Villa Park Fire Department officials said no one was injured when oily rags ignited late Monday at a business that specializes in cleaning restaurant linens and uniforms.

Firefighters were called to the business on the 1000 block of North Villa Avenue just before 9 p.m., Chief Ron Rakosnik said.

Firefighters encountered smoke inside the building and a sprinkler system had been activated. Firefighters spent about an hour on scene to make sure there were no hot spots.

The business had been closed for the day and no one was inside when firefighters arrived.

Fire officials estimated about $3,000 in damage and the building did not sustain structural damage. Rakosnik said the business was expected to reopen Tuesday.
