Firefighters from the regional department were called when 800 cubic meters (1046 cubic yards) of cardboard, paper and wood scraps in an outdoor recycling space had caught fire, the spokesperson said.

Tesla's fire department took over command of the operation about five hours later, though local firefighters remain on the scene.

The cause of the fire has not yet been determined and police are looking into it, a regional spokesperson said.

Tesla was not immediately available for comment on the cause of the fire or whether it would have any impact on output.
