Fire crews were called to a band competition at Lower Dauphin High School on Saturday night after someone reported seeing smoke in the building.
According to officials, the incident was caused by a smoking "exit" sign.
With the school full of people, fire crews wanted to get everyone out, just to be safe. No one was injured, and people were allowed back inside the building a short time later.
