AFFF is Aqueous Film Forming Foam
A Class A, B, C, or ABC fire extinguisher works wonders on several different types of fires. A is good for wood, paper, etc. B is good for liquids. C is good for electrical fires. Do not use a Class D, for these are best on metals (such as magnesium).
aqueous film forming foam (AFFF), if you have one, although CO2 or dry-chemical fire extinguishers are also rated for combustible liquids, such as diesel.
Foam fire extinguishers are used mainly for flammable liquid fires and are mostly used by professionals and in commercial and industrial settings. These extinguishers are charged with anther AFFF, FFFP, or AR-AFFF, however, these class of extinguishers are only rated class A & B fires and are hazardous to the environment, humans and animals in addition to being very corrosive.
fire extinguisher safety training Topic: Question Summary: Do I have to take a fire extinguisher class? Question Long-Form: I own a fire extinguisher. Am I required to take fire extinguisher training? If so, where are they offered?
Water, foam concentrate, and air.
"foam" fire extinguishers are made for hydrocarbon fires...i.e: gasoline, diesel, etc. These fires are considered class "b" (flammable liquids), and are mostly used by professionals and in commercial and industrial settings. These extinguishers are charged with anther AFFF, FFFP, or AR-AFFF, however, these class of extinguishers are only rated class A & B fires and are hazardous to the environment, humans and animals in addition to being very corrosive.

AFFF stands for Aqueous Film-Forming Foam. It is used by fire fighters for the suppression of a fire where fuel is involved. It does this by coating the fuel and preventing oxygen enabling combustion.
AFFF stands for Aqueous Film-Forming Foam. It is a type of firefighting foam used to suppress fires by creating a film on the fuel surface, preventing the release of flammable vapors. AFFF is commonly used for combating fires involving flammable liquids, such as gasoline or jet fuel.
I wouldn't agree that afff is good for fire fighting. Perhaps at one time it was, before there were more cost effective and environmentally friendly options on the market. There are now wetting agents such as Novacool UEF (Universal Extinguishing Foam) that are a much better option. This foam, which is UL listed and certified under NFPA 18, is used at 1/6 to 1/12 of the concentration of AFFF and is bio-degradable. AFFF is most effective in a contained pool of Class B flammables but is not effective on 3 dimensional fires where Novacool UEF is. AFFF is outdated technology and needs to be replaced by modern day technology.
Using the American system for classification, here's the general type of extinguisher used:A (combustible materials) - water, AFFF (aqueous fire fighting film), dry chemicalB (flammable liquid or gas) - NEVER water. Dry chemical, AFFF, Halon, CO2C (electrical fires) - NEVER water. Dry chemical, Halon, CO2D (flammable metals) - NEVER water. Dry POWDER (not dry chemical) such as sodium chloride granules, graphite or copper.
