Thanks for all the
clean, safe, reliable, occasionally dangerous as hell energy:
A series of gas explosions an official described as "Armageddon" killed a teenager, injured at least 10 other people and ignited fires in at least 39 homes in three communities north of Boston on Thursday, forcing entire neighborhoods to evacuate as crews scrambled to fight the flames and shut off the gas. Massachusetts State Police urged all residents with homes serviced by Columbia Gas in Lawrence, Andover and North Andover to evacuate, snarling traffic and causing widespread confusion as residents and local officials struggled to understand what was happening.
The Massachusetts Emergency Management Agency blamed the fires on gas lines that had become over-pressurized but said investigators were still examining what happened. Columbia had announced earlier Thursday that it would be upgrading gas lines in neighborhoods across the state, including the area where the explosions happened. It was not clear whether work was happening there Thursday, and a spokeswoman did not return calls.
One of the (many) drawbacks to using natural gas is that "all" lines require pressure, and that pressure is relative to the size and distance the gas must travel. The big pipelines require an extreme amount of pressure, which is one of the things that make them so dangerous. But even small lines that serve individual homes or businesses require pressure, and just a modest increase can result in fugitive emissions (leaks). And when those gas lines have been in place for decades, the danger becomes much more acute:
