🔍 Key Concepts

• Types of fire extinguishing agents and how they work (water, foam, CO₂, dry chemical) • The primary effect of foam on burning liquids like gasoline or oil • Difference between cooling, smothering, and inerting in fire-fighting

💭 Think About

• Think about what happens physically when a blanket of foam is laid over a burning pool of oil or fuel. What changes for the fuel and the flame? • Ask yourself: does foam mainly lower the temperature, remove oxygen from the whole space, change the chemistry of combustion, or block something from reaching the flames? • Which option best matches what you would see foam doing if you sprayed it over a liquid fuel fire on deck?

✅ Before You Answer

• Verify which extinguishing agents are primarily used for cooling (for example, water) vs. which are used for blocking vapors or oxygen. • Consider that foam forms a blanket over the fuel surface—which of the choices directly relates to that physical action? • Eliminate any option that describes an effect happening in the entire compartment volume rather than right at the fuel surface.
