Abstract: At 10:30 a.m. on November 25, 2020, Employee #1, employed by a demolition and concrete contractor, was working at the site of a one-story plus basement multifamily apartment building that was being demolished. The employee was collecting lumber and trash to throw into an approximately 12-foot deep excavation where the concrete foundation and basement walls had been removed, exposing bare earth walls. The employee was working from a concrete and metal stairway. The stairway's support legs had been undermined at the edge of the excavation when a concrete wall had been removed. The stairway collapsed into the excavation, and the employee fell, a fall height of 10 feet, and struck his head and back on concrete debris at the bottom of the excavation. Emergency services transported the employee to the hospital, where he was admitted and treated for multiple injuries including a traumatic head injury and a severed spine. Employee #1 died at the hospital on November 28, 2020.
