PG&E technicians began purging gas from distribution lines Saturday night in the Glenview neighborhood of southern San Bruno in an
effort to restore gas service after a massive explosion in the city on Thursday.
The expulsion of gas from the transmission system is being done to clear the pipelines and test their integrity, PG&E said in a statement
through a San Mateo County non-emergency alert system.
During the testing and emission – which is expected to take several hours – residents living near the impacted neighborhood may smell gas
in the air, but it is not cause for alarm, the statement said.
“This is a safe and standard restoration practice,” the statement said.
Anyone with questions about the purging of the gas is encouraged to call PG&E at (800) 743-5000.
A ruptured 30-inch steel gas pipeline near San Bruno Avenue and Skyline Boulevard caused an explosion at about 6:15 p.m. Thursday that sent a fireball shooting into the sky.
The ensuing fire raged through the crowded Crestwood Canyon residential area well into Friday morning, destroying 38 homes and damaging 7 others.
As of Saturday evening, seven people have been pronounced dead from the fire and another six are still missing, according to San Bruno
The National Transportation Safety Board and PG&E are both investigating claims by residents of the neighborhood that they reported
smelling gas in the air prior to the fatal pipeline explosion.
