Which type of fire extinguisher is classified as "A"?

The classification of fire extinguishers is based on the types of fires they are designed to combat. A fire extinguisher classified as "A" is specifically meant for fires that involve ordinary combustible materials, such as wood, paper, and trash. This type of extinguisher typically contains water or water-based solutions, which are effective in extinguishing fires fueled by these common materials.

The ability to effectively deal with these types of fires is critical since they are often found in residential and commercial environments, making the "A" classification an essential part of fire safety protocols. Understanding this classification helps in selecting the right extinguisher for specific fire scenarios, ensuring effective responses to emergencies.
