Lithium-ion batteries store a large amount of energy in a small amount of space. These powerful batteries can potentially overheat and pose a fire hazard when they are not used the right way. Like any product, a small number of these batteries are defective which can also cause them to catch fire.
Lithium-ion battery fires give off toxic gases and burn extremely hot, making them difficult to put out.
For small batteries: If you have a class ABC or BC fire extinguisher and are trained on using it, attempt to extinguish the fire. If you are not trained or do not have a fire extinguisher, get out of your home and call 9-1-1.
For large batteries: Because of the way the batteries are encased and the toxic nature of the gases, do not try to put them out. Leave the building or area and call 9-1-1.
Do not put lithium-ion batteries in the garbage and do not store discarded batteries in piles.
Batteries need to be separated and taken to a recycling retailer for safe handling. If they end up in any of The City of Tucson bins, the batteries can get crushed by equipment leading to fires at the recycling facility, or landfill sites.
