What is the fire extinguisher class for energized electrical equipment?

The fire extinguisher class for energized electrical equipment is Class C. Fire extinguishers are categorized based on the type of fire they are designed to combat, and Class C specifically addresses fires that involve electrical equipment, such as wiring, outlets, or any devices that are energized.

Using the correct type of extinguisher is crucial for safety, as using an unsuitable extinguisher on an electrical fire could result in electrical shock or the fire spreading. Class C extinguishers typically use non-conductive agents, which helps to extinguish the fire without conducting electricity back to the user.

In contrast, Class A extinguishers are designed for ordinary combustible materials like wood and paper, Class B extinguishers are meant for flammable liquids, and Class D extinguishers are suitable for combustible metals, ensuring proper fire suppression tailored to specific hazards. Understanding these classifications helps ensure the right response in case of a fire involving electrical equipment.
