Officials from the Occupational Safety and Health Administration said the 15-foot-deep trench was unsafe and lacked safety protections in the area where the two workers were digging a sewer line at the time of the collapse. According to OSHA, trenches of that depth should be protected by sloping the walls or strengthening the sides with a shield or shoring materials to prevent a collapse.
OSHA is continuing to investigate the cause of the fatal construction accident.
