HULL—There was a lot of smoke but no injuries during a fire at the Casey’s General Store in Hull the morning of Wednesday, Sept. 28.

The Hull Fire Department was called out to the blaze at about 7 a.m. and requested backup from the Rock Valley and Sioux Center fire departments. The latter agency brought its aerial fire truck.

The Hull Emergency Medical Services team and the Sioux County Sheriff’s Office also were at the scene, located at 612 Division St. along Highway 18.

Casey’s employees were inside the building at the time of the fire but evacuated in time to avoid harm.

“They saw that smoke was heavy, so they got out,” said Hull Fire chief Ron Hoksbergen.

The fire was concentrated in the northeast corner of the building near a storage room. Hoksbergen said the responders went into the building with fire hoses and thermal cameras, the latter of which was used to pinpoint the fire amid the smoke.

“They had a hard time finding it because there was very thick smoke,” Hoksbergen said.

The firefighters were at the site for about two-and-a-half hours.

The cause of the fire is not yet known, although the State Fire Marshal’s Office began investigating the incident Wednesday.
