Which type of fire cannot be extinguished with water?

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

Answer: (C)

The correct answer identifies the types of fires that cannot be extinguished with water. Class C fires involve electrical equipment, and water can conduct electricity, creating a risk of electric shock or further fire hazards. Using water on electrical fires is dangerous and can worsen the situation. Class K fires refer to fires that involve cooking oils and fats, typically found in commercial kitchens. Water can cause these types of fires to splatter and spread, creating an even larger blaze rather than extinguishing it. Class A fires, which involve ordinary combustibles like wood and paper, can safely be extinguished with water, as can Class B fires, which involve flammable liquids but require specific agents rather than water. Class D fires, involving combustible metals, also cannot be extinguished with water; however, the focus of the correct answer is on Class C and Class K fires due to the risks associated with water in those instances. Understanding these classifications is crucial for effectively and safely addressing fires in different scenarios.
