Which type of fire is associated with ordinary combustibles?

Class A fires are specifically associated with ordinary combustibles, which include materials such as wood, paper, cloth, rubber, and many plastics. These types of fires typically require water or other agents that can effectively cool and extinguish the burning material.

Understanding the classification is vital for firefighters as it helps determine the most appropriate firefighting techniques and extinguishing agents. For instance, using water on a Class A fire helps to absorb the heat and prevent re-ignition of the combustibles. Choosing the correct class of fire is essential for safety and effectiveness when addressing various fire scenarios, as different classes have different properties and behaviors.
