Explosion at refinery injures 11
At least 11 people have been injured and homes evacuated after a tank containing crude oil or asphalt exploded at a large refinery in Wisconsin.
No deaths have been reported but at least 11 people were being treated at hospitals in Superior, where the blast happened, and nearby Duluth, Minnesota.
The explosion at the Husky Energy oil refinery happened at about 10am yesterday, Superior Fire Chief Steve Panger said.
He said the fire was out by 11.20am, although smoke could still be seen rising from the plant.
Superior police later tweeted that the fire had reignited and urged residents living within a one-mile radius of the refinery to leave.
Police blocked roads around the refinery in Superior, which is home to about 27,000 people and borders Minnesota to the north and the tip of Lake Superior.
Mr Panger said a small tank containing either crude oil or asphalt exploded in the refinery.
A contractor who was inside the building told WDIO television that the explosion sounded like “a sonic boom” and that it happened when crews were working on shutting the plant down for repairs.
