Students and faculty at Centennial Elementary, 1301 North Utica Avenue, were evacuated just before noon Thursday.
A smell of smoke was reported coming from an art room, but no fire was found.
The Lubbock Fire Department investigated the cause of the smell and confirmed that it was caused by an air conditioning unit with a burned-out motor.
All 725 students were evacuated in about 2 minutes, according to LISD spokesperson Nancy Sharp. Everyone was allowed back in the building at 12:40 p.m. and no one was injured.
Parents were notified of the incident, Sharp said. Fire
drills are done monthly at LISD schools, and Centennial Elementary had a fire
drill last week during Fire Prevention Week.
