Which class of fire extinguisher is suitable for fires involving wood, paper, some plastics, and textiles?

The correct response identifies Class A fire extinguishers as suitable for combating fires that involve ordinary combustibles such as wood, paper, textiles, and certain plastics. Class A fire extinguishers typically use water or foam to suppress fires, effectively cooling the burning material and removing the heat needed to sustain combustion.

This class is specifically designed to handle fires fueled by materials that leave an ash residue upon burning, which includes wood and paper. Using an appropriate extinguisher for this type of fire is crucial, as applying the wrong type could exacerbate the situation or create additional hazards.

Understanding the classifications of fire extinguishers helps ensure proper fire safety practices and effective response during an emergency.
