SALINA -The 4-alarm fire at the Flying J Truck stop on North Ohio and Interstate 70 in Salina is being blamed on the improper disposal of smoking materials.

Salina Fire Marshal Roger Williams said the plastic can used for discarded smoking materials failed and set a shed behind the main building on fire.

“The fire spread up through the soffit and into the attic space of the building,” said Williams. “The insurance company will be on site Friday to assess the damage.”

There were no injuries in the blaze.

Saline County Rural fire district 2, 5, and 7 assisted on the scene Wednesday with fire operations.

Investigators from the Kansas State Fire Marshal’s Office were called in to assist with the origin cause investigation, according to Williams.
