Abstract: At approximately 2:30 on July 12, 2007, Employee #1 and coworkers were installing 8 in. diameter PVC sewer pipe in an approximately 8 ft deep trench. A coworker had just left the trench to get a connector when the entire east side caved in and buried Employee #1. He was killed. The Morton County Sheriff, EMS, and Fire Rescue responded to the rescue attempt, but Employee #1 was pronounced dead at the scene. The trench had been neither sloped nor shored to prevent a trench wall cave-in.
