Digging a narrow, deep cut in the ground to install underground pipes, cables, or utilities.
The excavation of a narrow, deep cut in the earth to install pipes, conduit, cables, or other underground utilities. OSHA classifies soil for trench protection requirements and mandates protective systems (sloping, shoring, or shields) for trenches over 5 feet deep. Trench safety is critical — cave-ins are among the most deadly construction hazards.
The 8-foot-deep sewer trench required aluminum hydraulic shoring per OSHA regulations before workers could enter.
