Abstract: At 9:00 a.m. on May 16, 2017, Employee #1, employed by a construction company, was working at a multifamily residential building. He climbed up a ladder and onto the roof while carrying his 50-foot lifeline and an anchorage bracket. His intention was to install his fall protection system at the peak of the roof, which had a 9 to 12 pitch. Employee #1 had walked approximately 15 feet toward the roof's peak when he slipped on loose shingles and fell, a fall height of approximately 22 feet. He first hit a tree and then continued to fall and struck the ground. Emergency services were called, and Employee #1 was transported to the hospital. He was admitted and treated for an upper leg fracture of the femur.
