Firefighting foams are specialized substances used to extinguish fires, particularly those involving flammable liquids like gasoline or oil. These foams work by creating a barrier that smothers the fire, cutting off its oxygen supply and cooling the flames. They are often used in industrial settings, airports, and during wildfires. There are different types of firefighting foams, including Aqueous Film-Forming Foam (AFFF) and Protein Foam. Each type has unique properties suited for specific fire scenarios. Firefighting foams are typically applied using hoses or specialized equipment to ensure effective coverage and rapid fire suppression.
