Abstract: Methods of extinguishing a fire in the presence of an alkali metal, such as lithium type fires, by contacting the fire with a mixture of different nonylphenolethoxylates with a non-aqueous solvent.
Abstract: 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, poly(oxy-1,2-ethanediyl), .alpha.-phenol-.omega.-hydroxy-(2)-phosphate to 3000 ppm surfactant and 141 ppm arylphosphate. The spray solution is applied to the fire until the desired result occurs.
