Practice question

What type of fire extinguisher is used for electrical fires?

  1. Class A
  2. Class B
  3. Class C
  4. Class D

Answer: C — Class C

A Class C fire extinguisher is specifically designed for electrical fires. These extinguishers use non-conductive agents to put out fires that involve energized electrical equipment, such as wiring, circuit breakers, and appliances. It is crucial to use the appropriate type of extinguisher on electrical fires to avoid the risk of electric shock or furthering the fire by using a conductive media. Class C extinguishers typically contain agents like carbon dioxide (CO2) or dry chemical powders that effectively extinguish flames without conducting electricity, making them safe for use on electrical sources. Understanding the classification of fire extinguishers is essential in ensuring safety during firefighting efforts, particularly regarding how different types react to various fire sources.
