🔍 Key Concepts

• Fire tetrahedron (heat, fuel, oxygen, and chemical chain reaction) • How halogenated agents (Halon) interact with a flame at the molecular level • Difference between smothering, cooling, and interrupting combustion

💭 Think About

• Think about whether Halon mainly removes heat, removes oxygen, or interferes with the combustion chemistry itself. • Compare what foam extinguishers do versus what gas-type clean agents (like CO₂ and Halon) do. • Consider why Halon systems are effective in spaces with delicate electronics, where residue or large temperature changes are undesirable.

✅ Before You Answer

• Verify which fire extinguishing mechanism is associated with chemical chain reaction rather than just heat or oxygen removal. • Check what foam specifically does (how it forms a blanket over the fuel) and whether Halon behaves that way. • Confirm whether Halon 1301 significantly cools the fire area or instead works in another primary way.
