🔍 Key Concepts

• Fixed CO₂ fire-extinguishing systems in machinery spaces • Dangers of entering a space that is about to be or has been flooded with CO₂ • Purpose of remote emergency shutdowns for fuel and ventilation

💭 Think About

• If the automatic shutoffs for fuel and ventilation do NOT work, what is the safest way to achieve the same result without exposing anyone to CO₂? • Which options would increase the effectiveness of the CO₂ system, and which could actually make the situation more dangerous for personnel? • Think about the sequence: first, make the space safe and sealed; then, allow the extinguishing agent to work. Which action best supports that sequence?

✅ Before You Answer

• Eliminate any option that requires sending a person into a space that is, or soon will be, filled with CO₂. • Eliminate any option that would change the designed quantity of CO₂ without engineering justification. • Focus on the option that uses remote controls to stop fuel and ventilation while keeping all personnel out of the engine room.
