A competent person must conduct documented inspections of each excavation for what condition?

The correct answer emphasizes the necessity for a competent person to conduct documented inspections of each excavation before each work site and throughout the work shift. This requirement is rooted in safety regulations designed to minimize the risk of accidents and ensure the integrity of excavation work.

Regular inspections are essential because conditions can change rapidly due to environmental factors, equipment use, or other activities happening nearby. By ensuring that inspections are documented and occur both before commencing work and periodically throughout the shift, any potential hazards can be identified and mitigated in a timely manner. This ongoing oversight is critical in maintaining not just compliance with safety regulations, but also the health and safety of workers on the site, as it allows for immediate responses to new conditions that may arise during excavation activities.

Documented inspections provide a formal record that can be referenced later should safety issues arise, fostering accountability and reinforcing safety protocols. This proactive approach supports both the completion of the project in a safe manner and compliance with the standards set by USACE EM 385-1-1.
