A broken PG&E gas line prompted theevacuation of an office building for several hours on Monday.
A contractor digging a trench with a backhoe around 11:20 a.m. near an office building located at 1450 Fashion Island Boulevard hit a gas service line used exclusively by that building's tenants, PG&E spokesman Paul Moreno said.
The high-pressure pipe leaked gas for approximately an hour, but no gas made it into the building and no one was injured, San Mateo Battalion Chief John Healy said. Building tenants were evacuated as a precaution, Healy said.
Moreno said all repairs to the pipe were expected to be finished by the day's end.
Contractors typically hit gas lines when they are using heavy machinery, instead of digging by hand, to excavate certain areas determined by PG&E to require such a precaution, Moreno said.
