Households are using more electricity than ever before due to the number of technological devices in the home. This means we are more exposed to electrical hazards, which can cause serious harm like house fires and electrical injuries.

Electrical injuries can come from many different sources but generally fall into one of three categories:

- Burns
- Electric shock
- Electrocution

That’s why it’s important to know what you can do to protect yourself and your home from electrical hazards, and avoid these types of accidents or injuries altogether.

Key takeaways
## The short version

- **Watch for signs of faulty wiring:** flickering lights, hot outlets or burning smells can indicate serious electrical issues. Call a professional immediately.
- **Avoid overloading power outlets:** plugging too many devices into one outlet can cause overheating, circuit trips or even house fires.
- **Replace old or damaged appliances:** frayed cords and worn-out devices increase the risk of electric shock and should be repaired or replaced promptly.
- **Keep electricity away from water:** never use appliances near water, and always switch off power immediately if contact occurs.
- **Protect children from hazards:** use outlet covers and teach kids to stay away from wires and electrical devices.
- **Act early to prevent accidents:** regular checks and proactive maintenance can significantly reduce the risk of electrical injuries and fires.

![Top 5 electrical hazards in the home and how to avoid them](https://russoelectrical.com.au/wp-content/uploads/2026/03/Electrical-Hazards-blog-OG-1024x512.webp)
## 1Faulty wiring

Faulty wiring is one of the leading electrical hazards in the home. It can cause house fires, power surges and other electrical hazards, so it’s crucial that you know the warning signs.

Warning signs include:

- **Buzzing or flickering lights:** if your lights are flickering and dimming, it could be a sign of faulty wiring, especially if they dim or flicker when using multiple appliances.
- **Hot power outlets:** if your power outlets are hot or vibrating, that is another sign of faulty wiring.
- **Burning smells:** if you can smell burning, it is a sign that heat has already damaged your wiring.

**Notice any of these signs,** or not sure if your wiring is in good shape? Don’t hesitate to [contact a professional electrician](https://russoelectrical.com.au/contact-us/) to double-check everything is working correctly and that there is no immediate danger. Problems at the switchboard are covered by our [switchboard support service](https://russoelectrical.com.au/services/switchboard-support/).
## 2Overloaded power outlets

Most homes have extension cords and outlets with multiple appliances and devices plugged into them. Every power outlet has a specific load that it can safely handle. If this load is exceeded, it can cause the circuit breaker to trip, which shuts down the power supply.

If there is no circuit breaker, overloaded power outlets can become a real fire hazard. They can overheat, which can cause the wires to melt and lead to a fire. Older homes without modern protection may need a [switchboard upgrade](https://russoelectrical.com.au/services/switchboard-upgrade/).

Signs your power outlets have become overloaded:

- Your power outlets making a buzzing noise
- Power outlets becoming hot
- Power outlets having a burning smell
- Scorched power outlets

**To avoid this fire hazard,** don’t overload your power outlets, and switch them off in the event of a storm or when you go away on holiday. Adding lots of new appliances?

## 3Old and damaged appliances

Old and damaged appliances are a common electrical hazard, even if they are working normally. Always check your old appliances for frayed or cracked power cords, and replace them when they reach a certain age.

**Don’t forget chargers:** phone, tablet and laptop chargers should be checked regularly, as they are used extensively and highly prone to damage. Replace them when the cords become damaged.
## 4Using appliances and devices near water

Appliances, devices and water do not mix and should be kept at a safe distance from each other, as water is a good conductor of electricity. The obvious solution to this hazard is to keep appliances and devices a safe distance away from water.

**If an appliance or device comes into contact with water,** act quickly and turn off the power source to avoid electrocution and electric shock.
## 5Children

Young children are often exploring and getting into things they shouldn’t, and electrical appliances and power outlets are no exception. Keep children safe by making sure all electrical appliances and power points in your home have protective covers.

Stop children from being seriously harmed or causing an electrical accident by teaching them never to remove a protective cover or go near electric wires or outlets. Make it clear that doing so could expose them to deadly voltage levels or electric shocks.

**More tips for parents:** read our [parent’s guide to child electrical safety at home](https://russoelectrical.com.au/child-electrical-safety-at-home/).
## Don’t fix it yourself

If you notice a problem with your electrical appliances, power outlets, power cords or light fittings, do *not* try to fix the problem yourself. Contact an electrician straight away. In an emergency, follow our guide to [what to do in an electrical emergency](https://russoelectrical.com.au/5-things-you-can-do-in-an-electrical-emergency/).

## Common electrical hazards at home: FAQs

What are the most common electrical hazards at home?
The most common electrical hazards include faulty wiring, overloaded power outlets, damaged appliances, using devices near water, and unsafe interactions by children.

These hazards can lead to electric shock, burns or even house fires if not properly managed.

What are the warning signs of faulty wiring?
Signs of faulty wiring include flickering or dimming lights, hot or vibrating power outlets, and burning smells.

If you notice any of these, contact a licensed electrician immediately to prevent serious hazards.

What happens when power outlets are overloaded?
Overloaded outlets can cause circuit breakers to trip or, in worse cases, lead to overheating, melting wires and electrical fires.

Warning signs include buzzing sounds, heat, burning smells or scorch marks on outlets.

Are old or damaged appliances dangerous?
Yes. Appliances with frayed cords, cracked wires or wear and tear can become serious electrical hazards.

Chargers and frequently used devices should be checked regularly and replaced if damaged.

Why should electrical appliances be kept away from water?
Water is a strong conductor of electricity, making it extremely dangerous when combined with electrical devices.

If an appliance comes into contact with water, turn off the power source immediately to prevent electrocution or shock.

How can children be protected from electrical hazards?
Install protective covers on outlets, keep appliances out of reach, and teach children not to touch electrical wires or devices.

Education and supervision are key to preventing accidents involving electricity.

How can I reduce the risk of electrical hazards at home?
Regularly inspect wiring and appliances, avoid overloading outlets, keep devices away from water, and install safety features like outlet covers and circuit breakers.
