Fixed CO2 systems would not be used on...

🔍 Key Concepts

• Fixed CO₂ fire‑extinguishing systems – how they work and why they’re dangerous to people • Where CO₂ systems are normally installed on ships (e.g., machinery spaces, cargo spaces, some lockers) • Regulatory rule of thumb: CO₂ is used in enclosed, normally unoccupied fire‑risk spaces, not where people live or gather

💭 Think About

• Ask yourself: In which space would releasing CO₂ be especially unsafe because people are normally present and need breathable air? • Which spaces on the list are enclosed fire hazards where it is acceptable for everyone to evacuate before flooding with CO₂? • Which option describes an area that, by definition, cannot really be "flooded" with CO₂ because the gas would quickly disperse?

✅ Before You Answer

• Identify which choices are normally occupied living spaces versus unoccupied hazard spaces. • For each option, check whether it is enclosed enough to hold a CO₂ concentration that can smother a fire. • Eliminate any option that is a standard application for fixed CO₂ systems on ships (think machinery spaces, certain cargo spaces, and high‑hazard lockers).
