Thousands of gallons of nitric acid, a hazardous chemical compound that can irritate eyes, throats and lungs, leaked from a tank at the Austin Powder Red Diamond plant in McArthur on Wednesday morning. The company produces industrial explosives used for construction and mining purposes. It is unclear how the leak started - but thick orange plumes of smoke were seen billowing across the blue sky in the area. An immediate evacuation order has been announced by the Vinton County Sheriff's Office, specifically for Zaleski - a small village in Ohio with a population of 750 locals.
