🔍 Key Concepts

• Fire classes (A, B, C) and which agents are suitable for each • How ABC dry chemical extinguishers work versus CO₂ extinguishers • The difference between smothering, cooling, and burn-back protection

💭 Think About

• Think about which fire classes carbon dioxide is normally rated for, and which fire classes an ABC extinguisher is rated for. • Ask yourself: which of the listed advantages is something CO₂ already does well, and which one is unique to ABC dry chemical? • Consider how each agent actually puts out the fire: does it mainly remove oxygen, cool the fuel, or coat the surface to prevent re‑ignition?

✅ Before You Answer

• Verify which classes of fire CO₂ is commonly approved for and compare that to ABC dry chemical. • Check whether toxicity is really a distinguishing advantage between these two agents in normal use. • Confirm which agent, if any, is known for burn-back protection (preventing re‑ignition after the flame is out).
