What type of extinguisher is suitable for a type C fire?

A type C fire involves live electrical equipment, making its management unique compared to other classes of fires. The most suitable extinguishing agents for a type C fire are non-conductive, specifically designed to eliminate the risk of electrical shock.

Dry chemical extinguishers are particularly effective for type C fires because they work by interrupting the chemical reaction of the fire, and they are non-conductive, ensuring they can be safely used around energized electrical components. Common dry chemical agents include monoammonium phosphate, which can effectively suppress flames without creating a safety hazard regarding electrical conductivity.

While carbon dioxide extinguishers are also appropriate for class C fires due to their non-conductive nature and ability to displace oxygen, dry chemical extinguishers generally offer a more versatile approach as they are effective on multiple fire classes, including classes A and B.

In contrast, water-based and foam extinguishers are ineffective and hazardous on type C fires, as they can conduct electricity and pose a risk to the operator. Thus, the choice of a dry chemical extinguisher is optimal for effectively handling type C fire scenarios.
