Best Mode for Carrying out the Invention Hereinbelow, a composition of a fire-extinguishing agent according to the present inventionwill be describedwith reference to the preferred embodiments. A fire-extinguishing agent composition according to the present invention is nonpoisonous, innoxious, transparent, liquefied, and flame-retarded. Also, the fire-extinguishing agent composition according to the present invention is not gelated, does not become non-transparent, and is not precipitated by chemical reaction between elements of the composition. Also, the fire-extinguishing agent composition according to the present invention does not react with ions due to additives such as a surface active agent and an antifreeze. The fire-extinguishing agent composition according to the present invention fire-extinguishes by isolating oxygen gases due to generation inert gas, formation of films, producing moisture. The fire-extinguishing agent composition according to the present invention can be obtained by dissolving: aluminum sulfate of 20-30 weight%; chromic potassium alum of 10-20 weight%; a combination of aluminum chloride of 10 weight% and magnesium chloride of 10 weight%; sodium bicarbonate of 10-20 weight%; or a combination of ammonium phosphate monobasic of 10 weight%, ammonium phosphate dibasic of 10 weight%, and urea of 10 weight% . The chemical structures of compositions to be synthesized according to embodiments of the present invention will follow. Aluminum sulfate (Al2(SO4)SXH2O) is an eighteen hydrate, has a solid of 18% or more, is a colorless crystal, is melted in water, the specific gravitythereof is 1.69 and the meltingpoint is 86.5°C, and the hydrogen ion concentration (pH) thereof is 3. As an embodiment of the present invention, aluminum sulfate of 10 weight% and chromic potassium alum of 10 weight% are dissolved in the distilled water. Here, a nonionized surface active agent of 0.5-1.0 weight% is added. Also, monoethyleneglycol (MEG) of 25 weight% or polypropyleneglycol (PPG) of 25 weight% is added so that the transparent liquefied composition is not frozen. Aluminum sulfate, aluminum chloride, sodiumbicarbonate, and ammonium phosphate which are dissolved in distilled water causes gelation and precipitation in the result of chemical reaction. Also, when an anion surface active agent or a cation surface active agent is added for the purpose of producingbubbles, gelation still exists in reaction, to accordingly cause a non-transparent liquefied phase composition. Accordingly, in this embodiment, as an example, aluminum sulfate of 10 weight% is dissolved in distilled water together with a non-ionized surface active agent of 0.5-1.0 weight% and an antifreeze of 25 weight% such as monoethyleneglycol (MEG) or polypropyleneglycol (PPG) , to thus obtain a transparent liquefied fire-extinguishing agent composition. Sodium bicarbonate and ammonium phosphate which are dissolved in distilled water also cause gelation in the result of chemical reaction. Accordingly, a non-ionized surface active agent of 0.5-1.0 weight% .and an antifreeze of 25 weight% such as monoethyleneglycol (MEG) or polypropyleneglycol (PPG) is dissolved in the distilled water in which sodium bicarbonate and ammonium phosphate are dissolved, to thus obtain a transparent liquefied fire-extinguishing agent composition. Ammonium phosphate monobasic is represented as a chemical formula NH4H2PO4 is odorless and colorless, is stable in the air, is melted in the water, and generates water and ammonia gas if it is heated up to 190"C or higher. Ammonium phosphate dibasic is represented as a chemical formula (NH4)2HPO4 is melted in the water and generates NH3 if it is heated up to 155°C to become ammonium hydrogenphosphate. As another embodiment, ammonium phosphate monobasic of 10 weight% is dissolved in the distilled water. Then, ammonium phosphate dibasic of 10 weight% is dissolved as an addictive. Also, urea (CO(NH2)2) of 10 weight% is dissolved as an addictive. Then, a non-ionized surface active agent of 0.5-1.0 weight% and an antifreeze of 25 weight% such as monoethyleneglycol (MEG) or polypropyleneglycol (PPG) is dissolved as additives. Urea is of the specific gravity of 1.335 and is colorless and thus transparent. If solution of urea is heated up to 132.7"C, ammonia and carbonic acid gas is slowly generated, to accordingly provide a- fire-extinguishing function at fire. As still another embodiment, aluminum chloride of 10 weight% andmagnesium chloride of 10 weight% is dissolved in distilledwater. Then, a non-ionized surface active agent of 0.5-1.0 weight% and an antifreeze of 25 weight% such as monoethyleneglycol (MEG) or polypropyleneglycol (PPG) is dissolved therein, to thus obtain a transparent liquefied composition. In more detail, examples of the intensified liquid fire-extinguishing agent composition according to the preferred embodiments will follow. Example 1 The fire-extinguishing agent composition includes distilled water of 54 weight%, aluminum sulfate of 20 weight%, a non-ionized surface active agent of 1 weight%, and an antifreeze of 25 weight% such as monoethyleneglycol (MEG) or polypropyleneglycol (PPG) .
