What Is Class E Fires? Understanding Electrical Fires

  • October 31, 2025

You know very well how we all use electricity every day — at home, in offices, in factories. But sometimes, that same electricity can turn dangerous. A small spark, a broken wire, or a short circuit is enough to start a fire. That kind of fire is called a Class E fire.

So, let’s understand what it really means and how you can stay safe.

What Is Class E Fire?

A Class E Fire happens when something electrical catches fire. It could be a switchboard, computer, washing machine, or even a heavy motor in a factory. Basically, any fire that starts because of electricity comes under this type.

You must not pour water on it — that’s one of the worst mistakes people make. Water and electricity together can give a shock. So, you need the right kind of fire extinguisher, which is specially made for these fires.

Common Causes of Electrical Fires

In order to understand, there are so many small reasons that lead to electrical fires, like:

  • Loose wires or damaged cables
  • Overloaded plugs and sockets
  • Short circuits
  • Old or broken electrical machines
  • Poor maintenance of panels and wiring

Even a small spark can turn into a big problem if it goes unnoticed. That’s why checking your electrical setup every few months is very important for everyone.

Why Class E Fires Are So Dangerous?

Electrical fires are risky because you don’t know where the current is flowing. You can’t see electricity, but it’s there. And if you go near the current, you might also get hurt badly.

Also, once the fire starts, it spreads fast through wires and machines. The smoke, on the other hand, is also harmful because burning plastic and wires release toxic gases. That’s why you must stay away until the power is cut off.

When Should I Use a Fire Extinguisher on a Class E Fire?

If you ever face an electrical fire, the first thing you should do is turn off the main power. Only then should you use a Class E fire extinguisher. If the fire looks small and you’re confident, use the extinguisher carefully. But if it’s already spreading, don’t take any risk — step out and call the fire service immediately.

Which Extinguisher Should You Use for Class E Fires?

There are two main types of extinguishers used for electrical fires.

  • CO2 Fire Extinguisher 

The CO2 fire extinguisher is the safest for electrical fires, did you know? And it releases carbon dioxide gas, which removes oxygen from around the fire. Without oxygen, the fire stops. It doesn’t leave water, foam, or powder behind, so your machines and computers stay safe. 

  • Dry Powder Extinguisher

A dry powder extinguisher can also put out an electrical fire, but it leaves a lot of dust. That dust can spoil machines and make cleaning messy. So, it’s only good if you don’t have a CO2 extinguisher nearby.
