A Class C fire extinguisher is designed to extinguish fires involving electrical equipment, such as electrical panels, computers, wiring, and other electrical appliances. These extinguishers use non-conductive extinguishing agents, which means they are safe to use on energized electrical equipment without posing the risk of electrical shock to the person operating the extinguisher.
The typical extinguishing agents used in Class C fire extinguishers include dry chemical powders or clean agents like carbon dioxide (CO2). Dry chemical extinguishers work by interrupting the chemical reaction of the fire, while CO2 displaces oxygen, effectively smothering the fire.
It's important to note that when dealing with a fire involving electrical equipment, it is generally recommended to shut off the power source if it can be done safely. Additionally, after using a Class C fire extinguisher on electrical equipment, it is crucial to have the equipment inspected by a qualified professional before it is put back into service.
