Two workers trapped in Oklahoma dam after explosion – fr


Two workers were trapped Thursday night at an Oklahoma dam after an explosion, a dam agency official said.

The explosion just before 6 p.m. at the Kerr Dam near Salina did not compromise the structure, said Justin Alberty, spokesperson for the Grand River Dam Authority.

The contractors were about 80 feet from the top of the dam and were doing routine core drilling when they were trapped, he said.

“Right now, the priority is to reach them, to reach out to those two people,” Alberty said.

Alberty did not have details of their conditions or how they were trapped. He said they were in an inspection gallery when the explosion occurred, and he believed officials had been in contact with them at some point.

There were three contractors at the scene at the time of the explosion, and one was able to get out. This worker initially refused treatment, but was later taken to hospital for examination, Alberty said.

Drilling of core samples in bedrock below the dam has been described as part of a routine dam safety program.

Alberty said there may have been a pocket of natural methane, but warned the cause of the explosion has not been determined.

The Kerr Dam is located at the southern end of Hudson Lake in County Mayes, southwest of Salina.
