Abstract
The invention is directed to a system which allows for the rapid application of a water immobilizing dispersion in sufficient quantities to increase the fire protective and wetting characteristics of water. This system also increases the evaporative cooling and quenching effects of water. The primary constituents of the composition of this system are water, purified Attapulgite clay, and an environmentally safe salt, e.g., magnesium sulfate.
Claims10
A composition useful for providing a fire protective coating on surfaces by immobilizing water therein and producing evaporative cooling consisting essentially of about 5–15% Attapulgite clay, about 1–10% magnesium sulfate with water to make 100%.
A method for preventing the advance of a fire and creating a fire-barrier comprising applying to the area to be protected from the advancing fire a fire-barrier composition consisting essentially of fire-barrier effective amounts of a composition of Attapulgite clay, Epsom salt and water.
A method for fighting a fire consisting essentially of applying to said fire a composition of Attapulgite clay, Epsom salt and water in amounts effective to fight said fire.
