In the last decade there have been many advances in foam for firefighting. Since 2001 the multinational 3M ceased to manufacture surfactants and fluorinated AFFF foams due to the ban on PFOS (perfluorooctyl sulfonates), a flurry of development has been carried out by manufacturers of fluorinated derivatives and foams.
The ban of PFOS required by an European and American Regulations, the decreasing of chains length (from 8 to 6 carbon atoms) in the fluorinated materials to reduce precursors of PFOA, the different proposals to limit the PFOA levels or even the regulation on the use of halogenated organic compounds in some countries have made the market of foams for firefighting very dynamic with changes on legislation, development of new products, etc. in the last decade. The fluorine-free foams (Fluorine Free, 3F, FFF) have become very important in recent times, in some cases even as substitutes for AFFF agents, being the subject matter of controversy and discussion in all international forums.
