🔍 Key Concepts

• How fixed CO₂ systems extinguish fires (what they do to the air in the space) • Properties of carbon dioxide gas: visibility, odor, toxicity, and its effect on breathing • Why SCBA (self-contained breathing apparatus) is required for entering enclosed or gas-flooded spaces

💭 Think About

• Think about what happens to the oxygen level in a closed engine room when a large amount of CO₂ is released to fight a fire. • Ask yourself: is CO₂ mainly dangerous because it is directly poisonous, or because it changes the breathing environment in another way? • Consider whether the danger you are protecting against is immediate loss of consciousness/asphyxiation or a more long-term toxic effect.

✅ Before You Answer

• Verify what the primary extinguishing action of CO₂ is in a fixed fire system (cooling vs oxygen displacement). • Check your understanding of whether CO₂ is colorless and odorless and if it is considered toxic or asphyxiating under normal conditions. • Make sure the choice you pick emphasizes the reason SCBA is needed before re-entry: what specific hazard inside the engine room are you guarding against right after discharge?
