What does AFFF stand for?

AFFF stands for Aqueous Film-Forming Foam Concentrate. This term describes a specific type of firefighting foam that is effective for extinguishing flammable liquid fires. AFFF works by creating a film on the surface of the burning liquid, which helps to smother the flames and prevent the release of flammable vapors. The formulation is designed to enhance its ability to spread quickly over surfaces and to create a barrier that separates the fuel from the oxygen, thereby effectively suppressing the fire.

The term "Aqueous" refers to the water-based nature of the foam, while "Film-Forming" indicates its capability to form a film that aids in suppression. The inclusion of "Concentrate" denotes that this foam is typically mixed with water before it is applied in firefighting scenarios, making it essential for effective fire control methods in both fixed systems and portable firefighting applications. Understanding the components and functionality of AFFF is crucial for those in the fire safety and emergency response fields.
