What is the name of the chemical used to suppress electrical fires?

The chemical used to suppress electrical fires is Carbon Dioxide (CO2). This is primarily because CO2 effectively displaces the oxygen in the vicinity of the fire, thereby suffocating it without leaving any residue or causing additional damage to electrical equipment.

Carbon Dioxide is non-conductive, making it safe for use around energized electrical systems, unlike water, which is a conductor and can result in electrical shock or further complications in an electrical fire emergency. Additionally, Sodium Bicarbonate can be effective for small, specific types of fires, such as grease fires, but is not the standard recommendation for electrical fires. Foam agents are typically used for flammable liquids and may not be suitable for electrical hazards. Therefore, CO2 stands out as the most appropriate and effective choice for extinguishing electrical fires.
