The fatal explosion, involving calcium carbide, occurred Monday evening at the Carbide Industries plant in Louisville's Rubber town district, a heavily industrial area with 10 other chemical plants near the Ohio River, authorities said. Firefighters were letting a chemical plant fire burn itself out following the explosion. A second explosion, which fire officials said involved mineral oil, rocked the site nearly five hours later but no one was reported injured.
