🔍 Key Concepts

• Class B fires involving flammable liquids like fuel • The importance of removing the source of fuel in the fire triangle (fuel, heat, oxygen) • Sequence of actions in an engine-room fuel leak fire

💭 Think About

• Which action will immediately stop more fuel from feeding and spreading the fire? • Among the options, which step is usually done BEFORE choosing a specific type of extinguisher? • Is it safer to attack the flames directly, or to first control the source of the burning material?

✅ Before You Answer

• Identify which option deals directly with stopping the fuel flow rather than treating just the visible flames • Consider standard engine-room emergency procedures for a ruptured fuel line • Eliminate options that mainly focus on extinguisher type or improvised smothering instead of controlling the fuel source
