🔍 Key Concepts

• Classes of fire (Class A, B, C, D) and which types involve flammable liquids • How chemical foam works to smother a fire by forming a blanket over the fuel surface • Why water-based agents can be dangerous on energized electrical equipment

💭 Think About

• First, match each answer choice to the class of fire it represents (solid combustibles, flammable liquids, electrical, etc.). Which class is foam mainly designed for? • Think about how foam behaves: it spreads over a surface and cuts off oxygen. On which type of fuel does forming a surface blanket make the most sense? • Which choice, if chosen, might create extra risk if water or foam conducts electricity or fails to adhere well to the surface?

✅ Before You Answer

• Identify which choice represents a flammable liquid fire • Eliminate any options where using water or foam on energized electrical equipment could be hazardous • Consider whether foam can effectively coat and form a blanket over the burning surface in each option
