2018 Husky Energy Refinery Explosion
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. Background The oil refinery in Superior, Wisconsin, which processes 50,000 barrels of oil a day, was acquired by Husky Energy from Calumet Specialty Products Partners in ...

(An office building built on part of Central's site was completed in 2008 and a housing project was built on East's site, the last lot being developed in 2012). The high school serves about 1,600 students in grades 9–12 with a staff of around 150.

Hydrogen Fluoride
Hydrogen fluoride (fluorane) is an inorganic compound with the chemical formula . This colorless gas or liquid is the principal industrial source of fluorine, often as an aqueous solution called hydrofluoric acid. It is an important feedstock in the preparation of many important compounds including pharmaceuticals and polymers, e.g. polytetrafluoroethylene (PTFE). HF is widely used in the petrochemical industry as a component of superacids. Hydrogen fluoride boils at near room temperature, much higher than other hydrogen halides. Hydrogen fluoride is an extremely dangerous gas, forming corrosive and penetrating hydrofluoric acid upon contact with moisture. The gas can also cause blindness by rapid destruction of the corneas. History In 1771 Carl Wilhelm Scheele prepared the aqueous solution, hydrofluoric acid in large quantities, although hydrofluoric acid had been known in the glass industry before then. French chemist Edmond Frémy (1814–1894) is credited with discoveri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...
