Pacific Gas and Electric Company says it has found no evidence that a natural gas pipeline caused a residential explosion Monday evening in Oakland.
Initial media reports indicated that a natural gas line exploded at 87th Avenue and Dowling Street, demolishing part of a home and causing serious injuries to an occupant in his early 60s.
The man, Leon Spencer, is being treated at Saint Francis Memorial Hospital in San Francisco, where his condition is listed as critical but stable, according to hospital spokeswoman Linda Gillespie.
A PG&E spokeswoman said Monday night the company believed the explosion originated inside the home and was not caused by a leak in its equipment.
Following inspections and other investigative work, PG&E on Tuesday said it had found no evidence that its infrastructure caused the blast.
“PG&E responded to the scene immediately to assist the Oakland Fire Department and to perform a thorough leak investigation of PG&E pipelines in the immediate area,” company spokeswoman Brandi Ehlers said. “We did not find any indications of a gas leak on our facilities in the immediate area.”
The Oakland Fire Department is continuing to investigate the cause of the blast, according to Battalion Chief Adrian Sheppard.
“A determination is still under investigation,” Sheppard said. “PG&E has determined that it’s not associated with their equipment.”
A natural gas pipeline exploded in San Bruno in September, killing eight people and destroying dozens of homes.
