What does AFFF stand for in firefighting systems?

AFFF stands for Aqueous Film Forming Foam. This type of foam is specifically designed for firefighting purposes, particularly effective in combating flammable liquid fires, such as those involving petroleum products. The aqueous component provides a water-based solution, which is crucial in forming a film that spreads over the surface of the burning liquid. This film helps to suppress the fire by smothering it, reducing the release of flammable vapors, and cooling the fire through the water content.

This makes AFFF an essential agent in the firefighting arsenal, especially in industrial settings where the risk of flammable liquid fires is significant. The formulation allows for quick extinguishment and can be used in various delivery methods, either from sprinklers or portable extinguishers, thus providing versatility in firefighting operations.
