Matthew Kent with the Douglas County Fire Department says crews were called shortly before 5 p.m. Wednesday. Kent says there was a hydrogen sulfide leak at Young Refining in Douglasville.
Kent says one man died after falling from a height of 20 feet after his mental state was altered by gas inhalation. His name was not immediately released.
Kent says three other people were injured. One suffered gas inhalation, one suffered cardiac arrest and the third had a minor injury.
A man who answered the phone at a number listed for Young Refining said the company had changed its name to ARTC and declined to comment.
