Q

Which type of portable fire extinguisher is NOT designed for use on flammable liquid fires?

🔍 Key Concepts

• Fire extinguisher classifications (A, B, C, D, K) and what each is used for • Properties of flammable liquid fires (Class B) • Which agents can spread flammable liquids instead of smothering them

💭 Think About

• First match each extinguisher type with the fire class(es) it is primarily intended to fight • Think about what happens if you spray a strong water stream onto a pool of burning fuel oil or gasoline • Consider which agents work by smothering and interrupting the chemical reaction versus just cooling or pushing the liquid around

✅ Before You Answer

• Verify which extinguisher type is specifically not rated for Class B (flammable liquid) fires • Check which agents are commonly carried on vessels for engine room/galley fuel fires • Confirm which extinguisher type could actually spread a flammable liquid fire rather than put it out
