What does the red-labelled extinguisher put out?

• A. Electrical fires
• B. Wood, Paper, Fabrics
• C. Cooking oils/Fats
• D. Flammable liquids

Answer: (B)

Fires are categorized by the fuel involved, and extinguishers are matched to those fuel types. A red-labelled extinguisher is for ordinary combustibles—wood, paper, and fabrics. It works by delivering a cooling effect: the water absorbs heat from the flames and the fuel, bringing temperatures below the material’s ignition point so the fire can’t continue. That cooling action makes it the best fit for those fuels. It isn’t designed for electrical fires, because water conducts electricity and can cause shocks; it isn’t appropriate for cooking oils or fats, which require a different agent to avoid splashing and spreading the fire; and it isn’t suitable for flammable liquids or metal fires, which need other extinguishing approaches. Always follow the extinguisher label and safety guidelines.
