A fire alarm forced students to evacuate DeBartolo Hall briefly Monday morning.
The alarm went off at 11:10 a.m. and students and faculty were allowed back into the building at 11:23 a.m. after fire fighters signaled the area was clear. Classes resumed normally after students returned to the building.
Bruce Harrison, Notre Dame Fire Department fire chief, said the call was smoke-related, due to smoke in the ventilation system of the building. There was no fire, Harrison said.
Harrison said maintenance work on the heating and air conditioning system caused the smoke.
Students began to smell smoke in their classrooms shortly before the alarm went off.
