German police say an explosion at an automotive supplier plant in Bavaria on Monday morning has left 13 people injured, according to a report by the Associated Press. Four of those injured suffered "serious wounds" and had to be airlifted to hospital via helicopter.
Authorities say there does not appear to be any danger for nearby residents, according to the AP.
The FAG Schaeffler factory, which is located in the town of Eltmann, mainly produces rolling bearing components. According to Jalopnik, they are the official technology partner of Audi's FIA Formula E Championship team, as well as a supplier for the Elio P4 trike.
A quick review of the company's website reveals they produce a wide variety of automotive parts beyond ball bearings such as valvetrain components, chain and belt drives, and transmission parts, in addition to myriad industrial products used in aerospace, railways, printing machines, power tools, bikes of both the motor and pedal variety, medical systems, and food processing machinery, among others. So, if it's made of metal and it moves, there's a decent chance there's a Schaeffler component in there somewhere.
The cause of this morning's explosion is unknown at this time. The factory in question is situated approximately 55 miles north of Nuremburg, in an industrial area of Eltmann.
