Over a dozen fire departments responded to a four-alarm fire that extensively damaged a house near Grayslake and displaced several residents Wednesday evening.
The Grayslake Fire Protection District responded around 6:05 p.m. Wednesday to the 18100 block of West Twin Lakes Boulevard in unincorporated Grayslake for a report of a structure fire.
Grayslake Fire Protection District Battalion Chief David Torkilsen said Grayslake firefighters and Gurnee firefighters arrived simultaneously.
They found heavy flames coming from the rear of the residence.
Fire crews initially went to a “defensive fire attack” to knock down the large body of fire from the outside, Torkilsen said.
Firefighters then entered the home through the front door to complete a search of the residence.
No one was found inside the residence and crews began conducting overhaul operations by extinguishing hidden fires.
The incident was upgraded through the Mutual Aid Box Alarm System (MABAS) to the fourth alarm level.
Five residents of the home were displaced as a result of the house being left uninhabitable, Torkilsen said.
No injuries to any occupants or firefighters were reported.
The Grayslake Fire Protection District was assisted by Gurnee, Newport, Round Lake, Zion, Highland Park, Lake Villa, Fox Lake, Countryside, Wauconda, Beach Park, Waukegan, McHenry, Barrington, Lincolnshire-Riverwoods and Long Grove fire departments.
The cause of the fire remains under investigation.
