Abstract: At 1:00 p.m. on April 11, 2018, Employee #1, a rigger employed by a construction framing company, was working at a multiemployer construction project, a seven-story multifamily residential building. He was on the fifth floor and unloading a bundle of two by four lumber. As he turned away from the load, he walked over a floor shaft hole that measured approximately 3 feet by 4 feet and that was not securely covered or labeled. The hole cover slipped, and Employee #1 fell through the hole to the concrete surface five stories below, a fall height of 50 to 60 feet. Emergency services were called, and Employee #1 was transported to the hospital. He was admitted and treated for massive head trauma and skull fractures. At the time of this report, Employee #1 was in a quadriplegic state and awaiting further surgeries to close skull fractures.
