PRATT, Kan. (AP) — A federal workplace safety agency says it’s investigating two recent injuries at a southern Kansas wind farm.

The Occupational Safety and Health Administration said in a release Friday that it’s investigating injuries involving workers at the Ninnescah Wind Farm in Pratt County.

OSHA says a preliminary report shows a 26-year-old employee of Blattner Energy was struck in the head by a bolt while he was working on a wind turbine at the site near Pratt on Wednesday.

Blattner Energy Inc., which is based in Avon, Minnesota, didn’t immediately respond to a call seeking comment Friday.

Another man was also injured earlier this month when he fell 120 feet while working on a wind turbine at the site. OSHA says he was employed by another company working at the site.
