In the event of a fire, automatic activation...

🔍 Key Concepts

• Fixed CO₂ fire-extinguishing systems are usually installed to protect enclosed spaces where people do NOT normally stay for long periods • Consider which of the listed spaces are typically treated as special hazards that might have fixed gas systems (rather than just portable extinguishers or sprinklers) • Automatic discharge of CO₂ in an occupied space can be deadly due to oxygen displacement

💭 Think About

• For each choice, ask: Is this space normally manned or unmanned, and how dangerous would automatic gas flooding be to personnel? • Think about which spaces SOLAS and USCG treat as high‑fire‑risk enclosed spaces that often get their own fixed CO₂ systems on ships • Would regulations more likely require manual release with warnings in spaces where crew may be present, or allow fully automatic activation there?

✅ Before You Answer

• Verify in current regulations which spaces are commonly protected by fixed CO₂ systems (e.g., machinery spaces, cargo spaces, paint lockers)** • Check which spaces are typically required to have pre-discharge alarms or manual operation to protect personnel • Before choosing, be sure you are clear on the difference between: space that HAS a fixed CO₂ system vs. space where that system is allowed to be automatic without manual intervention

In the event of a fire, automatic activation of a fixed CO₂ extinguishing system can result in which of the following areas?

Machinery space

Paint locker

Cargo hold

All of the above
