Which class of fire extinguishers is designated for use on wood, paper, and plastic fires?

• A. A
• B. B
• C. C
• D. D

Answer: (A)

The class of fire extinguishers designated for use on wood, paper, and plastic fires is class A. This classification specifically targets common combustible materials that are solid in form, such as those derived from organic materials. When materials like wood or paper catch fire, they typically produce ash, which falls under this classification. Class A extinguishers are filled with materials like water or foam, which are effective at cooling the flames and eliminating the heat that sustains the fire. In contrast, other classes of fire extinguishers address different types of fires, such as flammable liquids, gases, or electrical fires. Therefore, class A is specifically tailored to handle the types of fires generated by solid combustibles like wood and paper, making it the appropriate choice for that scenario.
