Fire departments nationwide are grappling with many critical issues, including the challenge of lithium-ion battery fires. As effective as these batteries are, they can sometimes “generate heat, produce flammable and toxic gases, and create explosions,” according to Andy Little of the Tulsa Fire Department. These incidents can happen due to exposure to extreme heat, physical battery damage, overcharging, or incompatible charging equipment.
In May, the department responded to a house fire caused by a dog chewing on a phone charger with a lithium-ion battery. While all the pets escaped safely through the dog door, the situation could’ve been much different if there were no means of escape or if the family was asleep.
These situations are why the National Fire Protection Association (NFPA) has tips on using lithium-ion batteries safely. They recommend:
- Following each manufacturer’s instructions
- Putting batteries in the device the right way
- Using batteries and cords designed for each device
- Keeping batteries at room temperature when possible
- Storing batteries away from anything that can catch fire
- Purchasing devices that are listed by qualified testing laboratories
- Disposing of batteries at designated recycling centers or household hazardous waste collection points.
There are also certain things to remember when leaving devices to charge. The NFPA warns against leaving devices on couches, under pillows, or on beds. They also say to not keep charging the device after it’s fully charged.
If a fire occurs even after taking these precautions, Brooks says to “immediately evacuate the building and call the fire department.” Lithium-ion battery fires are unique and very challenging to extinguish. However, closing the door to the charging area can help keep the fire contained until firefighters arrive.
There are answers to frequently asked questions about lithium-ion batteries on the NFPA website.
