Abstract: At 9:00 a.m. on April 13, 2017, Employees #1 and #2, employed by a painting contractor, were engaged in exterior painting at a multifamily residential building site. They were moving an aerial lift to position it on the building's north side. As they moved the lift up an incline, they drove over a covered septic tank. The lift broke the septic tank's concrete cover, and a wheel of the lift plunged down. Employee #1 was catapulted out of the lift and fell 80 feet. Employee #2 was slammed into the lift's guardrails. Emergency services were called, and the workers were transported to the hospital. Employee #1 was admitted and treated for multiple facial fractures, a fractured hip, and fractured shoulders. Employee #2 was admitted and treated for neck trauma and a fractured arm.
