Electrical Safety Tips During a Cyclone: Follow Our Complete Guide

When a cyclone is on the way, most people think about securing windows and stocking up on supplies − but don’t forget about electrical safety.

If you’re in an area that is subjected to cyclones − such as the coastal regions of Western Australia and northern Queensland − this is vital information.

Strong winds, heavy rain and flooding can all wreak havoc on your home’s wiring, powerpoints and appliances. That’s why it’s important to take some simple precautions before, during, and after the storm to keep you and your family safe.

From switching off your power at the mains to knowing what to do if a powerline comes down and when to call an emergency electrician, a little knowledge can go a long way in an emergency.

In this guide, we’ll walk you through practical electrical safety tips to help protect your home and avoid dangerous accidents during a cyclone. Stay safe, stay calm − and be prepared for whatever the weather throws your way.

Turn Off Power at the Main Switch Pre-Storm

One of the most important things you can do before a cyclone arrives is to switch off the power at your main switchboard.

This helps prevent electrical fires, appliance damage, or even electrocution caused by power surges, flooding or downed lines. It’s a quick step that can make a huge difference to your safety.

You’ll usually find the main switch in your fuse box or meter box − often located outside the home. Simply flip the main circuit breaker to the “off” position. If you’re not sure how to do this, check ahead of time or ask an electrician for guidance.

Turning off the power is especially crucial if your area is at risk of flooding. Water and electricity are a deadly mix, so it’s better to be cautious.

Once the storm passes, only restore power if you’re certain it’s safe − or let a professional handle it.

Unplug All Electrical Appliances

Before a cyclone hits, one of the simplest yet most effective things you can do is unplug your electrical appliances. Power surges, lightning strikes or water exposure can cause serious damage – or even fires.

Here’s why unplugging matters and what to keep in mind:

• Prevent damage from power surges – Storms often cause voltage spikes that can fry your electronics in an instant.
• Avoid fire risks – Faulty or wet wiring can short-circuit and potentially ignite a fire if appliances are still plugged in.
• Protect expensive items – Unplug TVs, computers, fridges, air conditioners and other valuable devices.
• Reduce shock risk post-storm – If water gets into sockets, unplugged devices lower the chance of electric shock when power returns.
• Don’t forget chargers – Phone and laptop chargers left plugged in can be just as vulnerable.

It only takes a few minutes but could save you a big headache – and a big bill – later on.

Keep Electrical Devices Elevated and Dry

When a cyclone is on the horizon, there’s always a risk of water entering your home − especially in low-lying areas. That’s why it’s smart to move electrical appliances and devices off the floor and onto higher ground.

Items like power boards, computers, TVs and phone chargers should be unplugged and placed somewhere dry and elevated, like a high shelf or benchtop.

Even small amounts of water can damage electronics or create shock hazards, so don’t take any chances. If you have extension cords or power boards lying around, coil them up and keep them well away from windows, doors and potential flood zones.

It’s also a good idea to use waterproof covers for important equipment if you have them on hand. Taking these extra steps can help protect your valuables and reduce the risk of electrical accidents when the storm hits. A little preparation can go a long way.

Avoid Using Electrical Equipment During Storm

When a cyclone is in full swing, it’s best to steer clear of all electrical equipment. Using devices during intense storms can put you at serious risk of electric shock, especially if your home is affected by flooding, lightning or power surges.

Here’s what to keep in mind:

• Stay off wired electronics – Avoid using corded phones, desktop computers, or anything plugged directly into a powerpoint.
• Don’t touch wet appliances – If water has entered your home, don’t risk using anything electrical until it’s been checked by a professional.
• Use battery-powered lights – Opt for torches or lanterns instead of mains-powered lighting.
• Avoid charging devices – Even plugging in phones or laptops during the storm can be risky.
• Wait until it’s safe – Only resume using equipment once the cyclone has passed and power has been safely restored.

Playing it safe now can prevent serious accidents later.

Avoid Fallen Powerlines and Damaged Wiring

After a cyclone, it’s not uncommon to see fallen powerlines or exposed wiring − and they’re far more dangerous than they look. Even if a powerline appears inactive, it could still be live and carrying a deadly current.

That’s why the golden rule is simple: never touch fallen powerlines or damaged electrical wiring.

Keep at least eight metres away from any downed cables, and make sure children and pets do the same. If a powerline is across your property or near your home, don’t try to move it yourself − call your local energy provider or emergency services immediately.

The same goes for any damaged or wet electrical wiring inside your home. Don’t attempt DIY fixes. Water and electricity are a hazardous mix, and one wrong move could result in serious injury.

Always wait until a licensed electrician confirms it’s safe before touching or using any damaged electrical fittings.

Inspect for Electrical Damage After the Storm

Once the cyclone has passed and it’s safe to go outside, it’s important to carefully inspect your home for any electrical damage before turning the power back on. Hidden hazards can pose serious risks if not handled correctly.

Here’s what to look out for:

• Check for exposed or frayed wiring – Don’t touch any damaged wires; take photos and call a licensed electrician.
• Look for water-damaged outlets or powerboards – If they’ve been wet, they may need replacing.
• Inspect appliances before use – If an appliance was exposed to water, don’t plug it in until it’s been professionally checked.
• Be alert for sparks or burning smells – These are clear warning signs of electrical faults.
• Don’t restore power yourself – If you turned off the mains, only turn it back on if you’re sure everything is safe – or get an expert to do it.

When in doubt, always call a professional. Safety first.

Use a Generator Safely If Needed

If a cyclone knocks out your power, a generator can be a lifesaver − but only if it’s used correctly. Generators produce electricity and fumes, so where and how you use them matters.

Always place your generator outdoors in a well-ventilated area, never inside your home, garage or near windows. The exhaust fumes contain carbon monoxide, which is invisible and deadly.

Make sure the generator is on a flat, dry surface and protected from rain. Wet conditions and electricity don’t mix, so keeping it covered (without enclosing it completely) is key.

Never plug a generator directly into your home’s power system unless you have a professionally installed transfer switch. This can cause “backfeeding”, which sends electricity back into the power grid − posing a serious risk to utility workers and neighbours.

A Little Preparation Goes a Long Way

Cyclones can cause chaos, but a little preparation goes a long way − especially when it comes to electrical safety.

By turning off the power at the main switch, unplugging appliances, keeping devices dry and avoiding fallen powerlines, you can help protect your home and your loved ones from serious electrical hazards.

It’s just as important to stay cautious after the storm has passed. Inspect your property carefully and never take chances with damaged wiring or wet appliances − always call a licensed electrician if you’re unsure.

Generators can help during blackouts, but they need to be used with care to avoid carbon monoxide poisoning or backfeed risks.

Ultimately, staying calm, planning ahead, and knowing what to do will help keep you safe during any storm. Because when it comes to electricity, safety should always be your top priority.
