🔍 Key Concepts

• Fire classification system used on ships and in maritime regulations • Difference between fires involving ordinary combustibles, flammable liquids, electrical equipment, and combustible metals • Which class of fire requires special dry powders and must NOT be fought with water or foam

💭 Think About

• First match each answer choice (A–D) with the type of material that normally defines that fire class. • Think about which type of fire would involve things like wood, paper, cloth, which one involves fuels and oils, which one involves energized electrical equipment, and which one involves reactive metals like sodium or magnesium. • Consider which fire class is known for needing special agents and being dangerous to fight with water because of possible violent reactions.

✅ Before You Answer

• Before choosing, be sure you can state in your own words what each fire class (A, B, C, D) usually covers. • Double-check which class is specifically associated with combustible metals rather than just "metal objects" or electrical circuits. • Confirm in your mind which fire class is often illustrated in training materials with pictures of magnesium, sodium, or other metal shavings.
