What is the expansion ratio of carbon dioxide when discharged?

• A. 450 to 1
• B. 400 to 1
• C. 300 to 1
• D. 500 to 1

Answer: (A)

The correct answer reflects that the expansion ratio of carbon dioxide (CO2) when discharged is indeed 450 to 1. This means that for every 1 unit of liquid carbon dioxide released, it converts into 450 units of gas at atmospheric pressure and temperature. This significant expansion makes CO2 an effective agent for fire suppression, as it can rapidly fill a space with gas to displace oxygen and help extinguish flames. Understanding the expansion ratio is crucial for handling and deploying fire suppression systems effectively, particularly in aviation environments where rapid response is essential. Each value reflects different gas behaviors; however, the specific characteristics of CO2, including its ability to displace oxygen effectively to enhance fire suppression, are best represented by the 450 to 1 expansion ratio.
