Final answer:
Wet Chemical Stored-Pressure Extinguishers are intended for Class K fires involving cooking materials such as fats, grease, and oils.
Step-by-step explanation:
Wet Chemical Stored-Pressure Extinguishers are specifically designed to combat Class K fires. These types of fires involve cooking materials such as fats, grease, and oils that are typically found in commercial kitchens. The wet chemical extinguishing agent works by forming a soapy foam layer over the burning oil, which cools and seals the surface to prevent re-ignition. This foam is an example of a fluorinated solution able to spread across the burning surface to effectively extinguish the fire.
