OSHA 500 Trainer Course in Occupational Safety and Health Standards for the Construction Industry – Practice Test Prep & Study Guide

The description of a benching system as a series of horizontal levels or steps with vertical surfaces is accurate as it aligns with the guidelines set forth by OSHA regarding excavation safety. A benching system is specifically designed for excavations where the walls are shaped in a stepped fashion to help prevent collapse. This method allows for safe access and egress to the excavation by providing safe, level surfaces to work on at different elevations.

The design of a benching system is particularly useful in various soil types, ensuring that the structure is stable and reducing the risk of cave-ins, which is a significant hazard in excavation work. The horizontal levels not only provide a means to work safely but also help in managing the weight distribution of soil above the excavation, which is crucial for maintaining stability.

Understanding the mechanics of benching systems is essential for any construction professional to ensure compliance with OSHA standards and to prioritize safety in excavation projects.
