If a violent incident or some other incident occurs outside your building, stay inside or shelter-in-place. If there is an imminent threat of violence, the entrance doors should be locked by those designated to carry out a lock down in your building. In addition, lock classroom or office doors, if possible and hide from view of windows. The university may initiate a modified lock-down where the doors are locked, but normal academics and operations continue. An atmospheric release may also warrant staying inside, in which case, move to the highest location in the building away from windows and doors.
