What type of fire extinguisher is suitable for electrical fires?

A Class C fire extinguisher is specifically designed for use on electrical fires. These extinguishers contain non-conductive agents such as carbon dioxide (CO2) or dry chemical compounds that effectively suppress fires without posing a risk of electric shock. Since electrical fires involve energized electrical equipment, using a water-based extinguisher, such as those found in Class A, would be dangerous as water conducts electricity and could lead to further hazards.

Class B extinguishers are intended for flammable liquids and gases, while Class D extinguishers are used for combustible metals. Each type of extinguisher is tailored for specific fire classes, ensuring safety and effectiveness based on the materials burning. Therefore, for fires involving electrical equipment, the safest and most appropriate choice is a Class C extinguisher.
