Question 1 of 27070

On cargo vessels, the discharge of the required quantity of carbon dioxide into any "tight" space shall be completed within what time period?

🔍 Key Concepts

• Fixed CO₂ fire-extinguishing systems on cargo vessels • Regulatory requirement for CO₂ discharge time into an enclosed or tight space • How quickly a CO₂ system must reach its designed concentration to be effective in smothering a fire

💭 Think About

• Think about why CO₂ needs to reach its full concentration quickly in a closed space. What happens if it takes too long? • Consider whether regulations for fixed CO₂ systems aim for very rapid knockdown or a slower, prolonged release. • Ask yourself: is the required time period closer to an immediate emergency response, or more like a gradual control measure?

✅ Before You Answer

• Check the specific CFR 46 section that covers fixed gas fire-extinguishing systems on cargo vessels. • Verify the definition of a "tight" space as used in fire protection regulations (enclosed space with little leakage). • Confirm the maximum allowable time (not minimum) for completing the discharge of the required CO₂ quantity in such a space.
