Each employee at the edge of what depth excavation must be protected from falling?

Protection from falling is mandated in OSHA regulations when employees are working at a certain depth of excavation. Specifically, at depths of 6 feet or more, safeguards must be implemented to prevent employees from falling into the excavation. This requirement stems from the increased risk of serious injury associated with falls from these depths, as they can result in significant impact injuries.

Therefore, the requirement to ensure protection at 6 feet emphasizes the need for safety measures such as trenches, guard rails, or other fall protection systems to safeguard workers in situations where they are exposed to potential falls from an edge. This standard helps ensure the well-being of employees, thereby reducing accidents and enhancing safety in excavation work environments.
