Investigation Summary
At approximately 3:30 p.m. on February 11, 1986, Employee #1 came out of a 42 in. diameter concrete sewer line into a 6 ft 5 in. wide by 8 ft high by 20 ft long trench box that was being skidded under an existing 6 in. water line crossing the trench. The trench was 7 ft wide by 17 ft deep. An additional 4 ft high section had already been removed from the top of the trench box to allow it to pass under the water line. This exposed 9 ft of unshored wall above the 8 ft high bottom trench box section. The approximately 45 ft long south wall of the trench caved in, burying Employee #1. He was killed.
