Which type of fire extinguisher is suitable for use on a paper or wood fire?

1. Type A

2. Type B

3. Type C

4. Type D

The correct answer is: Type A

A Type A fire extinguisher is designed specifically for fires involving ordinary combustibles such as paper, wood, and some plastics. These materials typically burn in a manner that allows for water or water-based extinguishing agents to effectively smother the flames. This type of extinguisher often contains water or a foam that can absorb heat and cool down the burning material, thereby extinguishing the fire. Other types of extinguishers are designated for different classes of fires. Type B extinguishers are suitable for flammable liquids like gasoline and oils; Type C extinguishers are used for electrical fires; and Type D extinguishers are designed for combustible metals. Thus, while each type has a specific application, the Type A extinguisher is uniquely suited for tackling fires involving paper and wood.
