Lithium-Ion Batteries Safety Information
The Office of Children and Family Services (OCFS) has shared information related to lithium-ion batteries. These batteries are used to power electronic devices like smart phones, tablets, laptops, e-bikes, e-scooters, toys, electric vehicles, and even some smoke alarms. Because these batteries have become so commonplace in households and businesses, it’s vital you know how to use them correctly and how to respond in the event of an emergency.
When used incorrectly or if the battery is damaged or defective, lithium-ion powered devices can overheat and catch fire and may even explode. This information is not meant to deter use, but to make you aware of the risks.
Warning signs to look for:
Device is hot. While it is normal for batteries to generate some heat when they are charging or in use, if your device’s battery feels hot to touch, it may be defective and a risk of starting a fire.
Device is swelling or bulging, or the device has a lump or is leaking.
Device is making a hissing, cracking, or popping sound.
Device has a strong or unusual odor. Lithium-ion batteries emit toxic fumes when they fail.
Device is smoking.
If you notice any of these warning signs:
Stop using the device and turn it off immediately.
Unplug it from the power source.
If safe to do so, move the device to a safe, isolated area away from anything flammable using tongs or gloves to avoid touching the device or battery with your bare hands.
In the event of a fire, follow your Emergency Plan and evacuate the area, and Call 9-1-1.
