What capacity must a protective system have according to safety standards?

The capacity to resist all loads applied or expected is crucial for a protective system in excavation work because it ensures the safety and stability of the structure in various conditions. Protective systems, such as trench boxes or shoring, are designed to prevent collapses and protect workers from potential hazards during excavation activities. If the protective system cannot withstand the loads that may be imposed on it – including the weight of soil, equipment, and any additional live loads from working personnel – it could fail, leading to serious accidents or injuries.

Adhering to this standard is vital as it encompasses not just the expected conditions during normal operations, but also unforeseen events that may increase load on the protective system. By ensuring that the protective system has sufficient capacity against all anticipated and unexpected loads, operators and supervisors can maintain a safe working environment and comply with safety regulations designed to prevent trench collapses and related hazards.
