Tesla Faces Lawsuit Over Alleged Fire Hazards at Hayward Facility
2/28/2026, 5:34:44 AM
Allegations of Unsafe Working Conditions
Nina Mirani, a former regional manager at Tesla Energy, has filed a lawsuit claiming she was terminated for raising concerns about hazardous working conditions at the company's battery distribution warehouse in Hayward, California. According to court documents, Mirani described the facility as overcrowded and a "hub" that is "ripe for a potentially catastrophic fire." The complaint alleges that management regularly overstocked the warehouse with lithium-ion batteries, creating dangerous conditions for employees who navigated confined pathways while handling high-voltage materials.
Mirani's concerns were reportedly dismissed by her superiors, who continued to send large quantities of batteries to the facility despite her warnings. The lawsuit highlights the risks associated with lithium-ion batteries, which can ignite and burn at extremely high temperatures, making them difficult to extinguish. Mirani's allegations follow a pattern of battery fires at other Tesla facilities, including two incidents at a lab in Palo Alto and multiple fires at the Fremont vehicle manufacturing plant.
Management's Response and Termination
Mirani began her career at Tesla in January 2019 and was transferred to the energy storage division in 2023. She was responsible for overseeing the Hayward hub, which is a key intake location for Tesla's Powerwall products. Despite her repeated requests to reduce the battery inventory to mitigate fire risks, management allegedly ignored her pleas. In a PowerPoint presentation to a senior executive, Mirani outlined significant safety concerns, but her warnings went unheeded.
In February 2025, after escalating her concerns to higher management, Mirani was terminated. Tesla cited performance issues as the reason for her dismissal, claiming that several shipments had been lost under her supervision. However, the lawsuit contends that this justification was a pretext, as Mirani had received positive performance reviews and no missing shipments were ever documented.
Criticism and Legal Proceedings
The lawsuit also claims that two other employees who raised safety concerns were terminated on the same day as Mirani, while an employee who did not voice any safety issues was retained. Mirani is seeking damages for humiliation, mental anguish, and emotional distress resulting from her termination.
Tesla has responded to the lawsuit by filing a motion to dismiss, arguing that Mirani's employment agreement mandates arbitration for workplace claims and that her termination was justified based on legitimate reasons. The company also contends that any emotional distress experienced by Mirani was due to pre-existing conditions rather than actions taken by Tesla.
What's Next
An initial case management conference is scheduled for June 1, where further proceedings regarding the lawsuit will be discussed. The outcome of this case could have implications for Tesla's safety practices and employee treatment, particularly in light of the serious allegations raised by Mirani regarding fire hazards at the Hayward facility.
