Tanker truck explodes in southern Wisconsin

LIMA TOWNSHIP, Wis. (AP) - Crews have a small fire under control after a propane tanker exploded at a farm cooperative in southern Wisconsin.

Rock County 911 supervisor Brian Becker says the explosion occurred Friday at a Cooperative Plus facility near the city of Whitewater.

Sheriff's Capt. Jude Maurer says 13 fire agencies responded and had the blaze under control within an hour.

Maurer says the blast tore holes in the sides of a metal building where a worker was transferring propane from a storage tank to a delivery tanker. The worker was able to run out of the building before the explosion. No one was hurt.

The Department of Labor issued $721,000 in penalties to Cooperative Plus after a worker was seriously injured at its Burlington facility in February 2010. They faced other penalties later that year for federal workplace safety violations at both its Whitewater and Genoa City sites.
