Georgia Tech university was evacuated after a minor explosion in a laboratory.
Public relations director Lisa Grovenstein said no one was injured during the noon blast at the Ford Motor Co. environmental science and technology building which also houses classrooms.
The university's emergency notification system was activated by accident after the explosion, sending e-mails, text messages or voicemail to everyone on campus, she said. A follow-up notice was sent letting the campus know that the notification was a mistake.
The university and the Atlanta Fire Department were investigating the cause of the explosion.
