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AFFF is outdated technology and needs to be replaced by modern day technology.

Which type of fire extinguisher should be used on an oil fire?
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).
Which gas helps the foam that fire fighters use?
In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution. Larger systems use a dedicated air compressor and compresses regular air from the atmosphere.Smaller systems can use any inert compressed gas such as Carbon Dioxide (CO2), Compressed Nitrogen (N2) or smaller tanks of compressed regular air.The simplest, most efficient and least expensive way of producing foam is with a portable foam eductor. These foam systems use regular hand lines and an eductuor 100 feet from the end of the nozzle. The eductor siphons foam solution from a tank or drum using the "Venturi" principal. When the foam solution reaches a standard fog nozzle, water pressure and the broken stream produced by the nozzle introduce air into the foam solution.There are other forms of nozzles that introduce water using the "Venturi" effect that are not user adjustable like a fog nozzle.The quick easy answer is regular air is used most commonly in fire fighting foam however CO2 and N2 can be used depending on the design of the system used.In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution.
