Facility 1F, the first floor of the Ibis Island complex, served as the primary entrance to the research facility. The research facility's administrative offices were located on this floor, as was a lecture hall often used by Edward Kirk, the facility's lead researcher and supervisor. Despite being the most easily accessible floor of the facility, each part of the floor was heavily secured by a combination of locks, laser shutters, and DDK doors. Immediately inside the main entrance of the facility was a security checkpoint, which guarded the military's strategy room, a toilet, the first floor's primary control room, and a stair leading to floor B1.
