Lithium batteries store a lot of energy in a small space. If a battery overheats or becomes damaged, it can fail and ignite very quickly. While incidents are uncommon, fires involving rechargeable devices most often start while a battery is charging or if the device has been damaged or used with the wrong charger.

With this in mind, HHA has shared some simple advice that can help reduce the risk and help keep your home safe.

Charging devices safely

One of the most important things to remember is to avoid leaving devices charging unattended. If you use a rechargeable vape, do not leave it charging overnight or while you are out of the house. If something goes wrong during charging, it’s much safer if someone is around to notice.

It’s also important to use the correct charging equipment. Always use the charger that came with your device, as using incorrect chargers or cheap replacement cables can cause the battery to overheat. Charging on a flat, stable and non-flammable surface is also recommended, such as a table or worktop. Sofas, beds and carpets can trap heat and increase the risk of a problem developing.

Once a device is fully charged, unplug it rather than leaving it connected for long periods of time. It’s also best to avoid charging or storing devices in extreme temperatures. For example, leaving a vape on a car dashboard in direct sunlight can expose the battery to temperatures of 60–70°C, which may cause it to fail.

Using vape devices safely

Looking after the device itself is just as important. Only buy vape devices from reputable retailers and check they display UKCA or CE safety marks. Batteries should never be crushed, punctured or exposed to water, and loose batteries should not be carried in pockets or bags alongside metal objects such as keys or coins, as this can cause a short circuit.

If a device ever becomes unusually hot, begins leaking, or the battery appears swollen or damaged, it should be stopped from use immediately and disposed of safely. Devices should never be tampered with, modified or mixed with components from other products.

Disposing of vapes safely

Vapes and their batteries should never be put in household rubbish or recycling bins. Lithium batteries can ignite when crushed in waste trucks or sorting facilities.

Instead, used vapes should be returned to the retailer if they offer a take-back scheme, or taken to your local household waste recycling centre, where there are dedicated bins for small electrical items.

What to do in an emergency

It’s important to know what to do if a device or battery catches fire. If this happens, do not attempt to tackle the fire yourself. Leave the property immediately, get to a safe distance and call 999.

Rechargeable devices are now part of everyday life, and when used safely, there’s no reason for concern. Taking a few simple precautions when charging and using devices can make a big difference in helping to keep your home, your belongings and the people around you safe.
