Which agent is appropriate for extinguishing electronic equipment fires?

The appropriate agent for extinguishing electronic equipment fires is carbon dioxide. This is primarily due to its ability to displace oxygen while being non-conductive, making it safe to use on live electrical equipment. When carbon dioxide is released from the extinguisher, it cools the flames and suffocates the fire by removing the oxygen that fuels it.

Using water on electronic fires can be extremely dangerous, as it is a good conductor of electricity and can lead to electrical shock or further complications in a live electrical setup. While foam and dry chemical agents are effective for many types of fires, they can leave residues that may damage sensitive electronic equipment or may not be safe to use in the presence of electrical currents. Therefore, carbon dioxide stands out as the most effective and safe choice for tackling fires involving electronic devices.
