What is the expansion ratio of CO2?

• A. 300 to 1
• B. 450 to 1
• C. 600 to 1
• D. 750 to 1

Answer: (B)

The expansion ratio of carbon dioxide (CO2) is critical in various applications, particularly in fire suppression systems where CO2 is used as an extinguishing agent. The correct expansion ratio of CO2 is 450 to 1, meaning that when CO2 is released from its liquid form, it expands to 450 times its original volume in gas form. This significant increase in volume allows a relatively small amount of liquid CO2 to produce a large volume of gas, which can effectively displace oxygen and extinguish fires. This property is beneficial because it allows for efficient storage and utilization in firefighting equipment. The high expansion ratio ensures that a small tank of liquid CO2 can produce enough gas to stifle flames without using excessive amounts of space or weight in the firefighting apparatus. Understanding the expansion ratio is crucial for safely and effectively managing CO2 fire suppression systems.
