How to Put Out an Electrical Fire: A Step-by-Step Guide

Electrical fires can start suddenly and spread quickly, often without much warning. From overloaded power boards to faulty wiring, these fires are more common in homes and workplaces than many people realise.

Knowing what to do in those first few moments can make all the difference between a small, manageable incident and a serious disaster.

The most important thing is to stay calm and act fast while keeping yourself and others safe. In this step‑by‑step guide, we’ll walk you through how to recognise an electrical fire, how to tackle it safely and when to call for help.

By understanding these simple but vital steps, you’ll feel more confident and prepared if an emergency ever happens in your home or office.

Recognising an Electrical Fire

Spotting the signs of an electrical fire early can save you valuable time and keep everyone safer. Unlike other types of fires, an electrical fire often starts quietly and might not be obvious right away.

One of the first clues is usually a strong burning smell, like melting plastic or rubber. You might also notice outlets or switches that feel unusually hot to touch, sparks flying when you plug something in, or lights that flicker for no clear reason.

Another warning sign is smoke coming from appliances or power boards, even if you can’t see visible flames yet.

If you notice any of these signs, act quickly. Turn off and unplug the device, if it’s safe to do so, and cut the power at the circuit breaker. The sooner you recognise an electrical fire, the better chance you have of preventing it from spreading.

Stay Calm and Cut the Power

When you first realise there’s an electrical fire, your immediate reaction might be to panic, but staying calm is crucial. The very first step in controlling the situation is to cut off the power source feeding the fire.

If the flames are coming from a specific appliance and it’s safe to approach, unplug it carefully. Make sure you’re not standing in water or touching anything metal when you do this.

If unplugging isn’t possible or the fire is coming from the wiring itself, head straight to your home’s switchboard and shut off the main power supply. This step stops electricity from flowing and helps prevent the fire from spreading further.

Turning off the power also makes it much safer for you or anyone else trying to control the flames. Always remember: your safety comes first, so only cut the power if it’s safe to do so.

Never Use Water on an Electrical Fire

It’s natural to think of water when trying to put out a fire, but with electrical fires, that’s one of the most dangerous mistakes you can make.

Here’s why you should never use water and what to do instead:

• Water conducts electricity. Pouring water on an electrical fire can cause electric shock, putting you and anyone nearby in serious danger.
• It can spread the flames. Instead of putting the fire out, water can actually carry the current to other areas, making the situation worse.
• Appliances and wiring are high-risk. Even if the fire seems small, water can react unpredictably with live wires and components.
• Use safe alternatives. Reach for a Class C fire extinguisher or a fire blanket rather than water.
• Protect yourself first. Always cut the power and create a safe exit before attempting to control the fire.

Use the Right Fire Extinguisher

Once the power is cut, you may still need to tackle the flames, and that’s where the right fire extinguisher becomes essential. Not all extinguishers are safe for electrical fires.

You should only use a Class C fire extinguisher (or one specifically marked as safe for electrical fires). These extinguishers are designed to put out flames without conducting electricity, keeping you safer while you work to control the situation.

Before using it, quickly remind yourself of the PASS method: Pull the pin, Aim the nozzle at the base of the fire, Squeeze the handle slowly and Sweep from side to side. Stand a safe distance away and keep your exit path clear in case the fire grows.

Never use water or foam extinguishers, as these can conduct electricity and make things worse. Having the correct extinguisher nearby could mean the difference between a minor scare and serious damage.

Smother Small Flames Safely

If you’re dealing with a small electrical fire that hasn’t spread, smothering the flames can be an effective way to stop it. The goal is to cut off the fire’s oxygen supply so it can’t keep burning.

A fire blanket is ideal for this because it’s made from fire‑resistant material that won’t catch alight. Gently place the blanket over the flames – don’t throw it – making sure it completely covers the fire.

If you don’t have a fire blanket, you can use a heavy, non‑flammable item like a woollen blanket or a thick coat as a last resort. Avoid using anything synthetic, as it can melt and make the fire worse.

Always keep your hands and face protected, and make sure you have a clear path to leave if things get out of control. Smothering small flames quickly can stop an electrical fire before it grows into something far more dangerous.

Evacuate and Call Emergency Services

If the fire is growing or you can’t control it safely, it’s time to step back and get everyone out. Your safety is always the top priority.

Here’s what to do:

• Leave immediately if the fire spreads. Don’t waste time gathering belongings – focus on getting everyone to safety.
• Alert others in the building. Shout or knock on doors as you leave to make sure everyone knows there’s a fire.
• Use the safest exit. Avoid areas filled with smoke and never use an elevator during a fire.
• Call emergency services (000) right away. Dial your local emergency number as soon as you’re in a safe place and clearly explain the situation.
• Stay outside and wait for help. Do not re‑enter the building, even if you think the fire is out. Let the firefighters handle the rest.

Preventing Future Electrical Fires

Taking steps to prevent electrical fires is just as important as knowing how to put them out. With a few simple habits and regular checks, you can greatly reduce your risk:

• Avoid overloading outlets and power boards. Spread out your appliances to prevent overheating and excess current draw.
• Inspect cords and plugs regularly. Replace any that are frayed, cracked, or damaged before they become a hazard.
• Keep flammables away from appliances. Items like paper, cloth, or cleaning products should never be stored near heat‑producing devices.
• Use quality electrical products. Choose appliances and extension leads that meet safety standards and avoid cheap, untested items.
• Schedule regular electrical inspections. A licensed electrician can spot issues in your wiring before they turn into serious problems.
• Install safety devices. Residual current devices (RCDs) and smoke alarms add extra layers of protection for your home.

Be Prepared for an Electrical Fire

Electrical fires can be frightening but knowing what to do makes a huge difference. By recognising the early warning signs, staying calm, and cutting the power, you give yourself the best chance to act quickly and safely.

Always remember to use the right tools, like a Class C fire extinguisher or a fire blanket and never attempt to douse an electrical fire with water. If the flames grow beyond your control, evacuate immediately and call emergency services without hesitation.

Taking preventative steps – such as regular inspections, avoiding overloaded outlets, and keeping cords in good condition – will also reduce the risk of a fire starting in the first place. With these tips in mind, you’ll be far better prepared to protect your home, your belongings and, most importantly, yourself. Stay safe.
