LAKELAND, Tenn. -- A worker was seriously hurt after a propane tank exploded right in his face.
"I heard this huge explosion. It sounded like a transformer exploding," said Angela Flippen.
According to the Shelby County Fire Department a worker for the pipe lining company that contracts with the city of Lakeland was using a propane tank as he worked on a sewer line in the 4300 block of Mt. Gillespie.
The tank was used to heat hot water used while he worked.
Suddenly, the valve exploded in his face.
"It was really, really loud. Like it rang my ear. I was in my backyard and it disrupted my morning."
All morning, investigators could be seen photographing the area and talking to workers.
The victim was rushed to the Regional Medical Center in critical condition with second degree burns to his face.
"Oh my God. I feel really bad that I didn`t come running out here to help him. I didn`t know what it was."
Officials are still trying to figure out what caused the propane valve to go off.
