ANSULITE 3% (AFC-3A) AFFF Concentrate is intended for use on Class B hydrocarbon fuel fires having low water solubility such as various crude oils, gasolines, diesel fuels, aviation fuels, etc. It is not suitable for use on fuels having appreciable water solubility (polar solvents), i.e., methyl and ethyl alcohol, acetone, and methyl ethyl ketone.
It can be used with both aspirating and non-aspirating discharge devices because of the low energy required to make it foam.Its excellent wetting characteristics make it useful in combating Class A
fires as well. It can be used with dry chemical extinguishing agents without regard to the order of application to provide even greater fire protection capability.
