What Type of Fire Extinguisher Is Used for Electrical Fires

When it comes to fire safety, knowing which fire extinguisher to use is very important. Not all fire extinguishers are made for the same type of fire. Using the wrong one can be dangerous. Electrical fires, in particular, need special attention because they involve electricity, which can cause shock or make a fire worse. In this article, we will talk about the right type of fire extinguisher to use for electrical fires and how it works.

What Is an Electrical Fire?

An electrical fire happens when electrical equipment or wiring catches fire. This can be caused by:

  • Overloaded circuits

  • Damaged wires

  • Faulty appliances

  • Short circuits

  • Overheating of devices

Electrical fires are common in homes, offices, and industrial places where there are many machines and devices. These fires can spread quickly and are very dangerous if not handled properly.

Why You Can’t Use Water on Electrical Fires

One of the biggest mistakes people make during an electrical fire is trying to put it out with water. This is very risky. Water is a good conductor of electricity, so it can cause electric shock. If you pour water on an electrical fire, the current can travel through the water and harm anyone nearby. This is why special fire extinguishers are made to deal with such situations safely.

Fire Extinguisher Classes

Before understanding which one to use, let’s learn the classes of fire extinguishers:

  • Class A: For fires involving paper, wood, cloth, and other ordinary materials

  • Class B: For flammable liquids like gasoline, oil, and paint

  • Class C: For electrical fires (the focus of this article)

  • Class D: For metal fires, like magnesium or aluminum

  • Class K: For kitchen fires involving cooking oils and fats

For electrical fires, Class C fire extinguishers are the right choice.

Types of Fire Extinguishers Safe for Electrical Fires

There are several types of fire extinguishers that can safely be used on electrical fires. Let’s go over the main ones:

1. CO2 (Carbon Dioxide) Fire Extinguishers

  • These are commonly used for electrical fires.

  • CO2 extinguishers work by removing oxygen, which fire needs to burn.

  • They also cool down the fire.

  • Since CO2 is a gas, it leaves no residue, making it perfect for computers, printers, and other sensitive electronics.

  • These extinguishers have a horn-like nozzle.

2. Dry Chemical Fire Extinguishers (ABC or BC Type)

  • The ABC dry chemical extinguisher can be used for Class A, B, and C fires.

  • It works by coating the fire with a layer of powder that cuts off the oxygen supply.

  • For electrical fires, make sure the extinguisher is rated Class C.

  • Though effective, it leaves behind powder that may damage electronic devices.

3. Clean Agent Fire Extinguishers

  • These use gases like Halotron or FE-36 that put out fires without harming electronics.

  • They don’t leave a mess like dry chemicals.

  • Clean agent extinguishers are perfect for server rooms, labs, and areas with lots of electrical equipment.

  • They are more expensive but safer for delicate machines.

How to Use a Fire Extinguisher (PASS Method)

If you need to use a fire extinguisher, remember the PASS technique:

  • P – Pull the pin

  • A – Aim the nozzle at the base of the fire

  • S – Squeeze the handle

  • S – Sweep side to side

Always keep your distance and never turn your back on the fire.

Safety Tips for Electrical Fires

  • Turn off the power source if it is safe to do so.

  • Never use water or foam extinguishers on electrical fires.

  • Keep CO2 or dry chemical extinguishers near electrical panels and computer rooms.

  • Call the fire department even if the fire seems small.

  • Get your fire extinguisher inspected regularly.

Conclusion

Electrical fires are dangerous and must be handled with care. The right fire extinguisher can save lives and property. CO2, dry chemical, and clean agent extinguishers are all safe choices for electrical fires, as long as they are rated Class C. Always check the label before using one. Having the correct extinguisher and knowing how to use it can make a big difference during an emergency. Stay safe and be prepared!
