Basic Corrections Officer: Certification Practice

Which type of extinguisher is most effective for electrical fires?

1. Class A

2. Class B

3. Class C

4. Class D

The correct answer is: Class C

Class C fire extinguishers are specifically designed to address electrical fires. These types of fires occur when electricity is involved, and using water or certain other extinguishing agents can pose serious hazards, including electrocution. Class C extinguishers use non-conductive agents to safely put out electrical fires. These agents often include carbon dioxide or dry chemical powders, which do not conduct electricity and effectively suffocate the flames. In contrast, Class A extinguishers are meant for ordinary combustible materials like wood and paper, while Class B extinguishers target flammable liquids such as gasoline or oil. Class D extinguishers are intended for use on combustible metals, which are a different category altogether. Each class of fire extinguisher is tailored to combat specific types of fires based on the material involved, making Class C the appropriate choice for electrical fires.
