Which statement about Class K extinguishers is accurate?

Explanation:
Class K extinguishers are designed specifically for commercial kitchen oil and fat fires. They discharge a wet chemical agent that reacts with cooking oils to form a soapy layer, which cools and smothers the fire. Because of this targeted action, they are not suitable for every kind of fire. Using them on non-oil fires or outside a kitchen can be ineffective or unsafe. Always follow the label instructions for use and maintenance, and recognize that proper training helps you deploy them correctly—aim at the base of the fire and sweep, and know when to evacuate and call for help. They are not identical to Class A extinguishers, which are for ordinary combustibles like paper and wood, and they’re not interchangeable with other classes.
