What type of extinguishing agent is recommended for Class C fires?

Class C fires involve energized electrical equipment, and the use of certain extinguishing agents is crucial for safety and effectiveness. Dry chemical agents are specifically designed to interrupt the chemical reaction of the fire and create a barrier between the fuel and the oxygen, which helps to extinguish the flames without conducting electricity.

Using water on Class C fires is dangerous because water is a conductor of electricity and can create the risk of electrocution for the firefighter or anyone nearby. Foam is typically used for Class B fires, which involve flammable liquids, and while it can smother flames, it is not ideal for electrical fires since it may not effectively disrupt the chemical reaction caused by the electrical components. Dirt is impractical for extinguishing electrical fires and doesn’t provide the rapid reaction needed to safely and effectively put out such fires. Therefore, dry chemical agents are the most suitable and recommended choice for safely managing Class C fires.
