🔍 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.
