An excavation is any man-made cut, cavity or depression in the earth’s surface, formed by earth removal. This includes a trench, which is a narrow type of excavation made below the ground that is deeper than it is wide. Trenches can be up to 15 feet wide. Trenches and excavations are common at many construction sites and are considered one of the most dangerous construction operations. It is estimated that 100 plus deaths per year occur due to cave-ins and other excavation hazards. OSHA requires that workers in trenches and excavation areas be protected. Most fatalities and injuries could be avoided with proper knowledge, utilization of OSHA safety standards and an effective health and safety program.
There are many hazards associated with excavation and trench work. 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 do not have to be deep for accidents to occur. Serious injuries are possible in shallow trenches (under 5 feet) as well.
