Dallas/Fort Worth Airport evacuated its administration building early Tuesday afternoon, after a strong chemical smell began to permeate the building.
After using a large fan to blow air through the building, D/FW officials gave the clear sign at 1:20 p.m. for people to re-enter the building.
One airport official said the smell could be related to the cleaning of sewers underneath the building. A few people reported feeling nauseous because of the odor, but nobody was transported to hospitals, airport officials said.
D/FW dispatched emergency crews to set up a large blower that cleared the air out of the building.
At least 100 people were standing outside in the building in the parking lot and underneath trees in the shade while the crews worked early Tuesday afternoon.
The incident interrupted the Airport Board's committee meeting.
