Abstract: A method for rapidly cooling heated surfaces by spraying a low volume liquid stream without foam onto a heated surface which not only conserves the volume of fluid used, but also more quickly cools the heated surface compared to conventionally used water systems. The method of this invention uses a composition formed from a concentrate comprising one or more nonionic surfactants having a combined cloud point of 68.degree. F.-212.degree. F. and sufficient water to form a concentrate solution of not greater than 30% by weight of the surfactant. The ultimate heated surface cooling composition is formed from the concentrate to be passed through a conventional pump with not greater than 0.2% by volume of the surfactant in order not to cause undesirable foaming or cavitation of the pump due to the low concentration of the surfactant.

Abstract: A fire fighting composition and method for spraying a low volume liquid stream without foam onto a fire that conserves the volume of fluid used and yet more quickly snuffs out the fire. The fire fighting composition is formed from a concentrate comprising one or more nonionic surfactants having a combined cloud point of 68.degree. F.-212.degree. F. and sufficient water to form a concentrate solution of not greater than 30% by weight of the surfactant. The ultimate fire fighting composition is formed from the concentrate and passed through a conventional pump. A fire fighting solution is formed having not greater than 0.2% by volume of the surfactant that does not cause undesirable foaming or cavitation of the pump due to the low concentration of the surfactant. The fire fighting solution in this form is sprayed onto fires to form an effective means for combatting fires while achieving high versatility for conventional fire fighting pumping apparatus.
