🔍 Key Concepts
• Fire classification system (A, B, C, D, K) and what each one is based on (fuel type)
• Difference between solid combustibles, flammable liquids, electrical, and metal fires
• Typical shipboard examples of each fire class (wood, oil, wiring, magnesium)
💭 Think About
• Think about what type of fuel "oil" is on a vessel: is it a solid material, a liquid, an electrical source, or a metal?
• Ask yourself which fire class includes flammable liquids like fuel, paint thinner, or solvents.
• Consider which class you would use a foam or dry chemical extinguisher on when dealing with a fuel spill fire.
✅ Before You Answer
• Match oil to the correct fuel category (solid, liquid, gas, metal, or electrical equipment).
• Recall which class is specifically defined as flammable liquid and gas fires in marine firefighting training.
• Eliminate any classes that clearly apply to ordinary combustibles, energized electrical equipment, or combustible metals rather than liquids.
