Abstract: At approximately 6:40 p.m. on April 29, 2009, Employee #1, a construction laborer, and two coworkers were digging a trench in order to connect a sewer line to the sewer main. The excavation was measured to be 66 feet long and 70 inches across. The depth varied, with the maximum depth measured at 8.08 feet. The walls of the trench were not sloped and no shoring was used. The soil of the excavation was classified to be Type B. The trench collapsed and partially buried the three employees. Employee #1 was buried to his waist and suffered a fracture to his ankle. The three employees were rescued by the fire department, and Employee #1 was taken to the hospital, where he was admitted for treatment.
