What type of fire extinguisher is best for grease fires?

A Class K extinguisher is specifically designed to combat fires that involve cooking oils and greases, which are common in kitchens and food preparation areas. These extinguishers contain a wet chemical agent that can effectively cool and saponify the burning grease, reducing the risk of re-ignition and allowing for a safe and effective extinguishing process.

The other types of extinguishers serve different purposes. Class A extinguishers are suitable for ordinary combustibles like wood, paper, and textiles, while Class B extinguishers are intended for flammable liquids such as gasoline and oil. Class C extinguishers are used for electrical fires. Using these extinguishers on a grease fire can be ineffective and potentially dangerous, as they may not adequately address the unique characteristics of burning cooking oils.
