Dallas airport offices turn smelly

DALLAS, June 3 (UPI) -- The two-story administrative office building at Dallas/Fort Worth International Airport was emptied for a time Tuesday because of a bad odor, authorities said.

Employees returned to work later in the afternoon after emergency personnel used a large fan to air out the offices, The Dallas Morning News reported.

Authorities said the source of the "suspicious" smell was probably material put into the sewer system to alleviate a bad odor, the newspaper said.

The episode, which attracted fire trucks and other emergency vehicles, interrupted a noontime meeting of a committee of the airport's board of directors. Employees and visitors, who were kept outside until public safety officials gave the all-clear signal about 1:15 p.m., could still detect a slight smell when they returned, the News said.
