Which type of fire extinguisher can be used on wood, paper, and cloth fires?

The correct choice focuses on the properties of Class A fire extinguishers, which are specifically designed to combat fires involving ordinary combustible materials such as wood, paper, and cloth. These materials are prevalent in many environments, including homes and schools, making Class A extinguishers essential for general fire safety.

When using a Class A extinguisher, the agent it employs is effective in penetrating and cooling the burning material, helping to extinguish fires before they can spread. This ability to extinguish fires that arise from these common combustibles is crucial in a fire safety protocol, as it addresses the majority of fire risks encountered.

Class C extinguishers are intended for electrical fires, Class B are used for flammable liquids and gases, and Class D is specifically designed for combustible metals. Each of these extinguishers has its designated purpose and should not be used for other types of fires. Understanding the appropriate use of each fire extinguisher type is vital for effective fire safety measures.
