Why cant carbon dioxide be used on an electrical fire?

Carbon dioxide (CO2) is often used to extinguish electrical fires because it effectively displaces oxygen, which is essential for combustion. However, it is important to ensure that the electrical source is completely de-energized before using CO2, as applying it directly to live electrical equipment can pose a risk of electric shock or further igniting the fire. Additionally, CO2 may not be effective in suppressing fires involving certain materials that can continue to burn without an adequate oxygen supply. Always prioritize safety and use appropriate extinguishing methods based on the specific fire scenario.
