A nail salon is unoccupiable after a fire, which was quickly extinguished by firefighters, broke out inside the business in a strip mall in Mundelein early Sunday morning.

The Mundelein Fire Department initially responded around 5:10 a.m. Sunday to Quick Pick Liquors, 635 North Midlothian Road in Mundelein, for a fire alarm activation.

“Crews also went into the adjacent units to ensure that there was no fire extension and it did not extend past the unit of origin,” Lockwood said.

The strip mall was empty at the time, and no injuries were reported.

Lockwood credited the fire alarm system with giving firefighters a valuable head start in containing the blaze.

“It gives us early notification. Generally, that is the purpose of the fire alarm, so it did its job in this case, and we were able to get here early and extinguish the fire before it grew and extended into other units,” Lockwood said.
