The civilian contractor who was seriously injured Monday at the Boone National Guard Center in Frankfort is Wade Massingale.
A snorkel boom lift collapsed and fell about 11:45 a.m., killing another civilian contractor and injuring Massingale.
The Associated Press reported that Brandon Cloud, 23, of Harlan County died at the site.
Massingale was taken to University of Kentucky Chandler Hospital, National Guard spokesman David Altom said. He was listed in serious but stable condition, Altom said.
Cloud and Massingale were using the lift to install siding on an aircraft hangar at the center. They worked for Davis Brothers Roofing, Altom said.
The Kentucky Labor Cabinet will be part of the accident investigation, Altom said.
