In the fall of 2010 I participated as an incident investigation board member to determine why a light-duty steel lattice structure collapsed, resulting in an injury. Shortly after this accident took place, our investigation team met with and interviewed the crew members who were at the work site that day. One crew member in particular still remains firmly embedded in my memory. During his interview he was very emotional while he described the sequence of events that led to the collapse of the steel lattice structure and the injury to his co-worker. He ended his testimony by stating, “Please tell me what happened. I don’t know what happened. I’d like to know what happened.” We left the interview assuring the crew member that we would find out what had happened.
