Two people were critically injured this afternoon after a scaffolding fell from a building in the SOMA neighborhood.
Authorities told KTVU that the two workers were installing scaffolding at a 27-story office building located at 350 Mission Street when it collapsed. One worker fell some 40 feet and the second worker fell about 30 feet, fire spokeswoman Mindy Talmadge said.
The workers were rushed to San Francisco General Hospital with life-threatening injuries.
Meanwhile, police have blocked off traffic at various intersections in the area.
"The intersection of Fremont and Mission Streets is closed. Fremont Street between Mission and Market Streets is also closed, and Mission Street between Fremont and Beale is closed," Sgt. Danielle Newman told us.
