SAN FRANCISCO (KCBS) – San Francisco firefighters were called to a possible hazardous materials situation Thursday at Saint Francis Memorial Hospital.

Five postal workers sought treatment at the hospital for symptoms that had developed over the last couple of days, said SFFD Lt. Mindy Talmadge.

The workers went to the hospital on the advice of their supervisor, Talmadge said, adding that it was unclear what they may have been exposed to at the nearby post office.

“There’s no immediate exposure to anything that we’re aware of, but as a precautionary measure, we’re testing whatever we can locate,” she said.

A San Francisco Fire Department hazardous materials team went to the hospital at 900 Hyde St. between Pine and Bush streets shortly after 11:30 a.m. to decontaminate the workers’ clothing.

Talmadge said the workers were cleared to return to work. She did not elaborate on their symptoms, but said they were not seriously hurt.

Fire crews were working with officials from the San Francisco Department of Public Health to determine what may have caused the workers’ symptoms.
