Investigation Summary

On October 27, 2006, an employee was working for a communications company in a controlled environment vault (CEV) that measured 10 ft wide by 20 ft long by 18 ft deep. Access and egress to the space was provided by a fixed vertical ladder located on the vault wall. As the employee descended the ladder, an extremely loud noise that was unexpectedly created (by a carbon monoxide blower cycling on), startled the employee. It caused him to falter, loose his grip, and fall approximately 15 ft onto the vault floor. The employee suffered a fractured bone in his upper arm and was hospitalized.
