de type au lithium. La solution est pulvérisée sur le feu jusqu'à obtention du résultat recherché.
