Security Clearance Levels

STANDARD SECURITY CLEARANCE LEVELS

LEVEL 0: Standard operating personnel. Personnel at this level are not permitted any contact with an SCP object; breach of this protocol will result in termination of the personnel involved.
LEVEL 1: Standard security clearance level for staff involved in the maintenance of an SCP object. Level 1 clearance is usually appended with the SCP object the personnel have clearance for (e.g. 1/173).
LEVEL 2: Clearance level for staff involved in overseeing an SCP object. Appended with the SCP object the personnel have clearance for, separated by a dash for those with clearance for multiple SCP objects (e.g. 2/173-847-423).
LEVEL 3: All general security staff for Site-19 or any other site housing an SCP object are required to have this level of clearance and are permitted access to all non-Keter level SCP objects.
LEVEL 4: Command-level personnel; permitted access to all non-Keter level SCP objects.
LEVEL 5: Highest ranking Senior Staff; most personnel at this clearance level are Overseers. Certain members of Senior Staff have been given Level 5 clearance due to repeated need to work on Keter level SCP objects.
NOTE: This security clearance structure is independent of any other military security clearance structure.

NON-STANDARD SECURITY CLEARANCE LEVELS

D: Class D personnel are designated staff used to handle the Keter-level objects. Warning: Class D personnel are not permitted interaction with class D personnel assigned to a different object or SCP personnel. Class D personnel are recruited from prison inmates. Condemned persons are preferred; in times of duress, Protocol 12 can be authorized, allowing recruitment of innocents or persons incarcerated for lesser crimes. All Class D personnel are to be terminated at the first of the month, and a new staff must be ready to replace them. After placement in quarters, staff must only contact Class D personnel through intercom system. All Class D personnel are to be given a minimum of one (1) polygraph tests at 1800 on a daily basis. Failure to comply will result in termination. Failure to pass test will result in termination. In event of any abnormalities, termination of entire Class D personnel is advised, as well as any SCP personnel that have had basic interaction with them.
E: Temporarily affixed to the start of a security clearance (e.g. E1), this is used when a new SCP object has been discovered but is still in an unsecured or uncontrolled state. E-clearance personnel are tasked with bringing the SCP into effect and maintaining it. Once the SCP are in place and the object is secure, the E is removed and the personnel are given the appropriate number on the end of their clearance.
O5-x: Overseer-level clearance is given only to the directors of the SCP Foundation. The x indicates their number, ranging from 1 to 13 (e.g. O5-7). O5 personnel are permitted to access any and all data related to the SCP objects. However, due to the sensitive nature of their position, O5 personnel are not permitted to have any direct contact with an SCP object, nor may they enter any site housing an SCP object under any circumstances.

SCP Object Classes

Safe: Any SCP object classed as Safe is usually little more than a curiosity to the research teams, but is still anomalous enough to warrant containment in some form or another. Any SCP object classified as Safe can be interacted with by any member of staff, regardless of security clearance. This is also the only class of SCP object that anyone of O5-x clearance is permitted access to, though even then only under controlled circumstances.
Keep in mind that Safe class objects are not completely harmless: an automobile, or an AK-47, for instance, would be considered Safe, although it is capable of killing human beings. However, its functions are understood, and reliable safety measures can be taken to avoid harm.
Euclid: Euclid classification is generally applied to objects whose properties are not currently understood. Unlike Safe class objects, there are no reliable containment procedures on Euclid class objects: this may be because the object either does not obey known laws of nature and physics, or because its response to stimuli constantly changes. Objects classified as Euclid may be declined to Safe if a greater understanding of their properties is achieved.
Euclid class objects are not necessarily inherently dangerous, but they are unpredictable: for this reason, greater care should be taken around them. A wild animal, for instance may be considered Euclid, as it may have unpredictable responses to stimuli.
Keter: The strictest object class, Keter-class objects can only be handled by Class D personnel (see Security Clearance Levels) except in special circumstances. Keter objects are naturally inimical to life and pose great difficulties in keeping them controlled, hence the use of Class D personnel in their maintenance. Keter objects fall into one of two categories: those that are of immense strategic value once controlled, or those that have been deemed impossible to destroy due to the nature of the artifact. In either case, the artifact is to be kept until its use has been ascertained and replicated in a more controlled environment, or until a method of ensuring the objects' permanent destruction is determined.
Keter class objects are always inherently dangerous, despite the best containment procedures possible: the threat level may range from global armageddon to simply killing everything around it. A hand grenade with the pin removed may be considered Keter: a single mistake will cause casualties.
Neutralized: Any object that has since been destroyed, or in some way has no odd, extra-dimensional, or adverse effects. Objects classified under this class should have a note stating what class it was while it was an active SCP.
Decommissioned: Reserved for objects that are not only destroyed, but disavowed by the Foundation.

SCP-002

tem #: SCP-002


Object Class: Euclid

Special Containment Procedures: SCP-002 is to remain connected to a suitable power supply at all times, to keep it in what appears to be a recharging mode. In case of electrical outage, the emergency barrier between the object and the facility is to be closed and the immediate area evacuated. Once facility power is re-established, alternating bursts of X-ray and ultraviolet light must strobe the area until SCP-002 is re-affixed to the power supply and returned to recharging mode. Containment area is to be kept at negative air pressure at all times.
Teams including a minimum of two (2) members are required within twenty (20) meters of SCP-002 or its containment area. Personnel should maintain physical contact with one another at all times to confirm there is another person present as perception may be dulled, skewed, or influenced by proximity to the object.
No personnel below Level 2 are permitted within SCP-002. This requirement may be waived via written authorization from two (2) off-site O5-level administrators. Command staff issued such a waiver must be escorted by at least five (5) Level 3 Security personnel for the duration of their contact and must temporarily surrender their rank and security clearance. Following contact, command staff will be escorted at least five kilometers (5km) from SCP-002 to undergo a seventy two (72)-hour quarantine and psychological evaluation. If deemed fit for return to duty by psych staff, rank and security clearance may be restored when quarantine expires.

Description: Refer to the Mulhausen Report [cross-ref:document00.023.603] for details related to object's discovery. SCP-002 resembles a tumorous, fleshy growth with a volume of roughly sixty cubic metres (60 m³) or two thousand (2000) cubic feet. An iron valve hatch on one side leads to its interior, which appears to be a standard low-rent apartment of modest size. One wall of the room possesses a single window, though no such opening is visible from the exterior. The room contains furniture which, upon close examination, appears to be sculpted bone, woven hair, and various other biological substances produced by the human body. All matter tested thus far show independent or fragmented DNA sequences for each object in the room.

Reference: To date, subject has been responsible for the disappearances of seven personnel. It has also in its time at the facility further furnished itself with two lamps, a throw rug, a television, a radio, a beanbag chair, three books in an unknown language, four children's toys, and a small potted plant. Tests with a variety of lab animals including higher primates have failed to provoke a response in SCP-002. Cadavers as well fail to produce any effect. Whatever process the subject uses to convert organic matter into furnishings, is apparently only facilitated by the introduction of living humans.

SCP-003

Item #: SCP-003

Object Class: Euclid

Special Containment Procedure: Subject SCP-003 is to be maintained at a constant temperature of no less than 35°C and preferably kept above 100°C. In emergency situations, it is advised that the nearest personnel use their body heat to keep subject above the critical temperature. Additionally, all personnel who are required to use this method are to immediately report for sterilization.

Description: Found under conditions implied by remote viewing team SRV-04 Beta; refer to attached documents for detailed information. Subject appears to be composed of chitin, hair, and nails of unknown biology, arranged in a configuration similar to that of a computer motherboard. Subject was found upon the stone tablet on which it currently resides. Removal from this tablet is inadvisable except in case of emergency procedure above.
The runes on the tablet are not part of any known language, and flicker with pale tones. These seem to be benign effects of communication, and should be ignored by personnel.

Addendum 003-01: During power surge on date June 6, ████, the tablet runes flickered in red and yellow tones and an increase in radiation across the spectrum was measured in subject's containment area.

