Diesel exhaust from a construction lift caused a partial evacuation of the state Department of Motor Vehicles headquarters in Sacramento.
A lift being used in refurbishment of the building sent fumes through an air intake and into offices on the third floor of the six-story building at 24th Street and First Avenue.
Some of the employees on the third floor were evacuated about 10 a.m. and the Sacramento Fire Department was summoned. Employees are now back to work, a DMV spokeswoman said.
Two employees went to the hospital after breathing in the fumes.
