What is the best fire extinguisher for a Class C fire?

Energized Electrical fires are categorized as Class C fires. This means that the fire is fueled by electricity. Once the Electricity is removed or shut off, the fire is no longer classified as a Class C fire.

What is the best fire extinguisher for a Class C fire? For fires that involve sensitive equipment such as computers, servers, data centers, or other electrical equipment, Carbon Dioxide and Halotron Fire extinguishers are the best options to extinguish the fire without damaging the sensitive equipment. If the electrical fire doesn’t involve sensitive equipment, then an ABC or Standard BC fire extinguisher will extinguish Class C fire.

Each type of fire extinguisher on the market today use a different agent to effectively extinguish the fire. Review the chart below to see the different fire extinguishers and the agent used in them.

Extinguisher Type Agent Used Agent Type
ABC Class Fire Extinguishers Dry Chemical Monoammonium Phosphate Dry Chemical
Standard BC Fire Extinguishers sodium bicarbonate-based agent Dry Chemical
Halotron Fire Extinguishers Halotron I Clean Agent
Carbon Dioxide Fire Extinguishers Carbon Dioxide (Pressured Gas) Clean Agent

As mentioned above, not all Class C fires are the same. Fires that involve sensitive electrical equipment need to be extinguished by a clean agent fire extinguisher otherwise the Dry Chemical, Monoammonium Phosphate or sodium bicarbonate may damage the electrical equipment due to its corrosive and damaging properties on electrical equipment.

Dry Chemical vs Clean Agent

Dry Chemical: Fire extinguishers such as the ABC Class fire extinguisher or the Standard BC Class fire extinguishers use a light, fine solid powder that extinguishes the fire. While the ABC Class fire extinguisher is effective in fighting Class A, Class B, and Class C fires, the dry chemical powder needs to be cleaned up after it has been discharged.

Clean Agent: The Halotron I and the Carbon Dioxide fire extinguishers are known as “clean agent” fire extinguishers. Agents used in these fire extinguishers are residue-free and easy to clean up after it has been discharged.  The Halotron fire extinguishers are designed to extinguish Class A, Class B, and Class C fires while the Carbon Dioxide Fire extinguishers are only designed to extinguish Class B and Class C fires.

Portable vs Wheeled Class C Fire Extinguishers

Portable fire extinguishers are found in both public and private settings such as offices, homes, stores, and malls.

Potable fire extinguishers are available in the following design types: ABC Class, BC Class, Carbon Dioxide and Halotron I.

Wheeled Fire Extinguishers: Wheeled fire extinguishers are much larger, typically between 50 pounds to 350 pounds which allow them to extinguish larger fires. Due to its larger design and extinguishing capabilities, wheeled fire extinguishers are typically found in the following places: cruise liners, warehouses, data centers, boat docks, oil rigs, and airports.

Wheeled fire extinguishers are available in the following design types: ABC Class, BC Class, Carbon Dioxide and Halotron I.

Related Questions:

For sensitive equipment, is the Halotron I or Carbon Dioxide fire extinguisher better?
It’s difficult to say which of the two fire extinguishers is better without knowing the environment in which it will be used.

However, it is important to note that the halotron fire extinguishers are capable of extinguishing Class A, Class B, and Class C fires. Whereas the Carbon Dioxide fire extinguisher is only capable of extinguishing Class B and Class C fires.

If there is a chance that a Class A fire may occur in the office or building where the fire extinguisher will be used, it is better to get the Halotron fire extinguisher.
