No serious injuries in West Chicago fire

There were no serious injuries, but one West Chicago firefighter was treated for heat-related symptoms Monday as crews battled a blaze at a home-based insurance company on the 100 block of Grand Lake Boulevard, authorities said.

The cause of the fire at the Integrity Insurance Agency is still under investigation, but firefighters said they believe it may have been sparked by an electrical problem. It appears the fire started outside the building and traveled into the attic.

Firefighters said they responded at 10:49 a.m. and had to cut a hole in the roof, break windows and pull down some of the siding to extinguish the blaze.

One person was in the house at the time of the fire but escaped without injury, Deputy Chief Steve Lakics said. One firefighter suffered from heat-related symptoms.

“It’s hot and humid out there,” Lakics said, “which requires more firemen and rotating companies.”

Lakics said the fire was small and the damage is “repairable.” He said the fire did not cause much structural damage.

Firefighters left the scene around 1 p.m.
