    NTSB Continues Investigating Gas Line Explosion in SF

    As the NTSB looks into why it took so long for PG&E to shut off the gas during Wednesday’s fire near the USF campus, they discovered the shut off valves weren’t under the pavement even though PG&E said they were. Jean Elle reports.

    A National Transportation Safety Board team is now investigating a gas line explosion in San Francisco.

    About 300 residents in the city's Lone Mountain neighborhood remain without gas following the explosion and three-alarm fire Wednesday.

    Crews are working to repair some of the damage caused by the fire as well as to restore the electricity to all of the 2,500 customers who lost power. Crews are now focusing on removing water and debris from the line before gas service can be returned, she said.

    The incident, first reported at about 1:10 p.m. near Geary Boulevard and Parker Avenue, left two buildings with major structural damage and three others with extensive water damage, according to police and fire officials.

    Flames shot in the air for more than two hours before crews stopped the flow of gas at 3:36 p.m.

    Third-party contractors working on fiber optics struck a 4-inch gas line, causing the rupture and subsequent explosion and fire, PG&E officials said.

    Mayor London Breed confirmed Wednesday that no one was injured.

    It was not immediately clear how many residents or businesses have been displaced.

    Menniti said the contractors had called 811 to check for any utilities underneath the area before they started digging. PG&E crews then sent a locator to the scene on Jan. 28 and made markings in the area, she said.

    A reason for the breach despite the markings remains under investigation, she said.
