What does AFFF stand for in fire extinguisher terminology?

• A. Air Foam Fire Flow
• B. Aqueous Film Forming Foam
• C. Advanced Firefighter Foam
• D. Aromatic Fluid Fire Foam

Answer: (B)

AFFF stands for Aqueous Film Forming Foam, which is a type of fire suppressant designed specifically for use on flammable liquid fires like those involving gasoline, oil, and other hydrocarbons. This foam creates a barrier on the surface of the burning liquid, preventing re-ignition and effectively smothering the fire by cutting off the oxygen supply. This formulation is particularly effective because it not only helps extinguish flames but also forms a protective film that can suppress vapors, which are often the most hazardous element in flammable liquid fires. Aqueous Film Forming Foam works by using water mixed with specific chemicals to create a foam that can blanket and cool the fire, making it a preferred choice in many firefighting scenarios, especially in industrial and aviation settings. Understanding this term is fundamental for firefighters and safety personnel, as it highlights the importance of using the correct type of fire suppression methods based on the nature of the fire hazard.
