Trench construction, safety: Caterpillar 3128 crawler mounted backhoe supports large pipe section/spool in trench in constructing underground pipe. The 8 ft deep trench is so deep that the two workers installing the pipe cannot be seen in this photo. The trench has no support against sidewall collapse. Trenches 5 feet (1.5 meters) deep or greater require a protective system unless the excavation is made entirely in stable rock, and this soil is not stable rock. Worker safety (and the law) also require that workers have easy, close exit from trenches, which pipes crossing the trench prevent. Michigan 2006
