There are two disadvantages to CO2 as a firefighting agent. One of these is the limited quantity available, which is the other?

🔍 Key Concepts

• Properties of CO2 as a smothering agent (how it actually puts out fire) • Difference between smothering and cooling in firefighting • Behavior of CO2 in high heat and its use with/without ship’s power

💭 Think About

• Think about how CO2 stops a fire: does it mainly remove oxygen, cool the fuel, or both? Which of the options best matches that characteristic? • Consider what happens to hot metal, bulkheads, or cargo right after a CO2 discharge. Would any of these choices explain why a fire might re‑ignite? • Look at each option and ask: is this a widely known, general limitation of CO2 systems on ships, or something that sounds unlikely or too specific?

✅ Before You Answer

• Verify which option correctly describes CO2’s primary firefighting action (smothering vs cooling). • Check which statement reflects a real, commonly taught limitation of CO2 systems in marine firefighting manuals. • Eliminate any option that conflicts with basic fire science: how CO2 behaves under heat and whether it needs electrical power to be released from fixed systems.

Question 1 of 27070

There are two disadvantages to CO2 as a firefighting agent. One of these is the limited quantity available, which is the other?

There is no effect on a class A fire even in an enclosed space

The lack of cooling effect on heated materials

That it breaks down under extreme heat to form poisonous gases

That it cannot be used in a dead ship situation with no electrical power to the CO2 pump
