🔍 Key Concepts

• Fire classes and typical fuels (e.g., ordinary combustibles, flammable liquids, electrical fires, combustible metals) • How flammable liquids are categorized in marine firefighting • Difference between fuel type and source of ignition when classifying fires

💭 Think About

• Ask yourself: Is diesel oil a solid, liquid, or metal fuel, and does that matter for the fire class? • Consider which fire class is associated with flammable or combustible liquids like oil, gasoline, and solvent. • Think about whether the presence of electrical equipment changes the fire class, or if the class is based mainly on what is burning.

✅ Before You Answer

• Match each class (A, B, C, D) to its correct fuel type before choosing. • Verify which class specifically names flammable or combustible liquids in your study materials. • Make sure you are classifying the burning diesel oil itself, not the equipment or wiring that might have started the fire.
