Which class of fire involves energized electrical equipment?

The classification of fires is based on the materials that are burning, and each class has specific characteristics and appropriate extinguishing agents. Class C fires specifically involve energized electrical equipment, which distinguishes them from other classes.

When dealing with Class C fires, it’s crucial to remember that water may conduct electricity and potentially cause harm, making water-based extinguishing agents inappropriate for this type of fire. Instead, non-conductive extinguishing agents, such as carbon dioxide or dry chemical extinguishers, are used to safely put out these fires.

The other classes of fire involve different types of materials: Class A deals with ordinary combustibles like wood and paper, Class B involves flammable liquids and gases, and Class K specifically addresses cooking oils and fats. Understanding these distinctions is essential for selecting the correct extinguishing methods and ensuring safety around electrical equipment during a fire situation.
