The roadways have reopened and the Los Angeles Fire Department has completed its inspection of the building and left the scene. Once county health inspectors declare the building safe for reoccupation, another BruinAlert will be sent out, university spokesman Phil Hampton said.]

A south campus building was evacuated Thursday when three facility workers encountered chlorine dioxide in a crawl space where it was not supposed to be.
The Biomedical Sciences Research Building and the area surrounding it on Charles E. Young, from Tiverton Avenue to Westholme Boulevard, have been closed while the county health inspectors and Los Angeles Fire Department inspect the building for reoccupation, said university spokesman Phil Hampton.
The three workers who discovered the gas were treated on the scene for nausea and released, Hampton said.
He said no one else was affected by the gas.
The chlorine dioxide is from a cleaning agent that a vendor was using to disinfect a lab in the basement of the Biomedical Sciences Research Building, located at 615 Charles E. Young Dr., Hampton said.
The call was made at 2:09 p.m., and the Los Angeles Fire Deparment evacuated about 150 to 200 people, Hampton said.
A BruinAlert was sent out around 3 p.m. warning people not to enter the building, and another was sent about 30 minutes later saying the area was contained.
