WIPO Patent Application WO/2002/085460
Kind Code:
A1
Abstract:
A fire-extinguishing agent which, when used in extinguishing a fire, readily holds and solidifies water by the action of the heat of the fire and adheres to the burning object to thereby extinguish the fire or prevent the fire from spreading; water for fire extinguishing; and a method of fire extinguishing using the water for fire extinguishing. The fire-extinguishing agent comprises a temperature-sensitive polymer which is water-soluble at temperatures not higher than a specific set temperature and which, when heated to a temperature not lower than the set temperature, i.e., heated by the heat of a fire, holds water and causes the water to gel or solidify. The water for fire extinguishing comprises water and the fire-extinguishing agent dissolved therein and which optionally contains a flameproofing agent, other fire-extinguishing agent, and the like.
