Fire investigators are looking into what caused an explosion at a Kansas Department of Transportation building in northwest Kansas.
The fire broke out in Oakley around 1 a.m. Thursday. George "Pappy" Lies, Gove-Logan County emergency management director, said a large fireball flew into the air, and started a grass fire.
The wind played an issue because it spread the grass fire pretty quickly.
Crews from Lane, Logan, Oakley and Gove counties were called to help battle the blaze.
Two firefighters had be checked out at the scene, but they weren't seriously hurt.
The building housed equipment and offices, and is a total loss.
