One of the biggest fire hazards in your home could be connected to your wall right now.

Firefighters across the country are commemorating Fire Prevention Week by highlighting the dangers of overcharging batteries and electronic devices and encouraging people to make safe charging a superpower. Lithium-ion batteries are responsible for an increasing number of destructive house fires across the country. Fires involving the batteries are especially dangerous because of their scorching temperatures, toxic smoke and risk of reignition.

In August, an overcharged lithium-ion battery was blamed for a $60,000 apartment fire in Kaukauna. Southern Door Fire Department Chief Rich Olson has also seen the damage caused by lithium-ion battery fires after responding to one that destroyed a building in his jurisdiction.

He says there are some simple steps you can take to prevent fires when charging batteries and devices, such as charging them on a hard surface, disconnecting the charger when you are done and avoiding aftermarket chargers.

To celebrate Fire Prevention Week, the Southern Door Fire Department will host an open house at its Forestville station from 10 a.m. to 1 p.m. Saturday. The event will feature a firehouse bounce house, exit truck maze, fire truck tours and more.
