How does CO2 catch fire

CO2 is a colorless and odorless gas, and it is not flammable under normal conditions. However, when a mixture of CO2 and oxygen reaches a certain level, it can become combustible. To catch fire, a mixture of CO2 and oxygen must be between 15-30% CO2. At this level, it creates an "explosive atmosphere" that can ignite with a spark or flame.
Sources of CO2 and Oxygen
CO2 is abundant in the atmosphere, but it must be mixed with oxygen to become combustible. Oxygen is also found in the atmosphere, but it is generally below the 15-30% range required for CO2 to catch fire.
Combustible Mixtures
When CO2 and oxygen are both present in the air, they can create a combustible mixture. This mixture can be ignited with a spark or flame, and it will burn with a visible flame. If the mixture is too rich in CO2, it will not ignite.
Safety Considerations
When dealing with combustible mixtures of CO2 and oxygen, it is important to take safety precautions. These include using proper ventilation, avoiding sparks and open flames, and wearing protective clothing. It is also important to ensure that the mix of CO2 and oxygen is within the proper range for combustion (15-30% CO2).
