No one was injured in a fire Friday at a commercial building in west suburban Naperville.
About 2:31 p.m., authorities received a call about a blaze in a dust collector at a commercial building in the 1100 block of Frontenac Road, according to the Naperville Fire Department.
While crews responded, additional reports indicated that the fire was in the back corner of the building, and dark heavy smoke could be seen rising from the structure, officials said.
Everyone inside of the building had evacuated by the time firefighters responded to the blaze, officials said. Crews gained control of the fire within 30 minutes of their arrival.
No injuries were reported, officials said.
Investigators determined the cause of fire to be a mechanical failure in the company dust collector, officials said. The fire was ruled accidental.
