Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be stored in its holding site, a 4 m x 4.5 m x 2.5 m windowless room, 2.3 km from Site 17. No less than three Level 2 personnel are to remain on site at any given time, at least one but no more than two of which being blind or visually impaired. All personnel must pass a physical aptitude test for operating whilst blindfolded.
While in storage, SCP-XXXX is to remain facing away from the single doorway. The subjects posterior ventral corners are to be bolted to the floor at all times. The object's anterior side is to remain under pressure within the range of 600 kPa and 1.1 mPa when not in use. Under no circumstances are nails to be inserted to the object, nor are existing nails to be removed. Any holes observed on the object's surface are to be caulked with an opaque sealant.
Description: SCP-XXXX is a cubic wooden crate, measuring 1.25 m on all sides. On each lateral side, the words "buckwheat cereal1" are stamped in black ink. Each side is comprised of four oak wood planks, with the anterior and posterior boards running perpendicular to the lateral and dorsal sides.
When sealed, SCP-XXXX poses no danger to the world at large. If the contents of the box are viewed directly, the observer will enter a spastic state, and will seemingly attempt to break line of sight. During this time, the observer will experience a period of heightened, irregular heartbeat as well as complete disregard for outside stimuli. Subjects exposed to SCP-XXXX for periods in excess of █ seconds will experience symptoms consistent with a transmural myocardial infarction.
After exposure to SPC-XXXX, subjects will show signs of paranoia, and will refuse to open their eyes. Over the course of approximately three days (on average, 68 hours), the subject will return to their senses. If coaxed or forced to open their eyes, subjects show no signs of visual deterioration, and will pass a ophthalmological test with similar results to their last test taken.
Photographic and acoustic surveys suggest SCP-XXXX is completely empty.
SCP-XXXX was recovered from a cargo freighter in ██████, New Jersey. Improper handling caused its front to become dislodged, causing two dock workers to become hospitalized. A third Class-E personnel was incapacitated before the object was secured. Over the course of ██ hours, the object was taken to Site 17. During unloading, a Class-D was exposed to SCP-XXXX, forcing experimentation to be postponed. The residing Senior Staff member, Dr. Q██████,
ordered the object be moved to an offsite structure, fearing a potential Keter-class memetic hazard. By serendipity, the building proved to cater to SCP-XXXX's needs well enough to become its permanent residence.
Addendum: Subjects exposed to SCP-XXXX tend to have a higher tolerance to heartbeat fluctuations. Research into applications of SCP-XXXX to treat victims of heart conditions has been postponed until further notice.
