Giải thích
Title 8 §1541 requires the competent person to inspect excavations, adjacent areas, and protective systems daily before work starts, as needed throughout the shift, and after any event that increases hazards such as rainstorms. Water saturates soil, adds weight, and dramatically raises cave-in risk. If hazards are found, workers must be removed until corrections are made.
