One of the disadvantages of using carbon dioxide to extinguish a fire in an enclosed space is __________.

🔍 Key Concepts

• CO2 fire suppression systems behavior in enclosed spaces • Health effects of high CO2 concentrations on humans • Physical properties of carbon dioxide gas compared to air (heavier or lighter?)

💭 Think About

• Think about what happens to people who remain inside a space that has been flooded with CO2 to put out a fire. • Consider whether CO2 itself is toxic, or whether the danger comes from something else it does to the air you breathe. • Review whether CO2 lingers or dissipates quickly in an enclosed compartment, and how its weight relative to air affects where it collects.

✅ Before You Answer

• Verify whether CO2 is heavier or lighter than air and where it settles in a compartment. • Check if CO2 "snow" is considered toxic or mainly a temperature/visibility issue. • Confirm what primary hazard to personnel is always emphasized in training for fixed CO2 systems in machinery spaces and other enclosed areas.

Question 1 of 27070

One of the disadvantages of using carbon dioxide to extinguish a fire in an enclosed space is __________.

prolonged exposure to high concentrations of CO2 gas causes suffocation

the "snow" which is sometimes discharged along with the gas is toxic

rapid dissipation of the CO2 vapor

the CO2 gas is lighter than air and a large amount is required to extinguish a fire near the deck
