(Vancouver, WA) -- No injuries are reported after the battery on an electric scooter caught fire Monday in Vancouver, Washington. Hazardous Materials firefighters say the battery experienced a thermal runaway which caused the fire and allowed toxic gases to be released. Firefighters wore protective suits and breathing masks while they put the scooter in a salt-brine filled container to cool the thermal runaway and drain the power in the battery cells. Firefighters say batteries that are damaged, have swelling, leaking or get hot should be disposed of at a recycler.