Addendum 003-02: We have managed to establish a link between subject and [DATA EXPUNGED] for analysis of functions. Subject is now considered sentient, and is to be kept a minimum of 1 km from [DATA EXPUNGED] and the resulting "by-product" at all times.

SCP-004

Item #: SCP-004

Object Class: Euclid

Special Containment Procedures: When handling items SCP-004-2 through SCP-004-13, proper procedure is vital. The items are not permitted off-site unless accompanied by two Level 4 security personnel. Under no circumstances should any other component of SCP-004 be taken through SCP-004-1. The effects of doing so are as yet unknown, and the current cost of experimentation makes further research impractical. Should any of the objects contained within SCP-004-1 break containment, or the facility be breached, the keys must be brought inside and the door closed prior to activation of Site 62’s on-site warhead. Unauthorized removal of keys from the testing area is grounds for immediate termination.
Level 1 clearance is required for basic access to SCP-004-1; Level 4 clearance is required for use of SCP-004-2 to -13.

Description: SCP-004 consists of an old wooden barn door (SCP-004-1) and a set of twelve (12) rusted steel keys (SCP-004-2 through SCP-004-13). The door itself is the entrance to an abandoned factory in [DATA EXPUNGED].

Chronological History

07/02/1949: A group of three juveniles trespassing on federal property near ██████████ find the door. According to their testimony, they found a set of rusted keys in an iron lockbox and determined what door the keys unlock. The juveniles are taken into custody after they contact Sheriff █████████████████ when one of their friends (SCP-004-CAS01) goes missing.

07/03/1949: Local authorities find the severed right hand of SCP-004-CAS01 eight kilometers from SCP-004-1. Other parts of SCP-004-CAS01's body are found scattered as far as 32 km from the factory. Under interrogation, the apprehended juveniles tell authorities that upon opening the door with one of the keys, SCP-004-CAS01 was torn into several pieces, each of which disappeared. At this point, the SCP Foundation takes over the investigation.

07/04/1949: SCP Agent █████ obtains the keys from the local authorities to begin testing. Tests show that SCP-004-2 through SCP-004-12 all fit into a single lock on the large barred door. 12 Class D personnel are assigned to test the effects of the door. Of the twelve (12) test subjects each trying a different key to enter the room, only two (2) survive. Opening the door with any key except SCP-004-7 or SCP-004-12 caused the test subjects to be torn apart in multiple directions; however, no dismembered parts were found until later. At the time of writing, only two (2) parts of each subject have been recovered (with the exception of the subject using SCP-004-█, whose pieces were scattered in close proximity). The others have, for all intents and purposes, vanished from existence.
Of the two surviving subjects, only one (having used SCP-004-7) returned unharmed. The other came back in a near-catatonic state, able only to remove himself from the room and then collapse on the floor, and had to be restrained to prevent him from gouging out his eyes (see Appendix A: Mental Health Effects of SCP-004). The subject using SCP-004-7 said that he had entered a large room, impossibly big for the size of the attached building. After his exit, SCP-004-1 was propped open and an armed squad of Level 3 personnel entered. The size of the room is impossible to measure and the door frame and the individuals in the room are the only part of the room that can be felt or illuminated.

07/16/1949: The juvenile suspects and Sheriff █████████████████ are terminated.

08/02/1949: █████████████████ is declared a hazardous area "due to unexploded ordnance" and fences erected in order to prevent civilian ingress. Tests to determine safety of exposure to environment behind SCP-004-1 begin.

12/01/1950: Space-time anomalies resulting from exposure to SCP-004 are confirmed. Testing is suspended until further notice.

07/03/19██: The unaccounted-for remains of SCP-004-CAS01 appear unexpectedly outside SCP-004-1. Despite being killed decades before, the remains of SCP-004-CAS01 are not decomposed in any manner and are still warm to the touch. Blood remains uncoagulated. The remains are remanded for testing.

07/04/19██: The unaccounted-for remains of one of the twelve (12) original test subjects appear in similar manner to those of SCP-004-CAS01. The remains have been designated SCP-004-CAS02. Records suggest that both SCP-004-CAS01 and CAS02 used SCP-004-██.

