What is the minimum distance a pile of excavated material should be from the edge of a trench?

The correct answer highlights the importance of maintaining a safe distance between excavated material and the edge of a trench to prevent potential hazards. Keeping the pile of excavated material at least 2 feet away from the trench edge helps mitigate the risk of the material sliding or collapsing into the trench. This distance is a safety measure intended to protect workers in the trench from being exposed to falling materials, which can cause injuries or fatalities. By adhering to this guideline, safety is ensured, along with the stability of the trench itself. This distance also allows for adequate space for equipment movement and access, further promoting a safer working environment.
