Explosion rocks Wisconsin refinery, injuring 11 and forcing evacuations
An explosion rocked a refinery in northwestern Wisconsin on Thursday, injuring at least 11 people, forcing the evacuation of homes, schools and a hospital, and sending a plume of noxious smoke billowing into the air.
Authorities said a tank of crude oil or asphalt exploded at the Husky Energy oil refinery in Superior, a city of about 27,000 that borders Minnesota and the westernmost tip of Lake Superior. That prompted them to order the evacuation of a 3-mile radius around the refinery, as well as a 10-mile corridor south of it where the smoke was heading.
It was unclear how many people were evacuated. The refinery is in an industrial area, but there’s a residential neighborhood within a mile to the northeast. The corridor downwind to the south of the refinery is sparsely populated.
There were no reported deaths, but at least 11 people were injured, including one who was seriously hurt. They were being treated at hospitals in Superior and nearby Duluth, Minn.
Fire officials said the explosion happened around 10 a.m. and the fire was extinguished by 11:20 a.m., though the plant was still smoking. Superior police later tweeted that the fire had reignited and urged residents living within the evacuation area to leave. Police blocked roads into the area around the refinery. Three schools and St. Mary’s Hospital in Superior were being evacuated as a precaution.
Essentia Health spokeswoman Maureen Talarico said one of the 10 patients at Essentia facilities had a serious blast injury; the other nine had injuries that were not life-threatening. St. Luke’s Hospital in Duluth was also treating one person, who was in fair condition, spokeswoman Jessica Stauber said.
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.
Kara Tudor, 30, and Julia Johnson, 27, live about 2 miles from the refinery and were ordered to evacuate. They quickly scooped up their two dogs and three cats, grabbed their toothbrushes and drove to a friend’s house in Duluth, where they were watching the news for updates.
Johnson was working from home at the time of the blast. She said the windows shook.
“It felt like something had hit the house, like a vehicle or a branch from a tree. … Our dogs started barking. It was a stressful moment,” she said.
