Which class of fire involves solids?

• A. Class A Fire
• B. Class B Fire
• C. Class C Fire
• D. Class D Fire

Answer: (A)

Fires involving solids are categorized as Class A. This group covers ordinary combustibles like wood, paper, cloth, and many textiles. They burn in a way that heat removal stops the reaction, and water is effective because it absorbs a lot of heat, cooling the material and often helping to smother the flame. The other classes handle different fuels: liquids (Class B), energized electrical equipment (Class C), and reactive metals (Class D). So, for solids, Class A is the correct classification.
