These are the basic essentials used by leading testing laboratories such as UL and the federal government. This is the accepted test norm to assess the foam liquid's value. Note, controlled tests are conducted, not demonstrations. On a comparatively smaller scale, airport firefighters can encounter polar solvents in maintenance facilities. Although underground tanks store the fuel, deliveries are received by tank truck and vehicles operate in and about the airport.
Accidents can and do occur.
AFFF, federally or commercially formulated, have demonstrated their inability to extinguish such fires. The intense temperature generated by the polar solvent fires overwhelm the poor heat resistant AFFF and fail. These foams, however, must never be mixed with any other type of foam liquid concentrate. Foams made exclusively for hydrocarbon fuels are totally ineffective on polar solvents. Prior to their use, you should consult the listing of approval agency for details of the approval.
