Abstract

L'invention concerne une composition d'extinction renfermant: un sel qui peut être de l'acétate de potassium, du bicarbonate de potassium, du bicarbonate de lithium, ou du bicarbonate de sodium; un composé contenant du bore; et de l'eau. Cette composition d'extinction n'attaque pas les métaux, présente un pH approprié, et se révèle particulièrement efficace contre les feux d'hydrocarbures.
