SOLUTION

The suitable extinguisher for extinguishing a live electrical fire is CO2 fire extinguisher

• Effectiveness on Electrical Fires: CO2 fire extinguishers are specifically designed for use on electrical fires because they do not conduct electricity, making them safe to use on live electrical equipment. They work by displacing oxygen around the fire, effectively smothering it and preventing re-ignition.
• Advantages of CO2 Extinguishers:
  • No Residue: CO2 leaves no residue, which means it won’t damage sensitive electronic equipment or create a mess after use.
  • Cooling Effect: While they do not cool the fire as effectively as water, they do help to lower the temperature of the burning material by removing heat from the combustion triangle
