🔍 Key Concepts
• Fire class categories and what type of material each class covers
• Where metal fires (like magnesium, sodium, potassium) fall in the fire classification system
• What typical extinguishing agents are used for metal fires compared with ordinary combustibles, flammable liquids, and electrical fires
💭 Think About
• First, identify what kind of material magnesium is and whether it is an ordinary combustible, flammable liquid, electrical equipment, or a special hazard
• Think about which type of fires require special dry powder agents instead of water, foam, or CO₂
• Recall which fire class is specifically reserved for combustible metals rather than paper, fuel, or electrical equipment
✅ Before You Answer
• Match each option (A–D) to its correct material type (ordinary combustibles, flammable liquids, electrical equipment, combustible metals) before deciding
• Make sure you are not confusing electrical fires with metal fires—they are different classes
• Verify which class of fire is described in your study materials as requiring special agents for burning metals such as magnesium
