Trench Hazards. 3-2. Injury and Death. Unprotected trenches and excavations can be hazardous. Most accidents occur in trenches 5-15 feet deep. There may be no warning before a cave-in. Asphyxiation. Each time a breath is exhaled the weight of the load restricts inhalation of the next breath. Slow suffocation usually follows unless rescue is immediate.. WHAT CAUSES DEATH?. SOIL WEIGHT.

The bones of several other individuals soon emerged from the peat bog. It would be determined that the human remains uncovered at Windover were between 7,000 and 8,000 years old, making them 3,200 years older than King Tutankhamen and 2,000 years older than the Great Pyramids of Egypt. This was just the beginning of an archaeological adventure that continues today.“Windover is truly a unique site that continues to astonish. Dr. Wentz does a wonderful job of telling the two stories of Windover. One is the story of the people who lived in the area and are buried in the pond. The other story introduces you to the amazing people and circumstances which made the excavation possible. From its discovery by a backhoe operator and a concerned and interested landowner to the crew who worked on the project, Wentz effectively captures the stories of a fascinating archaeological discovery.” Many Proximal Fault Sources and Susceptible Sediments.
