A five alarm fire broke out in northwest Dekalb County Thursday night, calling fire crews from 16 different companies.
Some straw in the building made it difficult to extinguish all the fire. Firefighters believe some type of tank exploded in a machine shed. The explosion appears to be accidental.
Investigators believe a piece of equipment malfunctioned and started the blaze. The fire spread to several building, but did not jump to the farmer's house.
One man tried to move some equipment out of the way and suffered some burns. He was taken to the hospital.
