What type of fire does Class "A" refer to?

Class "A" fires are classified as fires that involve ordinary combustible materials. This includes common substances such as wood, coal, paper, fabric, and some plastics. The reason wood or coal is designated as a Class "A" fire is due to their ability to ignite, burn, and create embers that can lead to further combustion when they come into contact with additional combustible materials.

Extinguishing Class "A" fires typically involves methods that cool the burning material or eliminate oxygen from the fire, often through the use of water or other agents designed for combustion suppression. Understanding this classification is crucial for safety and fire prevention measures, as using the wrong type of extinguisher on different classes of fire can be ineffective or even dangerous.
