Mass. shopping center evacuated for gas leak when snow plow clips meter

About 100 people at a shopping complex in Hanover, Massachusetts, were evacuated from multiple businesses, including Macy’s and Dick’s Sporting Goods, because of a gas leak Saturday, fire officials said.

Firefighters arrived at Hanover Crossing within minutes after multiple 911 calls reported a gas leak in the area of 1775 Washington Street around 4 p.m., the Hanover Fire Department said. Firefighters learned on scene that an exterior gas meter assembly had been struck by snow removal equipment.

Hanover firefighters urged the public to avoid the affected area and initiated an immediate evacuation after confirming there was an active gas leak with a significant vapor cloud extending from the damaged meter, accompanied by a loud roaring sound. The department recalled all of its off-duty firefighters to help.

Evacuating occupants and establishing a secure hazard zone was complicated by the size of the parking area and the numerous access points throughout the shopping complex, the department added.

Eversource responded to the scene and secured the leak, which was below the shutoff valve, about an hour after it began, fire officials said. National Grid also responded to assist with securing electrical service in the affected area.

Once the gas leak was mitigated, firefighters conducted safety checks of nearby businesses, with several requiring ventilation. All but four stores were allowed to resume normal operations within one hour of the gas leak being secured.

The evacuation was done as a precaution, according to Eversource, which said they hadn’t heard of anyone needing to be taken to the hospital.

The scene was cleared around 6:45 p.m., however Hanover Inspectional Services and Eversource remained on site to complete repairs to the damaged utilities.

The public is reminded to call 911 immediately if a gas leak is suspected, including situations involving a strong odor, visible vapor cloud, or loud hissing or roaring sound. The fire department also said that extra caution should be used when operating snow removal or other equipment near utility meters.
