Class C is the correct answer.
Class C fire extinguishers are specifically designed for fires involving electrical equipment or energized electrical systems. Here’s why you should use a Class C fire extinguisher on an electrical fire:
- Non-Conductive Agent: Class C fire extinguishers contain non-conductive extinguishing agents, such as dry chemical powders or clean agents like carbon dioxide (CO2). These agents are non-conductive, which means they do not conduct electricity. When used on electrical fires, they won’t create a path for electrical current to flow through, reducing the risk of electrical shock to the person operating the extinguisher.
- Effective on Electrical Fires: Class C extinguishing agents are effective at extinguishing fires involving electrical equipment because they smother the fire by removing the heat and interrupting the chemical reaction of combustion. Dry chemical powders, for example, work by creating a barrier between the fuel and oxygen, effectively cutting off the fire’s fuel source.
- Versatility: Class C fire extinguishers are versatile and can also be used on Class A (ordinary combustibles) and Class B (flammable liquid) fires. This versatility can be helpful in situations where multiple types of fire hazards are present.
