PRODUCTS FOR FIGHTING FIRES, SOLIDS WITH GASEOUS ADDITIVES TO FLOAT ON INFLAMMABLE LIQUIDS, USED IN FIGHTING FIRES WHILE ABLAZE
Document Type and Number:
WIPO Patent Application WO/1983/002235
Kind Code:
A1
Abstract:
Mixture of solids and gases, resulting in a product of low density which floats on inflammable liquids. In the case of fire, when used on the fire places itself between the fuel and the flame and separates one from the other. Since these are iced or cold they eliminate or reduce considerably the production of gases which emanate from the surface of the liquid and reduce the size of the fire. Since these are volatile at the temperature of the surface of the liquid in flame they produce a non-combustible cloud which suffocates the fire.

Description:
Descriptive report of patent of invention "PRODUCTS FOR FIGHTING FIRES, SOLIDS WITH ' GASEOUS ADDITIVES TO FLOAT ON INFLAMMABLE LIQUIDS, USED' IN FIGHTING FIRES WHILE ABLAZE". 5. This invention refers to solids' composed of fireproof products, with gaseous additives,' resulting in a unit of low density which floats on ' inflammable liquids, used to fight fires in fuel tanks.
For fighting fires, there may be
10. used, among others: water in the form of ice- or carbonic gas in the form of dry ice, both with gaseous additives.
The smaller the gaseous additives are, and the larger in number, uniformly distributed, the easier it will be to form a solid, 15. homogeneous mass of low density to use in fighting fire
These solids with gaseous additives when crushed do not lose their capacity of floating. Therefore, a larger surface of inflammable liquid can be covered with a smaller quantity. VJhen used 20. in sufficient quantity to the point of superimposition they form a thick spume capable of eliminating the evaporation of the fuel to the point of suffocating the fire.
