On April 26, 2018, an explosion and subsequent fire occurred at the Husky Energy Oil Refinery in Superior, Wisconsin. An initial explosion was reported at 10:00 AM and was extinguished close to noon, however a piece of debris had hit a storage tank containing asphalt, which ignited after spilling across the refinery, sending a thick plume of black smoke into the air. Thirty-six people, including 11 refinery employees, were sent to local hospitals, but there were ultimately no fatalities. Residents 3 miles to the east and west of the refinery, 2 miles to the north, and 10 miles to the south were evacuated from their homes temporarily due to concerns of both the toxicity of the smoke affecting those who lived south of the refinery and concerns regarding the plant's hydrofluoric acid tank causing further damage.[1][2]
