Consequence: The system may be damaged (source states an equipment-damage consequence only — no personal-injury language)

Avoidance: Be extremely careful not to allow the front cover to come into contact with the ceiling or the patient couch when the gantry is tilted with the front cover open; check clearance against Figure 6.3-2 before commanding a tilt while the cover is still open
