For fires involving wood, paper, and fabric, which are classified as Class A fires, the appropriate types of fire extinguishers to use are:
- Water fire extinguishers: They work by cooling the burning material and are commonly used for organic materials like wood, paper, and fabrics. They should not be used on electrical fires or flammable liquid fires.
- Foam fire extinguishers: These can also be used on Class A fires. They work by cooling and creating a barrier between the fuel and flame.
- Dry powder extinguishers: Safe for use on wood, paper, and fabric fires as well as flammable liquid and electrical fires.
- Wet chemical extinguishers: Suitable for wood, paper, and fabric fires and also for kitchen fires, but not for flammable liquids or electrical fires.
The most common and recommended type for ordinary combustibles like wood, paper, and fabric is a Class A fire extinguisher, which can be water-based, foam, dry powder, or wet chemical depending on the specific environment and risk factors.
