ARLINGTON, Kan. (AP) -- A grain elevator has exploded in south-central Kansas, injuring one worker.

The explosion was reported about 7:25 a.m. Thursday at the Cairo Coop in Arlington, which is about 15 miles southwest of Hutchinson.

Reno County Sheriff Randy Henderson said one employee was taken to a Wichita hospital with burns that appeared to be minor.

Bill Guy, Reno County emergency management director, said the injured employee was at the base of the elevator when the explosion occurred. He said another employee was at the grain elevator at the time, but was not hurt.

He said it was unclear if the elevator was full and the cause is under investigation.

Fire crews were also moving a crane to the scene to assess the explosion site.
