<p>Flammable liquids are soaked up and rendered safe from ignition by mixing with the liquid a particulate composition containing an absorbent solid, a first high molecular weight polymer soluble in the flammable liquid, a dry chemical fire extinguishing agent and, optionallly, a second polymer which is not soluble in the flammable liquid but is soluble in water. The first polymer gels the flammable liquid and the solution of polymer and liquid serves to adhesively bind particles of absorbent solid together while the second polymer when wet with water forms a non-combustible film over all exposed surfaces.</p> |