03/21/1999: With the massive proliferation of nuclear weapons and World War III only ██ years away, construction has begun on a site inside SCP-004-1. The site is to stock supplies for ███████ person-days.

04/21/1999: █████████████████ has ordered the site inside SCP-004-1 to be expanded to include emergency storage for all mobile SCP-███ specimens and a ██-petabyte database for the storage of all SCP data. The facility is now referred to as Site-62.

09/25/2000: Site-62 is operational. Labs and containment units are complete and can contain the most dangerous specimens. Backup of the SCP database has begun.

01/25/2001: Due to time anomalies (see “Space-Time Anomalies” below), all personnel working at Site-62 are now required to reside on-site permanently. Families of personnel are to be informed that loved ones perished in an industrial accident. Cloned bodies have been prepared for funeral.

07/14/2003: Massive power outage across Northeast United States and through Canada. Due to the initial failure of multiple SCP generators, Site-62 was without power for fifty-three (53) minutes. During those fifty-three (53) minutes, those on site were completely without any source of light. They reported "sensing" creatures and people, although no abnormal entities could be seen or felt. Selected facility personnel were allowed to read ████████████ (Appendix A) and said the creatures "sensed" were of humanoid size but otherwise similar to the massive green creature described.

Space-Time Anomalies

SCP-004 seems to propagate spatiotemporal anomalies. Personnel leaving the facility report losing time. Those who have been in the site for weeks insist that they had only been in the facility for several days, and records of work completed and supplies consumed support their claims. Other temporal anomalies involve SCP-004-2 through -13, especially the reappearance of SCP-004-CAS01 and SCP-004-CAS02 exactly ██ years after using SCP-004-██. ████████████████████ has been assigned to investigate all aspects of these time anomalies. Spatial anomalies include the impossibly large dimensions of the area opened by SCP-004-7. Similarly, the 2003 blackout incident suggests that there exists an alternate plane of existence within the same space that Site-62 occupies.

Further Notes

Testing on SCP-004 reveals that ten (10) of the keys open SCP-004-1 on a dimension where the laws of physics and topology are significantly different than those of our home dimension. Test subjects meeting these hostile conditions are torn apart, their body parts deposited in various locations, only three of which have been verified to be on Earth. Material deposited at two of these points appears immediately; material deposited at the third appears exactly ██ years into the future. The other seven locations are currently unknown.
Current testing focuses on two avenues of research. The first is finding ways to survive SCP-004’s hostile topologies. The second [DATA EXPUNGED] suggest that SCP-004-2 through -13 may open doors other than SCP-004-1.

Appendix A: Mental Health Effects of SCP-004-12

All Class D personnel using SCP-004-12 return in a catatonic state, unable to speak. Some may have enough energy left to try to claw out their eyes. Of the 16 subjects, only 4 have survived. Only one has regained speech, following long-term psychotherapy. He was able to tell the psychiatrist that he saw a massive green creature, so large that much of its body extended beyond his field of view. He reported innate fear and sudden recognition, “as if it were something buried deep in [his] primal fears,” and forced implantation of “incomprehensible” memories. Subject displays acute anterograde and retrograde amnesia.

Appendix B

Item #: SCP-004-14

Date of Discovery: 09/02/1950

Origin of Object: Object was discovered elsewhere in factory area, in the previously undiscovered manager's office.

Description: Object appears as a large (182 cm X 129 cm), unvarnished wooden box. The box may be unlocked by the "safe" key, SCP-004-7, as well as five of the "unsafe" keys (see Document SCP-004-1).
Upon unlocking SCP-004-14 with SCP-004-7, the box opens automatically on hinges. The volume of the space inside is precisely five times greater than the outer dimensions imply. Items placed within while the lid remains open do not affect the weight or any other properties of the box. When the lid is closed and locked, however, all items inside vanish irretrievably. Personnel locked inside the box are also irretrievable, although losing personnel in this fashion appears to affect significantly the dreams experienced by [DATA EXPUNGED].
