BWI control tower evacuated briefly after fire alarm

LINTHICUM, Md. (AP) - An official says the air traffic control tower at Baltimore-Washington International Thurgood Marshall Airport was evacuated briefly after the fire alarm went off.

Airport spokesman Jonathan Dean said in an email that the airport's fire department responded to a report of a fire alarm at the tower about 6:45 a.m. Tuesday and investigated. He says firefighters didn't find smoke or fire.

Dean said late Tuesday that a water flow alarm went off as a fire suppression system was coming back on line after a construction project. He says corrective measures have been taken.

Dean says tower functions were suspended briefly but personnel returned to work about 15 minutes later.

Dean didn't know how many flights were delayed, but he says the overall effect was minor.
