ABSTRACT:
A shaped body or an aggregation of a plurality of shaped bodies, e.g. pellets, comprising a solid, coalesced mixture of water soluble fluoroaliphatic surfactant and water soluble fluorine-free surfactant is contacted with a flowing stream of a predetermined amount of water, e.g., from the tank of a hand portable fire extinguisher, to produce an aqueous film-forming foam solution of relatively constant composition which can be applied to extinguish a fire or a flammable liquid.
