A rescue operation has been launched after two workers were trapped in an Oklahoma dam following an explosion, according to reports.
The blast, at Kerr Dam near Salina, happened as the contactors were doing routine core drilling about 80ft down, according to Justin Alberty, a consideration for the Grand River Dam Authority.
He did not have details on their conditions or how they were trapped, according to Tulsa‘s KJRH-TV.
“Right now the priority is to get to them, to get down to those two individuals,” he said.
The authority said three workers were testing the bedrock below the dam before the explosion, according to News on 6.
While they were working, some kind of explosion occurred and trapped two of the three in a shaft. One man was able to get out but two remain trapped, it’s reported.
