Multiple Choice

Which extinguisher class should be used on a box of laser printer paper?

A box of laser printer paper involves ordinary combustibles like paper and cardboard, so the extinguisher designed for those fuels is the best fit. Extinguishers for ordinary combustibles work by cooling the burning material and preventing reignition, which is ideal for a paper fire. Extinguishers intended for flammable liquids are for fuels such as solvents and oils, which behave differently and require a different approach. Fires involving energized electrical equipment call for a nonconductive, electrical-safe option, and fires from combustible metals need a specialized agent to handle metal reactions. So in this scenario, choose the extinguisher rated for ordinary combustibles, since paper fires are best managed with that type. If other materials or hazards were present (solvents, live electrical equipment, or metal fuels), the appropriate class would differ.
