"Her skin was hanging off her hand, her right hand right here. Her hair was singed, it was all black burnt , eyebrows, eyelashes stuff like that. She was in shock, she was having trouble breathing," said Tony Green. He was in the area and tried to help. "She got blown out the door. We came over here to help her, to this other building on the side of it."
Firefighters were facing a difficult situation. The companies convert vehicles to run on natural gas, so there was danger everywhere.
"The whole building is one big explosion waiting to happen," said Detroit Fire Chief Gene Biondo. "There's compressed gas everywhere in the building."
The cause of the explosion is still under investigation, but it appears propane was to blame.
"They were repairing a propane tank on a vehicle," said Senior Fire Investigator Terrence Lane. "We suspect that the low-lying propane fuel probably went to a fuel source and flashed back and caused a fire,"
