Answer :
Final answer:
For fires fueled by wood, paper, and trash, which are classified as ordinary combustibles, a Class A fire extinguisher should be used. This type of extinguisher can use water, foam, or dry chemical to extinguish the fire. Dry-cleaning solvents were once used in fire extinguishers but are no longer recommended.
Explanation:
The class of fire extinguisher that should be selected for fires fueled by wood, paper, and trash is a Class A extinguisher. This type specifically targets ordinary combustibles such as paper, cloth, wood, and most plastics. It is important to note for safety reasons, that these extinguishers use pressurized water, foam, or a dry chemical that can douse this type of fire effectively.
In contrast, fire extinguisher systems that might feature foaming agents are designed for different types of fires. This foam is typically used for fires involving flammable and combustible liquids, which would be a Class B fire, not for ordinary combustibles. Additionally, certain foams are effective for firefighting on a larger scale such as in situations with burning organic liquids.
Historically, some fire extinguishers included dry-cleaning solvents, although these are no longer recommended for use. With the evolution of extinguishing agents over time, modern systems are designed to be more effective and environmentally friendly for a variety of fire scenarios including those in residential settings where wood burning might occur.
