AFFF stands for Aqueous Film Forming Foam. It is a type of firefighting foam that is primarily used for suppressing flammable liquid fires. The foam forms a film on the surface of the burning liquid, which helps to smother the fire and prevent the release of flammable vapors. This is a significant feature that enhances its effectiveness compared to other types of firefighting foams.

AFFF is particularly useful in situations where hydrocarbons or polar solvents are involved since it can create a barrier that reduces the risk of re-ignition and allows for faster extinguishment of the fire. Its ability to spread quickly over liquid surfaces makes it a critical tool in many firefighting scenarios, especially in aviation and industrial applications.

The other options listed do not accurately reflect the characteristics or composition of AFFF, which is specifically designed for fire suppression through the formation of an aqueous film.
