General Motors’ Factory Zero, a significant hub for the automotive giant’s electric vehicle production, experienced a significant disruption on Tuesday due to a fire outbreak within the facility. Detroit Fire Chief James Harris confirmed that a third-alarm fire was called late Tuesday afternoon, necessitating considerable manpower to combat the blaze.

The fire, originating from lithium-ion batteries, caused heavy smoke to permeate the expansive 4.5 million square foot plant. Harris noted that there were no injuries among firefighters, civilians, or GM employees. However, a precautionary evacuation was conducted, and as of Tuesday evening, the situation was still being actively managed to prevent any injuries.

GM spokeswoman Tara Kuhnen informed that all employees were safe and accounted for. The company is actively investigating the incident. The immediate response led to the cancellation of the second shift for the night.

Factory Zero is not just another production facility for GM; it’s a cornerstone in their transition to electric vehicle manufacturing. The plant employs approximately 1,880 people and is responsible for producing key models like the GMC Hummer all-electric pickup and SUV, along with the Chevrolet Silverado EV work truck.

This fire incident marks the second such occurrence at Factory Zero in recent months. An earlier incident on October 25, revealed through a Freedom of Information Act request, involved a fire that was extinguished with the help of the facility’s water sprinklers. This incident highlighted issues with the ventilation system.

Kuhnen reassured that their investigation into the October incident confirmed the proper operation of all safety systems and that the cause was a non-battery-related component, which has been rectified.
