About 20 people were evacuated in San Mateo Tuesday morning as crews sealed a small gas line break, a PG&E spokesman said.
People were evacuated from buildings in the area of West 20th Avenue and Alameda de las Pulgas after the gas line break was reported at 10:25 a.m., PG&E spokesman Jason King said.
A construction crew hit a 1.25-inch plastic gas line with an excavator there, causing the leak, King said.
PG&E sealed the gas leak at about 10:50 a.m. and the evacuations were lifted, he said.
There were markings on the ground where the underground gas lines were and PG&E is investigating why the crew hit the line despite the markings, King said.
“It’s important to not only call 811 but to follow the safe digging instructions provided,” he said.
No customers lost service because of the rupture.
