Brits warned of six dangerous and common fan mistakes as summer finally returns with sizzling temperatures next week

WARM summer weather is finally here with and temperatures could rise to 30C as early as next week.

Naturally, people will be digging out their fans to keep cool in the heat – but experts have warned about several common dangers to be mindful of.

In extreme cases, it could even result in a devastating fire.

Here are six common mistakes identified by safety charity .

1. Don’t leave your fan on overnight

A fan overnight might help you keep cool but it’s risky business.

Electrical Safety First’s expert Giuseppe Capanna warns you won’t have any idea if there’s an electrical fault while you sleep, which could lead to a fire.

Of course, most modern electric fans are safe to leave on for hours at a time and pose little to no threat.

Some also have timers – so you should consider using that to at least limit your fan from working away all through the night.

If you do choose to leave it on overnight, make sure the device is clear of dust and is far away from curtains.

Though there are no heatwaves yet, those who are at risk of severe heat stroke or other adverse health effects should leave their fan on.

2. Don’t buy second hand fans

It’s tempting to buy a second hand fan from sites like Facebook Marketplace to save a bit of cash.

But experts say it’s best not to.

That’s because it won’t have the same safety testing as it would from a reputable retailer.

Substandard imitations and old kit could risk electric shock and fire.

3. Keep your fan on a flat surface

It may sound obvious but it’s worth remembering that your fan should always be kept on a flat surface.

If it’s balanced precariously on the edge of a dresser or bedside table it could very easily fall off.

This risks the blades hitting the guard and putting the motor under additional strain – and ultimately cause overheating and even a fire.

Not to mention it risks breaking your fan too.

4. Clean the dust off

Over the years, your fan’s vents and motor can become quite clogged up with dust buildup.

This is especially the case if you’ve just dug it out from a closet for the heatwave.

Dust puts the motor under extra strain, increasing the risk of overheat and catch fire.

The dust itself can also act as a source of ignition if the motor were to overheat.

So make sure you regularly give it a clean.

Before cleaning the fan blades or motor, unplug the device and follow the manufacturer’s instructions in the manual.

5. Don’t use fans making electrical buzzing sounds

If your fan is giving off a faint buzzing sound it may be a sign of an electrical fault or ‘arcing’ occurring at the plug.

Always ensure your fan is plugged in securely and if you notice any smell of burning or unusual noises, turn it off immediately.

6. Check your fan for wear and tear

We often keep hold of fans for years, packing them away in the cooler months, where damage may occur to cables.

It’s important to check that the cables and vents are in good condition.

Damage to those parts can hinder the product’s performance.
