This workplace hazard and ways to prevent fatalities are well known. Yet OSHA inspectors too frequently see excavation operations, like waterproofing foundations and installing septic and water management systems, without cave-in protections in place. Every excavation operation that is below ground at a depth of 5 feet or more requires protections from cave-ins. It is important that all employers and supervisors take a step back, evaluate the hazards, and take necessary steps to protect workers before allowing them to enter any excavation site.
