What is the minimum clearance for materials near an excavation edge to prevent hazards?

The minimum clearance for materials near an excavation edge is set at 2 feet to ensure safety and reduce the risk of potential hazards such as materials falling into the excavation or causing a collapse. This distance is established in safety regulations to maintain a safe working environment around excavation sites, where the stability of the ground can be compromised. Keeping materials at least 2 feet away helps to prevent not only accidental shifting and sliding of materials but also protects workers from injuries that might arise from falling objects. Maintaining this clearance is critical for ensuring the stability of the excavation site and the safety of personnel working nearby.
