- The fire was contained to a cardboard bailing machine and there were no injuries, according to Tesla.
- Thursday night's incident is the latest in a series of fires at the facility.
There was another fire at Tesla on Thursday night, the company confirmed. The fire affected a cardboard bailing machine at its Fremont, California factory and was put out quickly. It's the latest in a series of fires to break out at the company's factory where the Model 3 is being built.
"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."
The fire was unrelated to the new GA4 production line and did not affect output, according to Tesla.
Musk warned employees to look out for foul play, asking them to "be on the alert for anything that's not in the best interests of our company."
Before Sunday's fire, employees reported that there had been at least four fires at the facility's paint shop since 2014. One in April was so severe that it stopped production for multiple shifts over the week.
