What is a primary characteristic of Class C fires?

Class C fires are specifically associated with electrical equipment and energized electrical sources. These types of fires can occur when electrical wiring, tools, or devices ignite due to an overload, short circuit, or malfunction. One of the key considerations in fighting Class C fires is the risk of electrocution, which is why it is essential to first ensure that the electrical source has been de-energized before attempting to extinguish the fire.

Using the appropriate extinguishing agent is crucial as well, since water can conduct electricity and pose further hazards. Instead, dry chemical or carbon dioxide extinguishers are often recommended for these fires to mitigate risks while effectively combating the flames.

In contrast, the other classes, such as Class A, B, and D, involve ordinary combustibles, flammable liquids, and combustible metals respectively, which categorize fires based on the materials that are burning rather than the electrical component.
