What type of fire is a FFFP extinguisher effective against?

• A. Class A fires only
• B. Class B and C fires
• C. Metal fires
• D. Class K fires (kitchen grease)

Answer: (B)

The effectiveness of a FFFP (Film-Forming Fluoroprotein) extinguisher lies in its ability to combat Class B and Class C fires. Class B fires involve flammable liquids such as gasoline, oil, and grease, where the extinguisher works by creating a barrier that prevents oxygen from reaching the fuel. This is accomplished by forming a film that smothers the fire, making it particularly effective against liquid fuels that float on water. Additionally, Class C fires involve energized electrical equipment. FFFP extinguishers are suitable for this category because they are non-conductive and can safely be used on live electrical fires. This versatility makes FFFP extinguishers a valuable tool in various firefighting scenarios, particularly where flammable liquids and electrical risks are co-located, such as in a maintenance shop or manufacturing facility. Other fire classes mentioned, such as Class A (ordinary combustibles like wood and paper), metal fires, and Class K (cooking oils and fats), fall outside the primary effectiveness of a FFFP extinguisher. Class A fires generally require water or foam extinguishers, metal fires need specialized agents due to their unique properties, and Class K fires are best addressed with wet chemical extingu
