What does AFFF stand for?

AFFF stands for Aqueous Film Forming Foam. This specialized type of fire-fighting foam is designed to suppress flammable liquid fires, such as those involving petroleum products. AFFF works by creating a film that quickly spreads over the surface of the burning liquid, forming a barrier that suffocates the fire by sealing off the fuel from oxygen. This ability to form a blanket not only helps to quickly extinguish flames but also prevents re-ignition after the fire has been suppressed.

Understanding the function and composition of AFFF is critical in fire safety and emergency response scenarios, particularly in environments where flammable liquids are present, such as airports, refineries, and chemical processing facilities. The correct designation of AFFF as Aqueous Film Forming Foam highlights its chemical properties and its use in effective fire suppression strategies, distinguishing it from other types of foams that may not provide the same level of efficiency or effectiveness in tackling flammable liquid fires.
