What is the classification for fires in kitchen and cooking equipment?

• A. Class A
• B. Class B
• C. Class K
• D. Class C

Answer: (C)

Fires in kitchens and cooking equipment are categorized as Class K. This category covers fires involving cooking media, specifically fats and oils used for frying and cooking. These substances burn at high temperatures and behave differently from ordinary combustibles or flammable liquids, so they require a distinct approach. Water on a cooking-oil fire is dangerous because it can cause the oil to splatter and the fire to flare up; instead, a Class K extinguishing agent is used. Wet chemical agents (such as potassium acetate) saponify the fat, forming a soapy layer that cools and separates the oil from the air, helping to smother and suppress the fire. In kitchens, you’ll often see specialized extinguishers and hood suppression designed for this hazard. For reference, other classes cover different hazards: ordinary combustibles (wood, paper) are Class A, flammable liquids (gasoline, solvents) are Class B, and electrical equipment is Class C. The unique hazard in cooking environments is the cooking fats and oils, so the appropriate classification is Class K.
