Wet chemical extinguishers are designed for which fire class?

Explanation:
Wet chemical extinguishers are designed for fires involving cooking oils and fats, which are Class K fires. They contain potassium acetate that reacts with the oil to form a soapy, viscous layer on the surface. This layer blankets the fuel, cools it, and prevents contact with air, stopping the fire from reigniting. They aren’t intended for ordinary combustibles, flammable liquids, or electrical fires, making Class K the specific match for cooking-oil scenarios.
