Which class of fire consists of rubbish and wood?

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

Answer: (A)

Fires are categorized by the type of fuel involved. Rubbish and wood are solid, ordinary combustibles that burn and leave ash, which places them in Class A. This class covers common materials like paper, cardboard, wood, and rubbish, and is typically addressed with cooling methods such as water to remove heat from the fuel. The other classes involve different fuels: Class B is for flammable liquids, Class C for live electrical equipment, and Class D for certain metal fires. So rubbish and wood naturally fall under Class A.
