If the question has a related picture, it will appear here.

🔍 Key Concepts

• Fire classes and what materials they represent (A, B, C, D) • How foam works to extinguish fires (smothering and separating fuel from oxygen) • Which fire classes involve flammable liquids vs electrical equipment or metals

💭 Think About

• First, match each fire class (A, B, C, D) with the type of material burning. Which one is flammable liquids like oil, gasoline, or paint? • Think about how foam is applied on a liquid surface. Which type of fire would benefit from forming a blanket over the fuel? • For each class, ask: would foam be safe and effective here, or could it conduct electricity or react dangerously with the burning material?

✅ Before You Answer

• Be sure you know that Class C involves energized electrical equipment—consider whether water‑based foam is appropriate around electricity. • Remember that Class D involves combustible metals—check if standard foam is recommended or if special agents are needed. • Confirm which class is specifically defined as flammable liquids and flammable gases and ask yourself if foam is commonly used on those.
