The deaths and injuries on March 21, 2011 likely resulted when water leaked into the electric arc furnace causing an over-pressure event, ejecting furnace contents heated to approximately 3800 degrees Fahrenheit. Along with molten calcium carbide, the furnace spewed powdered debris and hot gases, which blew through the double-pane reinforced glass window of the furnace control room that was located just 12 feet from open vents atop the furnace. The two workers inside died within 24 hours from severe burn injuries.
