Abstract
In the prevention of the spread of fires and for directly fighting fires, a cross-linked, water-swellable additive polymer in a vegetable oil dispersion is added to firefighting water. The additive has the properties of absorbing large quantities of water, high viscosity for adherence to vertical and horizontal surfaces, and retention of sufficient fluidity to be educted in standard firefighting equipment. The method of adding this additive to the firefighting water by eduction, pumping, or batch addition to the source water is also disclosed.
