According to Creative Safety Supply, Class C fire extinguishers typically use carbon dioxide (CO2) and dry chemical agents that can safely smother an electrical fire.

It’s important to note that while all Class C extinguishers are suitable for electrical fires, they may also be rated for Class A and B fires, which involve common combustibles and flammable liquids, respectively. This multi-class rating can be advantageous for homeowners as it provides versatility in tackling various types of domestic fires.

Below is a table that outlines the types of agents found in Class C fire extinguishers:

Extinguishing Agent Description
Carbon Dioxide (CO2) Quickly removes heat and displaces oxygen.
Dry Chemical Interrupts the chemical reaction of the fire triangle (oxygen, heat, fuel).

Suitable Extinguishing Agents

When choosing the best extinguishers for electrical fires, it’s essential to consider the type of extinguishing agent. The following agents are recognized for their effectiveness in combating Class C fires:

  • Carbon Dioxide (CO2): This agent is non-flammable and does not leave any residue, making it a clean option for electrical fires. It works by displacing the oxygen that the fire needs to continue burning.
  • Dry Chemical: Agents such as monoammonium phosphate, potassium bicarbonate, and potassium chloride are common in dry chemical extinguishers. They create a barrier between the fuel and the oxygen, effectively smothering the fire.

For more detailed information on the types of fire extinguishers and their uses, refer to the guide on types of fire extinguishers for electrical fires.

Homeowners should be aware that using water or water-based extinguishing agents on a Class C fire is hazardous. Water conducts electricity and can exacerbate the fire or cause electric shock. Therefore, it’s vital to have a Class C rated extinguisher readily available in areas where electrical fires are a risk, such as kitchens, laundry rooms, or near electrical panels.
