Refinery a few miles from downtown Salt Lake City, according to refinery operations manager John Progress. Progress said the man emptied surplus gas from fuel hoses into a steel bucket, which apparently built up static electricity and burst into flames.  The man threw the bucket away from his body, and it sparked an explosion. Refinery offices were evacuated and the underground pipes moving petroleum products were shut off. Firefighters took nearly an hour to douse the flames, and the thick black smoke was easily visible from miles away.  Nearby fuel storage tanks were blistered by the heat, but none exploded. Refinery president Phil Adams said the fire was limited to the loading area and wasn't expected to disrupt operations.  The refinery made plans to have gas loaded elsewhere starting Saturday as cleanup and an investigation continued. Adams said this fire was less serious than some previous accidents at the refinery, including a 1994 incident in which one worker died. "When you're dealing with flammable products, there's always a potential for an accident," Adams said.  "What's really important is that nobody got hurt."   Sources ( * indicates the original source) Source Details   Media - Associated Press * 03-18-2000 0048EST
