🔍 Key Concepts

• Class B and Class C fires and how CO₂ extinguishes them • Effect of CO₂ on oxygen and temperature in the fire area • What happens to heat, fuel, and oxygen after CO₂ discharge

💭 Think About

• Think about which part of the fire triangle CO₂ mainly affects and what condition might remain after the gas has dispersed • Consider what could still be present in the compartment even though visible flames are out • Ask yourself which option describes a realistic ongoing hazard that the crew must monitor for after using CO₂

✅ Before You Answer

• Verify which choice deals with leftover conditions at the fire scene rather than damage to equipment • Check which option aligns with standard fire-watch procedures after CO₂ use (what are you watching for?) • Eliminate any choices that describe hazards not normally associated with CO₂ fire extinguishing systems
