A fire broke out at Foxconn's main iPhone manufacturing facility in Zhengzhou, China on Sunday, according to a report from The Wall Street Journal.
There were no reported casualties and a Foxconn spokesperson told the Journal that the fire will not impact production. At this point, it's still unclear what caused the blaze, which started in the central air conditioning fan and ventilation ducts on the roof of one of Foxconn's Zhengzhou plants and spread to several floors within the factory. Local authorities are investigating the incident.
Foxconn did not immediately respond to a request for comment.
Unfortunately, this is not the first such incident for Foxconn in recent years. In 2011, a fire broke out at a different Foxconn plant in China where Sony laptops, computer components, and printers were being assembled. That fire was sparked by electrical cables on the roof.
That same year, the company briefly shut down operations following a deadly explosion in Chengdu, prompting Foxconn and its partners to promise a number of reforms at the manufacturer's facilities.
Foxconn has come under fire in recent years for other problems as well, including worker suicides and alleged slave-like working conditions. At least two dozen Foxconn workers in Shenzen and Chengdu have taken their own lives since early 2010. Foxconn has forced employees to sign a pledge promising that they won't commit suicide and installed nets outside factory dormitories to deter potential jumpers.
As of 2014, Foxconn had more than 200,000 employees dedicated to making iPhone handsets and their key components at its Zhengzhou, China-based factory.
