Duluth, MN (Northland's NewsCenter) - 41–year–old Joe Fredrickson was rushed to the Miller Dwan Burn Center in Duluth Monday, after two explosions rocked the seventh floor of the Taconite Harbor Energy Center Plant, in Schroeder.

Fredrickson has worked there as a fuels technician since 2001.

Officials say they're still unsure as to what sparked the explosions, but fire crews say signs point to highly flammable coal dust somehow igniting.

Fredrickson is being treated at Essentia Health Duluth.

The plant is owned by Minnesota Power.
