Which of the following is an option for protective shoring systems?

Proper shoring or benching is essential for maintaining safety during excavation work. This method involves the use of structural supports to hold up the sides of a trench or excavation site, preventing cave-ins which can pose serious risks to workers. The application of proper shoring systems ensures that the excavation walls are adequately supported, allowing for safe access and operation within the trench.

Using proper shoring or benching techniques is crucial in various circumstances, particularly in areas with unstable soil conditions or when working at significant depths. These practices are often guided by regulations and best practices to protect not only the workers on site but also the integrity of the surrounding environment.

Other choices, such as weekly inspections or excessive excavation, do not directly relate to the application of protective shoring systems. Weekly inspections are important for overall site safety but are not a type of shoring system. Similarly, excessive excavation does not provide any protective measures and can lead to more hazardous conditions. The mention of all types of piping does not pertain to protective shoring either, as it refers to materials used in construction rather than safety measures within excavation practices.
