Which type of fires are primarily caused by electrical equipment?

Class C fires are specifically associated with electrical equipment and are defined as fires that involve energized electrical circuits or appliances. This classification is crucial because the handling and extinguishing of Class C fires require a different approach and set of precautions when compared to other classes of fires. For example, using water to extinguish a Class C fire can be extremely dangerous, as water is a conductor of electricity and could lead to electrocution. Instead, special fire extinguishers rated for Class C fires, which contain non-conductive agents, should be used.

In contrast, Class A fires involve ordinary combustible materials such as wood, paper, or cloth, while Class B fires are fueled by flammable liquids or gases. Class D fires involve combustible metals, which require specific types of extinguishing agents that are not suitable for electrical fires. Understanding these classifications helps ensure not only effective firefighting strategies but also the safety of individuals dealing with fire emergencies.
