🔍 Key Concepts

• Fixed CO₂ systems displace oxygen and can be deadly to people in the space • CO₂ flooding procedures require certain safety steps before discharge • Engine room manning and evacuation requirements during gas flooding

💭 Think About

• Ask yourself: which action is absolutely necessary so that the CO₂ system does not endanger human life? • Which of these steps, if NOT done, could make the use of CO₂ a violation of basic safety procedures? • Think about the sequence: what must be confirmed or completed FIRST, before any other fire‑fighting or machinery actions matter?

✅ Before You Answer

• Verify which step directly ensures no personnel are left in the protected space • Consider the primary hazard of CO₂: asphyxiation, not equipment shutdown • Check typical fixed gas system operating instructions: what must be done and confirmed before pulling the release?
