What minimum distance should the closest contact point be from a recently backfilled trench?

Explanation:
Recently backfilled trenches can be unstable because the soil hasn’t fully settled yet. To keep a safe margin for any movement of the fill or a possible partial collapse, the closest contact point should be kept at a distance equal to the depth of the trench. This one-depth clearance provides a practical buffer against settling, vibrations, or shifting of the backfill, reducing the risk of the crane or its load contacting the trench and triggering a problem. If the trench is deeper, the required buffer scales accordingly, and while a larger distance would be safer, the minimum is to match the trench depth.
