The Geneva Fire Department responded to a report of a fire behind a restaurant grill at 4 a.m. May 16 at the McDonald’s located at 1812 S. Randall Road.

The first arriving engine company found flames exiting from the roof of the building, and two employees waiting outside.

Firefighters determined the fire was coming from the exhaust hood and duct work used to ventilate the restaurant’s grill area. The building’s installed fire suppression system had activated, but the fire had moved up through the duct work and outside the restaurant. The flames were extinguished within 20 minutes in both the grill and duct work.

Firefighters remained at the restaurant to investigate the cause of the fire and confirm the blaze was extinguished. Damage was contained to the vent system duct work and exhaust fan located on the roof. The Kane County Health Department and Geneva Building Division also were requested to the scene.

No injuries were reported in the incident. A damage estimate has not been determined at this time, but it is anticipated the restaurant will be closed at least through May 16 to allow time for clean-up and repairs to the system.

Firefighters from Batavia, Elburn and St. Charles provided assistance to the Geneva Fire Department.
