SAN FRANCISCO — More than a dozen homes were evacuated Thursday after a 2-inch plastic gas pipe ruptured in the same San Francisco suburb where a pipeline explosion killed eight people in 2010.
The distribution main line burst around 10:45 a.m. when a private contractor working for the city of San Bruno struck the pipe with a backhoe in the Crestmoor neighborhood, at the same intersection where the previous blast occurred, Pacific Gas & Electric Co. spokeswoman Brittany Chord said.
PG&E crews were on-scene by 11 a.m. and stopped the gas flow in less than half an hour, Chord said.
"We worked very closely with our first responders on the scene to shut the gas off as quickly as possible," Chord said.
She added the line was not fitted with excess flow valves, which are designed to trip automatically when there is a break in a distribution line, the narrow-diameter pipes that serve individual homes and businesses.
