Tesla confirmed a Thursday night fire contained to a cardboard bailing machine at its Fremont, California, factory, where the Model 3 electric sedan is being built. It is the latest in a series of fires to break out at the facility.

"Last night, the structure outside our factory that houses the cardboard and other wood and paper products that are being recycled caught fire," a spokesperson from Tesla said. "There were no injuries and we'd like to thank the Fremont Fire department for putting it out quickly. We're investigating the cause."
