Lithium-ion battery fire safety – Fire Line

In the past year, the Seattle Fire Department responded to 57 lithium-ion battery related fires. Lithium-ion rechargeable batteries are commonly used in home electronics such as phones, laptop computers, tablets, e-scooters and other devices that require plug in charging. These batteries are small and powerful but when used incorrectly, they can overheat, catch fire, or explode.

Lithium-ion battery fires are especially dangerous because of how quickly they can start and spread. They also produce harmful toxic gases.

How to be safe: 

• Only use chargers and cables that are compatible with and came with the device – an incompatible charger can cause the device to overheat 
• Do not charge a device while sleeping 
• Do not charge a device under pillows or bedding or on top of beds and sofas 
• Do not continue to charge the battery once it is fully charged  
• Do not charge near your primary exit  – if a fire starts, you will need a clear way out
• Keep batteries at room temperature and away from heat or direct sunlight 
• Stop using your device if the battery shows signs of damage, such as an unusual odor or change in color.   
• Purchase batteries and devices that have been certified by UL or another independent safety testing agency 

How to respond:

• Lithium-ion battery fires can start and spread quickly. They produce toxic gases and it’s safest to get away. Do not try to extinguish on your own.
• If your device begins to hiss and start a fire, immediately leave the area, close the door as you exit and call 911.
