A construction engineer at the Texas National Utility Commission died after an accident at a transmission line near Dallas on Saturday, the agency said.
The National Transportation Safety Board said in a statement that it was looking into the circumstances surrounding the accident that occurred Saturday morning at the 6.1-mile (11-kilometer) Texas Southern Transmission Line (TSL) near Fort Worth.
Officials did not release the engineer’s name.
The NTUC said the engineer was “in the process of installing equipment at a construction site” when he fell off the transmission line and hit his head.
He was taken to the hospital for evaluation and pronounced dead on arrival, the NTUC statement said.
It did not say when the engineer worked for the NTPC.
In 2012, construction workers on a Texas Southern line went through an inspection before starting construction.
The agency said that during that inspection, the engineer noticed that there were problems with the installation of the cables that run from the transmission tower to the substation.
A safety video showed a man walking around the construction site, trying to locate the missing cables.
The video shows him trying to work on one of the missing wires, then walking away.
The video shows that the cable is missing and that he is trying to reach the missing cable.
Then, the video shows the man walking back around the missing wire, and then falls on the wire.
A construction worker is seen running from the area and being interviewed by police.
