Abstract: A fire extinguishing equipment for extinguishing cooking oil fires includes fire extinguishing agent, a single-layer hot-melt resin film enclosing the fire extinguishing agent, at least one float, and a quadratic prism-shaped paper case enclosing the single-layer hot-melt adhesive film and the at least one float. The quadratic prism-shaped paper case includes a plurality of sides, at least one of which has al least one outlet.

Abstract: The present invention provides a resin laminated film for enclosing fire extinguishing agent, comprising a plurality of hot-melt resin films which are laminated at least two layers in the order of highest melting point to lowest melting point from the side that contacts frying oil, and further provides a fire extinguishing equipment which can be directly thrown into the cooking utensils in case of frying oil fire utilizing the said resin laminated film.

Abstract: A process is provided for producing an extinguishing agent. Sodium chloride and ammonium dihydrogenphosphate are dissolved in hot water at a temperature of 30 to 40° C. to form a solution. Ammonium hydrogen carbonate is dissolved into the solution, and allowed to undergo a reaction with the ammonium dihydrogenphosphate, as dissolved. The sodium chloride is present in the extinguishing agent in a ratio of 5 to 15 g per 500 ml of water, the ammonium dihydrogenphosphate is present in the extinguishing agent in a ratio of 50 to 70 g per 500 ml of water, and ammonium hydrogen carbonate is present in the extinguishing agent in a ratio of 50 to 70 g per 500 ml of water. Also provided is a process of producing a throw-type fire extinguisher.

Abstract: The purpose of the present invention is to provide the method of preventing the expansion at a minimum and extinguishing oil fire easily and to provide an extinguisher. The method of extinguishing oil fire which occurs in cooking equipment for household use or for business use is to spray extinguishing agent to firing cooking equipment as consecutive liquid drops at the flow rate from 20 ml/min to 1200 ml/min per one excretory pore at the height from 0 cm to 300 cm.
