摘要

On August 14, 2010, Michael A. Diehl, dredge operator, age 23, drowned while attempting to retrieve a small boat from a dredge pond. The boat was on a trailer, which was being pulled up a ramp from the dredge pond, when the boat dislodged and drifted back into the dredge pond. The accident occurred because management failed to ensure that persons wore life jackets while working around water. Diehl was not wearing a life jacket when he swam into the dredge pond. Investigators concluded that Diehl hit his head while attempting to climb into the boat.
