What type of fire extinguisher should be used for a fire with live electricity present?

Using a Class C fire extinguisher is essential for fighting fires that involve live electrical equipment. This type of extinguisher is specifically designed to handle fires that are fed by electrical energy sources, ensuring that the extinguishing agent will not conduct electricity and further create a dangerous situation.

Class C extinguishers typically use non-conductive agents such as carbon dioxide or dry chemical powders, which are effective in smothering the fire without posing a risk of electrical shock or further ignition. This makes them suitable and safe for use in environments where live electricity is present, such as in offices or industrial settings with electrical devices.

In contrast, other classes of extinguishers are not appropriate for dealing with electrical fires. Class A extinguishers are meant for ordinary combustibles like wood and paper, Class B extinguishers are for flammable liquids and gases, and Class D extinguishers are for combustible metals. Each of these would not only be ineffective on electrical fires but could also create additional hazards if used incorrectly. Understanding the proper type of extinguisher for specific fire situations is crucial for safety.
