According to firefighters, the construction crew was putting up roof trusses. They toppled leading to a domino effect that brought down about one-third of them. Most of the workers were able to safely get out of the way but seven workers were injured, including two who fell 20 feet.
The injured were taken to Lancaster General Hospital.
