When carbon dioxide can't be used to put out fire?

Answer 1

The weakness of carbon dioxide as a fire fighting agent is that it blows away very easily, so in an environment in which there is any wind, you are not going to get a good result. Most fire extinguishers are designed to use a powdered fire suppressant rather than a gas.

Answer 2

Carbon dioxide is typically effective at extinguishing fires because it displaces oxygen, which starves the fire of this essential element. However, if the fire is fueled by chemicals or metals that do not require oxygen to burn, carbon dioxide may not be effective in suppressing the fire. In such cases, other fire suppression methods that target the specific fuel source are necessary.
