🔍 Key Concepts
• Fire classification system (A, B, C, D) used in maritime firefighting
• Typical fuels involved in each fire class (ordinary combustibles, flammable liquids, electrical, metals)
• The special behavior of burning metals (e.g., magnesium, sodium) and why they need special agents
💭 Think About
• First, match each answer choice with the type of fuel it normally represents (what burns in class A, B, C, and D?).
• Think about where you would most likely encounter combustible metal fires (for example: in engine rooms, workshops, or cargoes of certain metals).
• Ask yourself: which class is reserved for unusual, high‑temperature metal fires that cannot be put out safely with water or standard foam?
✅ Before You Answer
• Be sure you know that class A involves ordinary combustibles like wood, paper, cloth.
• Confirm that class B is associated with flammable liquids and class C with energized electrical equipment.
• Identify which remaining fire class is specifically designated for combustible metals such as magnesium, titanium, or sodium.
