BNA Concourse Evacuated Twice in One Week Due to Airborne Disturbances

A noxious odor from a solvent caused the evacuation of a concourse at Nashville International Airport. The fire department conducted air quality testing and determined there were no air contaminants. The solvent was identified as Butoxyethyl Acetate, commonly used in lacquers, varnishes, enamels, and resins. The concourse has since reopened, but flights were delayed or canceled. The FAA issued a ground stop to help the airport return to normal operations safely.
