Academic and Administrative buildings and facilities are accessible to members of the campus community, guests and visitors during normal hours of business (Monday - Friday). This excludes holidays. Faculty and staff who wish to enter their office or support areas during non-work hours are asked to notify or visit the Department of Public Safety. This will alert security in case of an emergency in the facility. Department heads are requested to submit after hours authority lists to the Department of Public Safety for personnel assigned to their respective departments with special access needs. Access to residence halls is limited to Gettysburg College students, their guests and authorized staff, and are secured twenty-four hours a day.
