What is the chemical used in AFFF?

Aqueous Film Forming Foam (AFFF) is a fire suppression agent that relies on the unique properties of synthetic fluorocarbon surfactant materials to combat flammable liquid fires. The surfactants in AFFF create a film that can spread across the surface of flammable liquids, effectively smothering the flames and preventing vapor release. This film formation is essential for reducing the heat and preventing re-ignition, making AFFF highly effective in aviation and other firefighting scenarios.

The components of AFFF are specifically designed to provide rapid extinguishment and a thermal barrier, which distinguishes them from other fire-suppressing agents. Understanding the composition of AFFF is critical for those in aviation warfare, as using the most effective firefighting agents can save lives and equipment during emergencies. The other options do not represent the chemical makeup of AFFF, highlighting why the choice of synthetic fluorocarbon surfactant material is the correct answer.
