🔍 Key Concepts

• CO₂ system characteristics on ships (storage, application, typical spaces protected) • How CO₂ extinguishes fire (oxygen displacement, no residue) • Operational concerns: personnel safety and damage to equipment/cargo

💭 Think About

• Think about what happens inside an enclosed machinery space when CO₂ is released—what effect does it have on equipment and cargo afterward? • Compare CO₂ to water or foam: which agent leaves residue, which can damage machinery, and which does not? • Consider the dangers of CO₂ to people in the space—does that make it more or less ‘safe’ than other agents?

✅ Before You Answer

• Identify which option best matches the well‑known practical benefit of CO₂ in machinery spaces (engine rooms, pump rooms). • Eliminate any option that conflicts with the fact that CO₂ displaces oxygen and is hazardous to personnel in enclosed spaces. • Ask: Among the choices, which one describes something CO₂ is especially known for in shipboard use, compared with water or foam?
