Abstract: At 12:24 p.m. on September 25, 2017, Employee #1 and Coworker #1, employed by a construction company, were preparing to install framing trusses at a residential construction project. They were standing on opposite top plates and facing a bundle of 10 trusses that was sitting across the top plates. As they cut the straps holding the bundle together, the trusses began to fall. One truss struck Employee #1's leg, and he fell from the top plate, a fall height of 12 feet. Emergency services were called, and Employee #1 was transported to the hospital. He was admitted and treated for a fractured left ankle that required surgery.
