Giải thích
Under Title 8 §1541(c), trenches 4 feet or deeper must have a stairway, ladder, ramp, or other safe means of egress located so no worker travels more than 25 feet laterally to reach it. A ladder must extend at least 3 feet above the trench edge. Quick egress is critical because cave-ins happen in seconds.
