🔍 Key Concepts

• Classes of fire extinguishing agents and how they work (cooling, smothering, interrupting chemical chain reaction) • Differences between dry chemical, CO₂, Halon, and water fog in terms of cooling and vapor control • Which agent can create a heat and smoke screen to protect personnel and aid escape

💭 Think About

• For each choice, ask: does this agent mainly cool, mainly smother (displace oxygen), or mainly interrupt the chemical reaction? • Which agent is especially good at absorbing heat and diluting flammable vapors rather than just smothering the fire? • Which agent is commonly used on deck or in machinery spaces to protect personnel by forming a screen between them and the heat/smoke?

✅ Before You Answer

• Verify which agent can both cool the fire area and dilute vapors at the same time • Check which agents (dry chemical, CO₂, Halon) primarily leave little or no residue and act by smothering or chemical inhibition rather than cooling • Identify which choice is specifically associated in training materials with forming a protective heat and smoke screen for firefighting and escape routes
