Explanation

Electrical fires (classified as Class C in the US) must be fought with non-water based extinguishers, such as CO2 or dry chemical types. Water conducts electricity, so using water or water-based extinguishers on an electrical fire creates a serious risk of electrocution. Overhead sprinkler systems are also water-based and equally dangerous. Class B extinguishers are designed for flammable liquid fires, not electrical fires.
