The U.S. Chemical Safety Board (CSB) has dispatched a four-person investigative team from to the scene of yesterday’s explosions and fire at a Husky Energy oil refinery in Superior, Wisconsin. Eleven people were initially reported injured in the blast, which occurred as workers were shutting the refinery down in preparation for a five-week turnaround. The number of injured was later adjusted to six, with one person in serious condition. There were no reports of fatalities, and all workers at the facility were accounted for.
A mandatory evacuation order was issued for Superior residents living within a three mile radius of the refinery and ten miles south of it due to the heavy smoke. More than 30,000 people were affected.
