What type of fire extinguisher is designed for fires involving wood and paper?

The correct answer is based on the classification of fire extinguishers, which are designated by letters that indicate the types of materials they are effective against. A fire extinguisher labeled as Type A is specifically designed for fires involving ordinary combustible materials, such as wood and paper. This type of extinguisher uses water or special agents to cool the burning materials and extinguish the fire.

In contrast, Type B extinguishers are intended for fires involving flammable liquids such as oil and gasoline. Type C extinguishers are suitable for electrical fires, as they use non-conductive agents to prevent the risk of electrical shock. Type D extinguishers are designed for fires involving combustible metals, such as magnesium and titanium. Therefore, for fires that include wood and paper, Type A is undeniably the appropriate choice.
