A 39 year old male plumber's helper died from injuries incurred when an excavation collapsed while re-installing a sewer line at a construction site for a new home being built. The victim was in an un-shored, vertical-walled excavation, replacing a sewer pipe that had been installed nearly a week prior to the incident. While he was shovelling dirt above the pipe to prevent future breakage, a 2' x 3' concrete caisson/footer fell in the excavation along with the surrounding excavation wall, burying the victim to his knees with dirt, striking him in the abdomen, and pinning him to the remaining wall of the trench. The victim sustained severe internal injuries to the abdomen and pelvic area, and died the following day in the hospital. Employers may be able to minimize the potential for occurrence of this type of incident through the following precautions: 1. Shore vertical wall excavations to OSHA standards. 2. Establish quality control procedures to minimize reworks. 3. Improve hiring practices for short-time workers.
