Which statement describes the intended use of Class K extinguishers?

• A. For large, uncontrolled fires
• B. For small to moderate oil/fat fires in kitchens
• C. For electrical panel fires only
• D. For all types of fires equally

Answer: (B)

Class K extinguishers are specifically designed for fires involving cooking oils and fats, which are common in commercial kitchens. They use a wet chemical agent that saponifies fats, turning them into a soapy layer that cools the oil and blankets the fire, helping to prevent re-ignition. Because of this specialized action, they’re best suited for small to moderate oil/fat fires in kitchens. They’re not intended for large, uncontrolled fires, nor are they meant for electrical panel fires or fires involving other materials, which is why the option describing use for small to moderate oil/fat fires in kitchens is the correct choice.
