Four New Castle County firefighters were injured in a floor collapse at a three-alarm townhouse fire in Wilmington Thursday.
Crews called a 'Mayday' after the floor they fell through a collapsed floor, NBC reported.
Three were taken to a hospital, and one suffered serious burns and smoke inhalation.
Paramedic Sgt. Abigail Haas told the media two of the firefighters were stable while a third is in serious but stable condition.
"I think it speaks volumes that there were no civilian injuries so that's great," Haas said. "Everybody got out and didn't try to go back into their home, which is a good thing."
Neighbors helped alert residents to the fire.
Weather conditions helped crews as well.
“That was very important,” Mill Creek Fire Company Deputy Chief Joseph Stewart said. “No wind was a good factor in keeping the fire contained."
It took firefighters about an hour to get the fire under control.
