The third floor of a building on the National Naval Medical Center campus was evacuated around 2:30p.m. Wednesday after reports of a suspicious odor, according to Montgomery County Fire and Rescue.

A county hazmat unit as well as federal NavyMed rescue personnel responded. The third floor of the building -- Building 70 -- was ventilated after a product was found to have spilled inside a chemical closet in a lab area, according to Capt. Oscar Garcia, a county Fire and Rescue spokesman. Garcia didn't know what the product was, though he said it appeared to have been stored properly.

No one was injured or taken to the hospital. "Our role was very limited -- they pretty much had it under control," Garcia said.
