Which type of fire extinguisher is most suitable for electrical fires?

The CO2 extinguisher is the most suitable choice for electrical fires due to its properties that effectively tackle such hazards. Carbon dioxide extinguishers work by displacing oxygen and smothering the fire, which is particularly effective for fires involving electrical equipment. Since electrical fires can occur in environments containing live wires or equipment, using a CO2 extinguisher prevents the risk of conduction and avoids the potential for further electrical issues, as CO2 is non-conductive.

Additionally, CO2 extinguishers leave no residue, making them ideal for sensitive electronic devices since they do not damage or compromise the integrity of the equipment involved. Their ability to quickly extinguish flames without any water or foam assures safety against adding to the electrical hazard.

For situations involving electrical fires, it is vital to choose an extinguisher that not only effectively mitigates the fire but also maintains safety when it comes to electrical conductance and potential damage from extinguishing agents.
