In addition to cell phones and other hand-held devices, electric tools, cars, bikes and scooters have been growing in popularity over recent years. As the use of rechargeable lithium-ion batteries grows, so does the risk of fire – and protecting yourself and your family.
It’s important to remember that lithium-ion battery fires differ from other fires as they can burn hotter, don’t require oxygen, and can explode without warning. The primary cause is “thermal runaway” which occurs when a battery gets too hot and triggers a chain reaction that can lead to ignition.
The Mentor Fire Department has responded to several calls in recent months related to battery fires. Here are some tips to help you stay safe while recharging your devices.
HEED WARNING SIGNS
If your batteries are overheating, swelling, or producing unusual odors, smoke, or hissing sounds, immediately unplug your charger and carefully take your batteries outside to cool off before safely disposing of them.
KEEP IT COOL
Lithium-ion batteries can heat up while in use. Let your battery cool down before charging. Not only will it reduce the risk of overheating, it can also help extend the life of your battery.
KEEP AN EYE ON IT
Although it’s convenient to charge your device overnight while you sleep, it can also be dangerous. Always charge your batteries in a well-ventilated area away from flammable materials.
CHARGE SAFELY
Charge larger battery packs for tools as well as electric bikes and scooters outside when possible. These devices should never be charged near an exit and should be stored in a garage or shed when not in use.
FREE & CLEAR
Last but not least, always make sure that you can quickly and safely exit your home in the event of a fire. Make sure that entryways aren’t blocked – especially by a device that’s charging. Also, make sure the smoke alarms in your home are in good working. Precious seconds can mean the difference between life or death.
