What is the function of a shield system?

The function of a shield system is to withstand forces from a cave-in and protect workers. Shield systems, often referred to as trench boxes or protective systems, are utilized in excavation sites to prevent soil collapse. When workers are operating in an excavated area, particularly in trenches, the risk of trench collapses increases, which can lead to serious injuries or fatalities. The shield system provides a stable and secure environment that effectively absorbs and redistributes pressures exerted by the surrounding soil, thereby safeguarding the workers inside the trench from potential hazards associated with cave-ins. This is critical for maintaining safety standards on construction sites where excavation is taking place. Other options do not accurately capture the primary purpose of a shield system, focusing instead on aspects unrelated to worker safety.
