All excavations are hazardous because they are inherently unstable. Workers can be seriously injured or killed if the sides of a trench collapse. Unsafe trenches are the major factor in many trenching hazards. Trenches don’t have to be deep for accidents to occur. Serious injuries are possible in shallow trenches (under 5 feet) also. A cubic yard of dirt can weigh up to 2700 pounds and is capable of moving at 25 feet per second. A cave-in makes very little noise, and gives very little warning prior to the collapse. Digging can be a major cause of concern unless you know proper techniques and the OSHA rules for excavation and trenching.
