Class C fires are specifically associated with electrical equipment and are classified in this way because they involve energized electrical sources. When a fire is classified as Class C, it indicates that it is important to use appropriate extinguishing agents that won't conduct electricity or pose a risk of electrocution. For instance, water is not suitable for Class C fires as it can conduct electricity, potentially making the situation more dangerous.

Recognizing a fire's classification helps in selecting the correct fire suppression method. Class C fires require specialized extinguishers, such as those that use carbon dioxide or dry chemical agents, which effectively extinguish the fire without conducting electricity, mitigating the risk to people attempting to put out the fire or to firefighters who may be responding.

In comparison, other classifications focus on different materials or conditions. For example, combustible materials are associated with Class A, flammable liquids are linked to Class B, and ordinary combustibles also refer to Class A fires. Understanding the distinct characteristics of each fire class is crucial for safety and effective fire management.
