Firefighters are battling a four-alarm blaze at a building in San Francisco’s Portola neighborhood this evening that critically injured a construction worker, a fire spokeswoman said.
The blaze was reported at 3:47 p.m. at a building that is under construction in the 2800 block of San Bruno Avenue, fire spokeswoman Mindy Talmadge said.
Construction workers had been trying to connect a gas line and ignited the gas, Talmadge said.
PG&E crews are working to shut off the flow of gas to the building this evening, she said.
A construction worker was taken to St. Francis Memorial Hospital with life-threatening burn injuries and a firefighter was taken to San Francisco General Hospital for exhaustion, Talmadge said.
The fire spread to a neighboring building that houses a dental office and the occupants of that building were safely evacuated, Talmadge said.
