Which class of fire does a Class A extinguisher combat?

A Class A extinguisher is specifically designed to combat ordinary combustibles, which include materials like wood, paper, and cloth. These substances are characterized by their ability to ignite easily and produce significant flames during combustion. The extinguishing agents in Class A extinguishers, such as water or foam, work by cooling the burning material and reducing the oxygen supply necessary for the fire to continue burning. It is important to use the appropriate type of extinguisher for the specific class of fire to ensure safety and effectiveness; using the wrong extinguisher can sometimes exacerbate the situation instead of controlling it. Therefore, understanding that Class A is geared towards ordinary combustibles is essential for proper fire safety practices.
