Q

Which statement describes the primary process by which fires are extinguished by dry chemical?

🔍 Key Concepts

• Fire tetrahedron (heat, fuel, oxygen, chemical chain reaction) • How dry chemical extinguishers work compared to water or foam • Difference between smothering, cooling, and interrupting the chemical reaction

💭 Think About

• Ask yourself: Does dry chemical mostly cool the fire, block the air, or interfere with the flame’s chemistry? • Think about why dry chemical is effective on both flammable liquids and electrical fires—what does that suggest about its main action? • Which choice best matches the idea of stopping the flame from sustaining itself, beyond just covering or cooling it?

✅ Before You Answer

• Verify which part of the fire tetrahedron dry chemical mainly targets. • Check whether the option talks about temperature reduction, oxygen exclusion, or chain reaction interruption. • Confirm that the description matches how common ABC dry chemical extinguishers are taught to work in maritime fire training.
