Trenching and Excavation Toolkit

Trenching Slope in Soil
Working in trenches and excavations can be one of the most dangerous construction operations. Soil cave-ins pose the greatest risk, but there are other potential hazards including fall into the trench, loads falling striking workers, hazardous atmospheres present, and being stuck by mobile equipment. The Occupational Safety and Health Administration's (OSHA) Excavation and Trenching Standard is designed to protect workers from these hazards.
