What type of fire requires a class K extinguisher?

• A. Electrical fires
• B. Cooking oils and fats
• C. Flammable liquids
• D. Gasoline fires

Answer: (B)

A Class K extinguisher is specifically designed to combat fires that involve cooking oils and fats, typically found in commercial kitchens where large quantities of cooking media such as vegetable oils, animal fats, and other cooking substances are used. These types of fires can burn at very high temperatures and require extinguishing agents that can effectively cool and smother the flames without spreading them. Class K extinguishers contain agents that can saponify the burning oils, creating a barrier that prevents the fire from reigniting. This is critical as cooking oil fires can quickly escalate if not addressed with the proper equipment. The other types of fires listed, such as those involving electrical components, flammable liquids, or gasoline, fall under different classification systems and require different types of extinguishing agents to ensure safety and effectiveness in firefighting. Therefore, only cooking oils and fats are effectively managed with a Class K extinguisher.
