What is the best type of extinguisher to use dousing an electrical fire?

Class A
Class B
Class C
Class D

The correct answer is: Class C

Class C fire extinguishers are designed specifically for tackling electrical fires. Electrical fires involve energized electrical equipment such as wiring, circuit breakers, and appliances. They can be caused by short-circuits, overloading, or overheating. Class C fire extinguishers use non-conductive substances to combat the fire. This is extremely important because using a fire extinguisher that conducts electricity can increase the risk of electrocution and isn't effective in putting out the fire. For this reason, when it comes to electrical fires, a Class C fire extinguisher is the best and safest choice. It's always crucial to check the classification of a fire extinguisher to ensure it's suitable for the type of fire at hand.
