Is carbon dioxide flammable?

Carbon dioxide is classified as a non-flammable gas. This means that it does not support combustion and will not ignite regardless of the concentration or the presence of other substances, including oxygen. Its primary role in firefighting is as a means to displace oxygen, which is necessary for fire to sustain itself. Therefore, carbon dioxide is effective in extinguishing flames, making it an important gas in fire suppression systems and equipment.

In summary, the assertion that carbon dioxide is non-flammable is correct, reinforcing its use as a safety measure rather than as a fuel source. Understanding these properties is crucial in medical and industrial settings where gas administration occurs.
