Three construction workers are recovering from injuries after the roof of the building they were working on collapsed in western Pennsylvania.
Fire officials say the workers had to be pulled from the debris after roof trusses collapsed Wednesday during the construction of a sports and entertainment complex in Adams Township, Butler County.
Adams Area Fire Chief Albert Minjock says the workers complained of pain in their chests and extremities after being rescued. All three were conscious and flown to Pittsburgh hospitals.
Minjock said the construction site looked like a pile of matchsticks after the 60-foot trusses tumbled down in succession.
The Occupational Safety and Health Administration is investigating.
