Which class of fire involves ordinary combustibles?

Class A fires involve ordinary combustibles such as wood, paper, fabric, and certain types of plastics. These materials are common in everyday environments and can ignite easily, producing both visible flames and significant heat. Firefighting strategies for Class A fires typically utilize water as the primary extinguishing agent, which effectively cools the burning material and suppresses the flames.

Understanding the classification of fires is essential for effective fire prevention and response. For instance, while Class B fires pertain to flammable liquids like gasoline and oils, Class C fires involve electrical equipment, and Class D fires concern combustible metals. Each class requires specific materials for suppression due to the unique nature of the burning substances. Therefore, recognizing that Class A specifically addresses ordinary combustibles aids in proper fire safety planning and response efforts.
