Which pairing is correct?

Which pairing is correct?

• A. Class B Fire: Metals
• B. Class A Fire: Paper, Wood, Fabric
• C. Class C Fire: Wood
• D. Class D Fire: Paper

Answer: (B)

Fires are categorized by the type of fuel involved, which guides how we fight them. Ordinary combustibles like paper, wood, and fabric are Class A. Water-based extinguishers are particularly effective on these because they cool the material and stop the burning process. The pairing that lists paper, wood, and fabric as Class A matches this definition, so it is the correct choice. Metals belong to Class D, not Class B; wood is not a Class C material (C covers energized electrical equipment); and paper is not a Class D material (D covers combustible metals).
