What is one of the main advantages of using carbon dioxide as a fire extinguisher?

Using carbon dioxide as a fire extinguisher offers the significant advantage of not leaving any residue after use. This characteristic makes it ideal for situations where cleanliness is a priority, such as in electronic equipment rooms or areas containing sensitive materials, where any leftover substance could cause damage or require extensive cleanup. The gas works by displacing oxygen, which suffocates the fire without introducing additional residue that could complicate post-fire recovery efforts.

Carbon dioxide is particularly useful in extinguishing fires that involve flammable liquids or energized electrical equipment, provided the environment is appropriate, as it does not conduct electricity and will not leave behind any contaminants. Thus, the absence of residue is a critical advantage for maintaining the integrity of the surrounding area and equipment after an incident.
