Which fire class should never be extinguished with water?

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

Answer: (C)

Class C fires involve electrical equipment and energized electrical systems. Water is a conductor of electricity and using it to extinguish a Class C fire poses a significant risk of electrocution to the person attempting to extinguish the fire as well as potentially spreading the fire further if the water comes into contact with live electrical sources. It's important to use appropriate agents for Class C fires, such as carbon dioxide or dry chemical extinguishers, which do not conduct electricity and can safely suppress the fire without causing additional hazards. Understanding the nature of the fire type is crucial for safety and effectiveness during firefighting efforts.
