Government Office, Government/Military Norfolk, MA – Fire from gas explosion at District Attorney’s office contained with help from sprinklers February 25, 2015 viking210 A gas explosion and fire early Sunday at Norfolk District Attorney Michael W. Morrissey’s Canton offices was “held in check by outside master streams and operating sprinkler heads,” Canton fire Chief Charles Doody said. Doody said firefighters secured vital records and evidence once they were able to stabilize the office building, which shares the Shawmut Industrial Park with the separately housed Norfolk Probate and Family Court. Doody said the office building’s roof was recently cleared off, leaving gas meters buried “under several feet of snow.” Around 1:50 a.m. yesterday, gas backed into a mechanical room, ignited and exploded, severely damaging a wall shared by the first and second floors.
