Abstract
The present invention relates to a novel fire extinguishing composition comprising a unique salt mixture and a method of using the novel composition combination with water to extinguish Class B and Class C fires. The fire extinguishing composition comprises an unique mixture of at least two salts, I and II: wherein I is selected from the group consisting of a bicarbonate or carbonate salt of sodium or potassium and II is selected from the group consisting of a chloride, sulfate, or tartrate salt of sodium or potassium and wherein the mixture exhibits a single minimum melting point. It has been found that the composition when applied as a combination with water provides excellent results in extinguishing class B fires, especially those involving cooking appliances using a large quantity of oil or fat, such as deep fryers.
