There were no injuries in a 2 alarm fire Sunday, April 25th, in a multi-tenant commercial building in the 12000 block of Aero Drive in unincorporated Plainfield. The Plainfield Fire Protection District was dispatched at 9:18 pm for smoke showing in the area of the building. Upon arrival firefighters observed smoke coming out of one of the units of the multi-tenant building and forced entry and found a fire. The response was immediately upgraded from a smoke investigation to a structure fire. Firefighters began fighting the fire from the interior of the building and upgraded the response again to a box alarm but were eventually forced for safety reasons to an exterior firefighting operation because the roof was going to collapse. There are no fire hydrants in this area so the response was upgraded again to a 2nd alarm in order to bring in more fire tenders to transport water to the scene. Route 59 and also 119th Street had to be shut down during the firefighting operation to protect the fire hoses running across the roadway and for the shuttling of water during the tender operation. The building is uninhabitable and the cause of the fire is under investigation. Assisting the Plainfield Fire Protection District with fighting the fire, and responding to other calls during the fire, were the following Fire Departments: Aurora Township, Bolingbrook, Bristol-Kendall, Channahon, Darien-Woodridge, East Joliet, Elwood, Lemont, Lisbon Seward, Little Rock Fox, Lockport, Minooka, Montgomery, Morris, Naperville, New Lenox, Oswego, Rockdale, Romeoville, Troy, Wilmington and York Center.
