Which of the following is a characteristic of Class A fires?

Class A fires are characterized by the presence of ordinary combustibles, which include materials such as wood, paper, cloth, rubber, and many plastics. These are the most common types of fires that firefighters encounter. The materials involved in Class A fires ignite easily and burn with a steady flame, making them a key focus for fire strategy and suppression techniques.

Understanding this classification helps firefighters to select the appropriate extinguishing agent, such as water or foam, which can effectively cool and extinguish such fires. Recognizing the nature of Class A fires is crucial for both prevention and firefighting efforts, allowing for better preparation and response to incidents involving these ordinary combustibles.
