What is one of the classes of fires, and what does it signify?

The class of fires identified as "C" pertains to combustibles, which are solid materials that can ignite and burn. This classification signifies that the fire involves materials such as wood, paper, cloth, plastics, and other solid combustibles. Understanding this categorization is essential for effectively addressing and extinguishing such fires, as different materials require specific methods and types of extinguishing agents. For instance, using water on burning solids is often a suitable method, as it cools the fire and suppresses combustion.

The other options correspond to different classes of fires—electrical fires are classified as class A, whereas flammable liquids fall under class B, and kitchen fires involving oils are classified as class D. Each class has distinct properties and requires specific approaches for safe and effective management, which highlights the importance of correctly identifying fire types.
