Which class of fire extinguishers should you use on electrically energized fires?

Answer :

Final answer:

For fires involving electrical equipment, use a Class C fire extinguisher designed for such hazards. Class C extinguishers, such as those using carbon dioxide or dry chemical agents, help to manage fires without the risk of electric shock. Always prioritize safety by ensuring electrical sources are de-energized when possible.


Explanation:

Choosing the Right Fire Extinguisher for Electrically Energized Fires


When dealing with fires that involve electrical equipment, it is crucial to use the appropriate class of fire extinguisher to ensure safety and effectiveness. For electrically energized fires, you should use a Class C fire extinguisher. This type of extinguisher is specifically designed for fires involving electrical equipment such as wiring, circuit breakers, and appliances.


Class C extinguishers typically use non-conductive agents, such as carbon dioxide (CO2) or dry chemical powder, which do not pose a risk of electric shock. Here are some important points regarding Class C fire extinguishers:



  1. Carbon Dioxide (CO2) extinguishers are effective for small electrical fires because they displace oxygen and cool the flames without leaving a residue.

  2. Dry Chemical extinguishers, specifically those labeled as ABC, are multipurpose extinguishers that work on Class A, B, and C fires; however, they can leave a residue and may require cleanup.

  3. Always ensure that the electrical source is de-energized before using any fire extinguisher on an electrical fire, if it is safe to do so.


By using a Class C extinguisher, you ensure a safer approach to handling fires involving electrical components.
