Abstract
A method and formulation are provided which are effective for fighting coal fueled fires. The composition puts out the fire, penetrates the burning coal, disperses fire gases, and does not generate any gases that are toxic to humans. The basic formulation comprises a linear alkylbenzolyate sulfonate, non-ionic detergent and lauric superamide detergent mixture comprising about 50% by volume of the formulation, vitamin B-6 in the amount of about 0.5-3% by weight of the detergent mixture, bicarbonate of soda in the amount of about 3-18% by weight of the detergent mixture, red vegetable color in the amount of about 0.25-0.75% by weight of the detergent mixture, eucalyptus oil (if present) in the amount of about 1-2% by weight of the detergent mixture, and water comprising about 37-47% percent by volume of the total formulation. Once the fire has been extinguished, a light is directed to the extinguished area, and red colored light will be reflected off of the extinguished area indicating that it is safe to proceed. The liquid formulation also may be used in a method of absorbing methane and other gases generated by a coal burning fire, or in a method of of retarding spontaneous ignition of coal by spraying it directly onto the coal.
