Which type of fire extinguisher is specifically designed for grease fires?

A Class K fire extinguisher is specifically designed for grease fires, particularly those that involve cooking oils and fats. These types of fires can occur in commercial kitchens, restaurants, or any environment where cooking is performed. Class K extinguishers contain agents that are effective in cooling and saponifying the burning grease, which is crucial for safely extinguishing the fire without causing flare-ups.

In contrast, other classes of extinguishers are intended for different types of fires. For instance, Class A extinguishers are used for ordinary combustible materials like wood, paper, and textiles. Class B extinguishers address flammable liquids such as gasoline or solvents, while Class C extinguishers are meant for electrical fires. Therefore, the unique formulation of those used in Class K extinguishers makes them the appropriate choice for tackling grease fires effectively and safely.
