No one was injured in a fire that broke out in a vacant building at the former Hunters Point Naval Shipyard in southeast San Francisco, but the cause remains under investigation, firefighters said Friday.
The San Francisco Fire Department was alerted to the fire in Building 500, a vacant structure at Manseau Street and Third Avenue, around 3 a.m. Wednesday, according to the U.S. Navy’s Base Realignment and Closure Program Management Office.
Building 500 was a World War II-era wooden structure that served as administrative offices for the Naval Radiological Defense Laboratory, a military research facility that operated from 1946 to 1969, according to the Navy.
No hazardous materials were stored in the building, and it was empty and unused at the time of the fire, the Navy said in a press release.
“While this building was intended to be surveyed further for very low-level radiological isotopes, based on historical use of the building and historical surveys, there is no reason to expect smoke or dust from the incident would result in exposure different than from any standard building,” the Navy said.
