Which type of fire extinguisher is best suited for Type C fires?

The best choice for Type C fires, which involve energized electrical equipment, is a carbon dioxide fire extinguisher. Carbon dioxide extinguishers work by displacing oxygen, which is essential for combustion, while not causing any electrical conductive damage or residue that can affect sensitive equipment. This makes them particularly effective and safe for use on electrical fires, as they can effectively suffocate the flames without introducing water or other materials that could lead to further electrical hazards.

Using a carbon dioxide extinguisher also provides the advantage of being non-conductive, ensuring that the risk of electric shock is minimized while combating the fire. In environments like server rooms, laboratories, or any areas with significant electrical equipment, carbon dioxide extinguishers are preferable for these very reasons.

Other types of extinguishers, while they may handle various classes of fires effectively, could comprise water mist, which may not be adequate for electrical fires, and even dry chemical or halogenated agents, which might leave residues that can damage sensitive electrical components. Thus, carbon dioxide remains the optimal choice for addressing Type C fires safely.
