Seven construction workers and one firefighter suffered minor injuries after a fire broke out at a building under construction at San Francisco General Hospital on Tuesday morning, a Fire Department spokeswoman said.
The one-alarm fire was reported at 9:32 a.m. in an elevator shaft on the seventh floor of the building at 23rd Street and Potrero Avenue, Lt. Mindy Talmadge said. It was controlled at 10:18 a.m., she said.
Seven workers suffered smoke inhalation and one was hospitalized. A firefighter sustained a minor injury to her arm, Assistant Fire Chief Tom Siragusa said.
Hospital spokeswoman Rachael Kagan said the new building is slated to open at the end of 2015. She did not know the extent of the damage from the fire or whether it would affect that timeline.
However, Siragusa said he does not believe the damage will cause any significant delays to the project.
Kagan said this is the first problem that has occurred since construction started.
"We're very relieved no one was seriously hurt," she said.
The blaze did not affect hospital operations, Kagan said.
The fire prompted the closure of Potrero Avenue between 22nd and 24th streets.
The cause of the fire is under investigation. Talmadge said crews were doing "hot work," or welding, in the shaft before the blaze broke out.
The flames were confined to the shaft, Siragusa said.
The California Division of Occupational Safety and Health has been notified about the fire, she said.
