What type of fire class is characterized by common combustibles?

Class A fires are characterized by common combustibles, which typically include materials such as wood, paper, cloth, rubber, and certain plastics. These types of fires are the most common and involve ordinary combustibles that you might find in typical buildings or homes. The extinguishing agents for Class A fires are usually water and foam, which cool the burning material and remove heat from the reaction.

In the context of fire safety, the classification system helps first responders, fire safety directors, and individuals understand the nature of the fire they might encounter and the appropriate methods to extinguish those fires safely and effectively. Recognizing that Class A fires involve ordinary materials is crucial for effective fire prevention and response strategies.
