A building that houses several city departments, including Human Resources and the San Francisco Municipal Transportation Agency, were evacuated late this afternoon after two dozen people complained of throat irritation.
Fire crews were called at about 3:07 p.m. to 1 South Van Ness on reports of a possible Hazmat situation. When they arrived, employees were already evacuating the building, said Mindy Talmadge, spokeswoman for the San Francisco Fire Department.
The people complained of symptoms related to an irritant of some sort. "Most were complaints about throat irritations," Talmadge told us.
Fire crews treated 34 people at the scene, all of whom refused to be transported to the hospital. Firefighters closed Van Ness to cars for over an hour while they did multiple sweeps of the building.
At about 4:14 p.m., fire officials determined the building was safe, and no hazmat was detected.
"Whatever it was dissipated," Talmadge said.
