After being cleared from a previous call on the northwest side of Greenwich at about 12:50 today, Tanker 7 was re-directed to respond along with Greenwich Fire Department units to a reported structure fire on Porchuck Road - just a short distance away from the previous call. Tanker 17 and Engine 157 also responded from the station. Tanker 7 arrived soon after first arriving GFD units and supplied water to GFD Engine 8. GFD firefighters initiated an aggressive attack and made a quick knockdown using Engine and Tanker water.
