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

The correct answer is that Class K fire extinguishers are specifically designed to combat kitchen grease fires. These extinguishers contain a wet chemical agent that effectively cools and extinguishes the flames from flammable cooking oils and fats, which are common in kitchen environments.

When a grease fire occurs, it can escalate quickly since cooking oils can reach high temperatures. Class K extinguishers not only suppress fires but also create a barrier between the fuel and the flames, helping to prevent re-ignition. This is crucial in kitchens where traditional extinguishing agents may not work effectively or could even exacerbate the situation.

In contrast, other types of fire extinguishers serve different purposes. Class C extinguishers are suited for electrical fires, Class B is typically used for flammable liquids and gases, and Class A is meant for ordinary combustibles like wood and paper. None of these options provide the specialized wet chemical approach needed for tackling kitchen grease fires effectively.
