Excerpts from the ChicagoTribune.com:

A fire was reported shortly after 5 p.m. at the former Harvey’s Marathon gas station at Oakton Street and Northwest Highway in Park Ridge on Wednesday afternoon. Heavy black smoke covered the immediate area while firefighters from several communities worked to get the fire under control.

A Niles firefighter and a Schiller Park firefighter suffered minor burns while fighting the fire and were treated and released from Advocate Lutheran General Hospital.

The building was loaded with approximately 90,000 pounds of calcium peroxide, a hazardous material that can be used as a decontaminate in soil. The material was brought to the building the previous day. The station has been vacant for several years.
