Common Safety Orientation (CSO) Practice Test

Question: 1 / 400

Which type of fire extinguisher is suited for electrical fires?

Class A

Class B

Class C

The appropriate type of fire extinguisher for electrical fires is Class C. This type of extinguisher is specifically designed to combat fires that involve energized electrical equipment, such as wiring, circuits, or appliances. Using a Class C extinguisher is safe because it utilizes non-conductive agents that effectively extinguish flames without posing a risk of electrocution.

Class A extinguishers are meant for ordinary combustibles like wood, paper, and cloth, while Class B extinguishers are suitable for flammable liquids such as gasoline and oils. Class D extinguishers are specifically intended for fires involving combustible metals, which are not relevant in the context of electrical fires. Thus, Class C is the clear choice for effectively and safely addressing electrical fire hazards.
