On the day of the incident, a 36-year-old pipelayer and another worker for a water, sewer and drainage installation and repair business entered the trench to remove old pipes and install new ones. The trench had no protective system, although there was a hydraulic shoring cylinder near the bottom on one side.
The job was almost done when the victim entered the trench to nish connecting the pipes. The trench collapsed, burying him.
