A construction accident in San Francisco that injured four workers has prompted an investigation by the Occupational Safety and Health Association (OSHA) for the state of California.
Bay City News Wire reported that the accident happened in a Nob Hill residential building where a team of workers were renovating a basement and garage.
San Francisco Fire Lt. Mindy Talmadge comments on the incident:
“They were working with jackhammers and the rock around the foundation broke away and trapped these four workers,” Talmadge said.
Three of the four had freed themselves by the time firefighters arrived. One man was trapped from the waist down in a combination of rock and dirt.
“The fire department used its shoring equipment to extricate him,” Talmadge said. “It took about 20 minutes.”
Fortunately, only minor injuries were incurred from the worksite accident.
