Fire units were dispatched to a Clinton Avenue address at 18:29 hours for smoke coming from a vacant house. A neighbor on the “C” side of the structure had just arrived home and noted smoke coming from the chimney of the three story class five structure. Arriving fire units found heavy smoke issuing from the chimney as well as dark stained windows on the first floor. Thick brown smoke was issuing from cracks around all of the doors and windows. The working fire signal was transmitted and Engine 5 was ordered to take a water supply and stretch in with their attack line. Truck 7 setup on side A and laddered the structure. A second alarm was quickly transmitted bringing one engine from Plainfield and one Truck from New Market to the scene. Fire had burned through the first floor and extended upward. Three lines were put into service. All searches were negative. The structure was found to be a vacant building in the process of being rehabed by the owner. The fire was put under control and turned over to the fire inspectors for origin and cause investigation. DC Campbell in command.
