🔍 Key Concepts

• CO2 fire extinguishing systems work by displacing oxygen and smothering the fire • The importance of ventilation control during an engine-room fire • What happens if you add more air to a combustion process

💭 Think About

• Ask yourself: For CO2 to stay effective inside an enclosed space, what must happen to the openings to that space? • What effect would running blowers or leaving doors/vents open have on CO2 concentration and the fire? • Which option best supports the idea of smothering the fire rather than feeding it?

✅ Before You Answer

• Verify which choices increase air flow to the fire and which reduce or stop it • Identify the option that helps contain CO2 inside the engine compartment • Eliminate any choice that would allow fresh air to enter and support combustion
