Received call from the public on 2/11/15 reporting gas odor at 7 bandon circle, westford, ma. Fire department arrived first and reported gas blowing at meter.

The riser was not accesible due to the fire and the service shutoff was buried under snow and was also too close to fire. Gas was shut off at the main at approximately 1:00 pm. It was determined that the regulator was damaged by falling ice from the roof which caused the release of gas.
