The present invention relates to improved methods of extinguishing fires or retarding fire propagation by forming a crosslinked water gel which is then applied to the fire or area to be protected. By forming a semi-solid crosslinked gel water can be conveyed over large distances while minimizing losses due to misting, thus making fire fighting from great distances possible and improving the efficiency of aerial drops. The crosslinked gel also has a particularly good adhesiveness and cohesiveness, giving it the ability to form one continuous blanket on the ground thereby smothering the fire and preventing re-ignition. The combination of these properties makes the crosslinked gel ideal for applications such as control and extinguishing of forest fires. In addition, the composition may include additional active ingredients such as herbicide, pesticide, fungicide fertilizer, or the like for soil remediation after the fire is extinguished. |
