🔍 Key Concepts

• Types of fire agents and what each is best used for (liquid fuel, electrical, ordinary combustibles) • Characteristics of an aviation fuel spill or crash fire (spreading, re-ignition, surface burning) • Why some agents can actually spread burning fuel instead of controlling it

💭 Think About

• Think about what is actually burning in a helicopter crash and how that fuel behaves on the surface. • Ask yourself which agent can form a blanket over liquid fuel to prevent oxygen from reaching it and to stop re-ignition. • Consider which agents are better suited only for enclosed spaces or electrical components, not large open-air fuel spills.

✅ Before You Answer

• Identify which choice is specifically designed for flammable liquid (Class B) fires, especially fuel spills. • Eliminate any agents that mainly work by displacing oxygen in a confined space rather than blanketing a surface. • Make sure your choice would control spread of burning fuel on the deck/ground, not push or splash it further.
