MA – Massachusetts regulators will review natural gas explosions across the state, as two people have been killed in three blasts over the past three months.

Robert Keough of the Executive Office of Energy and Environmental Affairs said the Department of Public Utilities wants to rule out a potential pattern about which authorities should be concerned. Although, Keough has said that he does not believe it to be the case.

Over the past five years, Massachusetts has seen a total of 12 gas explosions.

The three house explosions over the past three months — in Gloucester, Scituate and Somerset — have been linked to gas by some, including neighbors at the scene.
