Giải thích
Title 8 §1541.1 requires spoil, tools, and other materials to be kept at least 2 feet from the trench edge, or restrained by a retaining device. Material stacked at the lip adds surcharge load that can trigger a cave-in and can roll back onto workers below. The 2-foot setback also keeps loose material from falling in.
