What type of fire extinguisher is needed for electrical equipment fires?

The correct type of fire extinguisher for electrical equipment fires is a dry chemical extinguisher. This type of extinguisher is effective because it uses a powder that can interrupt the chemical reaction of a fire, and it is non-conductive, making it safe to use on live electrical equipment.

When dealing with fire involving electrical components, it is crucial to avoid any extinguishers that can conduct electricity, such as water or foam extinguishers, as they pose significant safety risks. Water can create a shock hazard when applied to energized equipment, and foam may also be conductive. Carbon dioxide extinguishers are also a good option; however, they primarily displace oxygen rather than interrupt the chemical reaction, which can be less effective in some situations compared to dry chemical extinguishers.
