The East Boston gas surge was a series of fires and at least one explosion that took place early on the morning of September 23, 1983. An underground control that regulated the flow of natural gas failed, causing a surge of the fuel into the neighborhood of East Boston, Massachusetts. [1]
The sudden swell of gas rushed into businesses and residences, increasing the size of pilot lights to as much as a foot high. A number of fires started as a result and the second floor of one building in the Central Square area exploded. [2]
Between 3:15 am and 8:00 am, 9-1-1 operators received approximately 170 calls reporting fires and the smell of gas. People rushed into the streets, and McClellan Highway and the Callahan Tunnel were closed to incoming traffic with the exception of emergency vehicles. [3]
By mid-morning, the fires had been extinguished and the gas problem was fixed. The Boston Gas Company later said that a broken water main had flooded a gas regulator, causing the surge. There were no reports of injuries or deaths. [4]
A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane. In industrial explosions many other gases, like hydrogen, as well as evaporated (gaseous) gasoline or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition, or use of alternative energy.
On March 12, 2014, an explosion occurred at 9:31 a.m. in the East Harlem neighborhood of Manhattan in New York City, United States. The explosion leveled two apartment buildings located just north of 116th Street at 1644 and 1646 Park Avenue, killing eight people, injuring at least 70 others, and displacing 100 families. City officials initially pointed to a gas leak as the cause of the blast. In June 2015, the National Transportation Safety Board (NTSB) blamed the explosion on failures by Consolidated Edison and the city. The NTSB also agreed to review Whistleblower Gas Explosion Audit Findings from the 2009 Floral Park Queens gas explosion as part of their East Harlem Gas Explosion Investigation. The NTSB were unable to resolve these hazards found with merit by the New York State Public Service Commission (NYSPSC) and they remain a Public Safety Hazard today.
On September 13, 2018, excessive pressure in natural gas lines owned by Columbia Gas of Massachusetts caused a series of explosions and fires to occur in as many as 40 homes, with over 80 individual fires, in the towns of Lawrence, Andover, and North Andover, all within the Merrimack Valley, in Massachusetts, United States. One person, 18 year old Leonel Rondon, was killed and 30,000 were forced to evacuate their homes immediately.
