AER-O-LITE AFFF is a synthetic foam-forming liquid designed for use with fresh, sea or brackish water. When proportioned with water and applied with conventional foam or water/fog equipment, it generates a white foam with the remarkable ability to make water float on flammable liquids which are lighter than water.
This double action — foam and aqueous film — enhances extinguishment of flammable liquid fires and prevents reflash. The action also takes place on spilled or leaking fuels, which have not been ignited so they are secured and are not readily ignited.
AER-O-LITE AFFF can be used with conventional foam equipment. Foam nozzles with pick-up tubes and line proportioners (in-line eductors) used with foam or water/fog nozzles are among the most common methods.
Unlike ordinary foams, 1st Defense AFFF may be used effectively with the water/fog nozzle and eductor combination and keep it extinguished. The foam spreads over the surface of burning fuel forming a blanket in the manner of conventional foams. More important, an aqueous solution drains from the foam bubbles and forms a vapor-sealing film. This film floats on the fuel surface and suppresses volatile vapors. In addition, it has a reforming, self-healing action, which prevents reflash should the foam be disrupted.
