Two out of three businesses in the building at 7585 Madison St. were damaged Thursday night by a fire that received an 18-department response and closed a portion of Madison between I-55 and Plainfield Road for three hours, Tri-State Fire Protection District Deputy Chief Jack Mancione said Friday.
Three people were transported to area hospitals. One police officer and one building occupant were transported for smoke inhalation, and one person watching the fire was transported after taking a fall. Mancione said all three were in stable condition.
Two occupants were removed from the building by firefighters during the fire.
The cause of the fire is still under investigation, Mancione said, and that investigation likely won't be complete until next week.
The 18-department response was required because of the nature of the fire and the possibility of the building collapsing, which would have made the fire much larger. Mancione said firefighters successfully contained the fire, meaning most responding units weren't active.
"Fortunately we didn’t have to go into defensive mode with our ladder trucks," the deputy chief said.
Tri-State was the lead department. They arrived at the fire around 3:30 p.m. and the fire was extinguished by 4:45 p.m.
The stretch of Madison Street around the fire was closed from 3:30 p.m. to 6:30 p.m. The building is located in an unincorporated portion of DuPage County.
The businesses in the building include an automotive services company and a seal-coat manufacturer, Mancione said.
There is also a fitness studio listed at the 7585 address.
