 Item No. SCP-303 Object Class, Euclid Special Containment Procedures As SCP-303 has not been known to travel beyond the boundaries of sight, the entire area of sight is currently considered SCP-303's containment area. All rooms in sight are to be altered where possible so as to have two entrances separated by a distance of 10 meters or a line of sight. Personnel are to be distributed evenly throughout the facility, with available radio or intercom contact, so that encounters may be resolved quickly. Personnel who witness SCP-303 are to be submitted for immediate psychiatric evaluation. All SCP objects housed at sight ██████ since before June 4, 2010 are to be transferred to Site ██████-B one at a time. Each SCP object will be transferred again to Site ██████-A once it can be verified that SCP-303 has not migrated from sight ██████ with it. Once SCP-303 either migrates to Site ██████-B or remains present at sight ██████, once all SCPs in question have been transferred to Site ████-A, containment procedures will be updated as appropriate. Description Witnesses describe SCP-303 as a nude, sexless, emaciated humanoid figure with reddish-brown skin. Instead of normal facial features, its head is dominated by an extremely large mouth, which bears a set of oversized human teeth. It continually vocalizes a wheezing noise, loud enough to be heard from the other side of most solid doors. All individuals who have had encounters with SCP-303 are capable of describing it in full, including individuals who have not physically seen any part of it. SCP-303 will periodically materialize behind any closed door, hatch or other entryway barrier opposite of sentient observer, chosen by unknown means. SCP-303 will then remain behind the door for an indeterminate amount of time. Any individual attempting to open the door or barrier experiences intense, paralyzing fear that lasts until SCP-303 dematerializes, either on its own or to avoid being directly seen by another observer. The source of this fear is not clear, but it appears to be similar in nature to Erratnophobia or Aphidiaphobia, originating on a pre-conscious genetic level. Analysis indicates that SCP-303 is not, in fact, purposely inducing fear in the affected individuals. SCP-303 does not allow itself to come into direct visual contact with any observer, and has never allowed any one individual to view more than 10% of its form. When the door or other entryway barrier is partially or completely transparent, SCP-303 will materialize in an orientation that leaves 10% or less of its body visible, or cause effects of fog or frost on the transparent surface to achieve the same effect. If SCP-303 is approached from a direction in which there is not a solid object or door breaking line of sight, it will dematerialize before direct visual contact is made. Any electronic or complex mechanical devices that SCP-303 encountered are temporarily disabled. SCP-303 has made no recorded attempt to physically or verbally engage any observer. While SCP-303 arrived at sight ██ is not known at this time, SCP-303's first recorded appearance was on March 1st, 2010. It is suspected that SCP-303 was inadvertently transferred along with or manifested by another SCP on site. All SCPs on site ██ are being re-examined accordingly. Agent ██ was showering in her private quarters bathroom when she became aware of the presence of SCP-303 on the opposite side of the shower curtain. It was wheezing extremely loudly. Startled by the discovery, she accidentally struck the shower curtain, causing it to sway outwards. The curtain partially wrapped around SCP-303, revealing that it was less than 0.5 meters from the curtain, standing erect and facing the shower. Agent ██ reports spending approximately the next three hours sobbing in the shower quietly as not to disturb SCP-303. Agent ██ reported that the wheezing stopped very suddenly, at which point in time she was able to exit the shower. Incident ██ encountered SCP-303 inside the site ██'s second floor break room. He was attempting to obtain coffee creamer from the counter cabinet when he heard loud wheezing emanating from the cabinet and was overtaken by overwhelming fear. Agent ██ later reported that SCP-303 was huddled in the cabinet in the fetal position. Agent ██ claimed to be certain of the information, despite failing to open the cabinet door. Later, when the cabinet was examined, one container of powdered coffee creamer was missing. Note, this is the first recorded instance of SCP-303 removing an object from a scene. Incident ██-303-6, Dr. ██ was discovered dead from dehydration in the second floor storage room. It is estimated that Dr. ██ spent up to five days in the storage room before being discovered. A small 4 meter by 4 meter decompression chamber separated the storage room from the adjoining hallway. SCP-303 occupied the decompression chamber for the duration of Dr. ██'s isolation in the storage room, disallowing entry from either direction and making it impossible for Dr. ██ to leave. Test Log 303-A, a team consisting of Dr. ██, Researcher ██, four security personnel and four D-class personnel, were assigned to be dispatched to any reported incident of SCP-303's materialization in order to immediately perform on-site testing. These logs take place at the door to room ██ in the first floor hallway. SCP-303 was reported to be within room ██, Test 303-1. One male D-class personnel, D-303-1, was ordered to open the door and threatened that he would be transferred to SCP-███'s duty for non-compliance. He refused, citing extreme fear. Test 303-2, one male D-class personnel, D-303-1, was ordered to open the door and threatened that he would be terminated on the spot for non-compliance. He refused, claiming that if he were to do so that SCP-303 would ██, he was terminated on the spot. Test 303-3, one female D-class personnel, D-303-2, that had witnessed the termination of D-303-1, was ordered to open the door and threatened that she would be terminated on the spot for non-compliance. She refused, claiming that if she opened the door that SCP-303 would ██, researcher ██ was visibly shaken by this claim. D-303-2 was not terminated. Test 303-4, one female D-class personnel, D-303-2, was ordered to open the door. One male D-class personnel, D-303-3, was given one combat knife by security personnel in order to ██ until D-303-2 opened the door. After two hours of ██, D-303-2 died from blood loss, D-303-2 made no attempt to open the door. Addendum ██, May 1, 2010 SCP-303 appears to have claimed the second floor storage room as its own. It has so far disallowed any personnel entry to the room since April 5, 2010. It leads periodically to a choir foundation property, which is then moved to the second floor storage room. Today, the following list describes all non-classified items taken by SCP-303. One ██ cryotube, three sets of standard foundation surgical equipment, two D-class research cadavers, one gasoline-powered generator, a variety of chemicals including large quantities of tryptophan, phenylalanine, ██ and tyrosine, among others. One container of powdered coffee creamer. In addition to this, a number of classified materials have been obtained by SCP-303. Staff are still attempting to determine what specific purposes SCP-303 may have for the materials. SCP-303 is now available at SCP-303, May 1, 2010, SCP-303, May 1, 2010 SCP-303 is now available at SCP-303, May 1, 2010, SCP-303, May 1, 2010
