Which statement accurately describes Class K extinguishers in kitchens?

• A. They are designed specifically for cooking oil and fat fires.
• B. They are designed for electrical fires only.
• C. They are suitable for all fire types.
• D. They require no maintenance.

Answer: (A)

Class K extinguishers are built for the big risk in kitchens: cooking oils and fats. They use a wet chemical agent that reacts with fats to saponify them, creating a soapy, cooling layer on the surface. This combination helps to smother the flames and prevent re-ignition specifically for oil and fat fires, which are common in commercial kitchens with fryers and woks.

That’s why the statement is the best fit: it captures the purpose of Class K extinguishers—tackling cooking-oil and fat fires with a specialized agent designed for that environment. They aren’t for electrical fires, they aren’t suitable for all fire types, and they do require maintenance and recharging after use or on a regular service schedule to ensure they work when needed.
