What can you use to put out a Class C fire?

Water
Gas
Foam
Baking soda

The correct answer is: Baking soda

To effectively put out a Class C fire, which involves energized electrical equipment, using a non-conductive extinguishing agent is essential to ensure safety. Baking soda can act as an effective method for this type of fire because it can smother the flames by releasing carbon dioxide when heated, thus depriving the fire of oxygen. This property makes it a suitable choice since it does not conduct electricity, reducing the risk of electrical shock. In contrast, water is highly conductive and can pose a serious hazard when used on electrical fires, as it may lead to electrocution. Gas could also potentially fuel the fire rather than extinguish it. Foam is more appropriate for Class A or B fires and may not effectively address the situation with energized electrical equipment. Therefore, using baking soda is a safe and effective method to extinguish a Class C fire.
