Just after 3:30 Battalion Nine companies were dispatched to the 700 Block of Chestnut Street for a reported fire with elderly occupants attempting to evacuate the structure. The first arriving chiefs made sure the occupants were out of the home and attempted to knock the fire down with a extinguisher. Companies quickly stretched a line and checked for extension. Fire was brought under control within 15 minutes. The home was vented and turned back over to the residents. Companies operated on scene for just over an hour. Fire was determined to be started by a lithium ion battery on the nightstand
