SAN FRANCISCO – San Francisco Municipal Transportation Agency’s headquarters has been given the all-clear after it was evacuated Friday. Occupants reported an irritating gas or substance in the building, a San Francisco fire spokeswoman said.
According to SFFD, people were let back into the building at 4:15 p.m.
After 3 sweeps of the heating and ventilation systems, they were unable to discover the source of the irritant.
All 34 people that required some type of medical attention at the scene refused transport to a hospital.
Firefighters were called to 1 South Van Ness Ave. at 3:07 p.m., fire department spokeswoman Mindy Talmadge said.
When they arrived, building occupants were already evacuating the building themselves, Talmadge said.
The source of the irritant remains under investigation, but firefighters have called in a hazardous materials team and turned off the building’s air conditioning and ventilation system, Talmadge said.
She noted that the building, a high-rise that houses both the SFMTA and other city agencies, holds a large number of people and the evacuation has produced a large crowd on the street.
“I would avoid Market and South Van Ness right now if I were you,” she said.
SFMTA spokeswoman Kristen Holland said a building alarm went off around 3:10 p.m. and she and others were evacuated out of the building.
