When is it necessary for the competent person to inspect shoring systems?

The necessity for a competent person to inspect shoring systems after any structural changes or damage is crucial for maintaining safety on excavation sites. Structural changes may arise from various factors such as the installation of additional supports, alterations to nearby structures, or environmental conditions like heavy rain which could affect soil stability. Damage could result from equipment impact, ground movement, or evolving site conditions.

Regular inspections ensure that the shoring systems remain effective in providing the necessary support to prevent collapses, which can pose significant risks to workers. These inspections help identify potential hazards early, allowing for timely interventions to reinforce or adjust the shoring as needed, thus ensuring the safety and integrity of the excavation site.

While other options mention periodic inspections or requests from workers, these do not fully encompass the critical need to respond dynamically to changes that can affect the structure's integrity.
