In this case, a carbon dioxide extinguisher can be used to eliminate the fire by displacing the oxygen that the fire relies upon for fuel.īecause carbon dioxide is a non-conductive material, CO 2 extinguishers are also useful for extinguishing electrical (Class C) fires and were originally developed for this purpose. The reaction may inadvertently cause the flaming liquid to displace or splash, and water may not be able to reduce the heat from the fire to a low-enough temperature to terminate the combustion reaction that keeps the fire burning.
When you gaze at the leaping flames of a campfire, you’re observing not an object, but a process.
In the mythology of virtually every culture, fire is a sacred substance that gives life or power.

The ancient Greeks believed that fire was one the four basic elements that composed all things in the universe. Safeopedia Explains Carbon Dioxide Fire Extinguisher
