🔍 Key Concepts

• Dry chemical extinguishers work mainly by affecting the combustion process, not just by cooling or displacing oxygen • The fire tetrahedron (heat, fuel, oxygen, chemical chain reaction) and which side dry chemical most directly attacks • Difference between smothering a fire and interrupting the chemical chain reaction

💭 Think About

• Think about what makes dry chemical extinguishers especially effective on flammable liquids and electrical fires compared to water or foam • Ask yourself: does dry chemical mainly cool the fire, block oxygen, block heat, or interfere with the combustion chemistry itself? • Consider how long the extinguishing effect lasts after you stop discharging a dry chemical extinguisher

✅ Before You Answer

• Identify which option refers to the chemical chain reaction part of the fire tetrahedron • Eliminate options that mostly describe cooling or heat shielding, which are not the primary strength of dry chemical agents • Verify which method explains why a relatively small amount of powder can stop a large flame quickly and keep it from immediately re‑igniting
