Which fire suppression agent is typically used to fight electrical fires?

Carbon Dioxide (CO2) is the appropriate fire suppression agent for fighting electrical fires because it works by displacing the oxygen that the fire needs to continue burning. When CO2 is discharged, it creates a blanket of gas that suffocates the flames while also cooling down the area, thereby preventing further ignition.

One of the key advantages of CO2 is that it does not conduct electricity, making it safe to use on live electrical equipment. Additionally, it leaves no residue, which is crucial when dealing with electronics where any residue could cause damage or malfunction.

In contrast, using water on electrical fires can be extremely dangerous as water is a conductor of electricity and can create electrocution hazards. AFFF foam and dry chemical powder can also be effective for various fire types, but they are not specifically suited for electrical fires due to potential residues and properties that may not be suitable for electrical equipment. Thus, CO2 is the preferred choice in these situations for safety and effectiveness.
