Class C fires specifically involve fires that are fueled by electrical energy. These fires can occur in situations where electrical equipment, wiring, or appliances are improperly used, faulty, or malfunctioning, leading to overheating and combustion.

It is crucial to identify Class C fires correctly because using the wrong type of extinguishing agent can create additional hazards. For instance, using water on an electrical fire can lead to electrocution or spread the fire further. Instead, Class C fires should be extinguished using agents designed for electrical fires, such as dry chemical or carbon dioxide extinguishers, which do not conduct electricity.

Understanding the nature of Class C fires is foundational for fire safety and response, particularly in residential, commercial, and industrial settings where electrical equipment is prevalent.
