All employees evacuated safely after a fire broke out at a manufacturing plant in Lake in the Hills, sending heavy flames through the roof Monday afternoon.

The Algonquin-Lake in the Hills Fire Protection District responded around 4:38 p.m. Monday to AFC Materials Group, 14 Walter Court in Lake in the Hills, for a report of a structure fire.

Algonquin-Lake in the Hills Fire Protection District Deputy Chief John Knebl said firefighters arrived on the scene and found a single-story manufacturing plant.

There was heavy fire coming from the roof of the building, Knebl said.

Firefighters initiated an “aggressive fire attack” on the structure and positioned a ladder to the roof for extinguishment.

Knebl said additional fire companies on the scene checked the building for fire extension.

The facility’s employees were able to evacuate safely and no employee injuries were reported.
