Revision 12.1 [Site-11]. Electronic copy.


Submitted to Foundation Records Database. Archived File.

All field personnel and Foundation staff have been issued a clearance-specific copy of this manual as of 20/09/18. Do not copy or re-distribute.



The purpose of this documentation is to demonstrate the

Refer to this manual as your most reliable source. Lockdown procedures must be fast in order to achieve effectiveness, utilising speed as an advantage over the adversary threat. Misunderstanding basic regulations can endanger everyone you work with. Due to this, site administration requires all personnel to be familiar with this manual.


Unless directed otherwise, staff are reminded that the content of this manual is strictly classified, and remains site-specific in context. Distribution across sites is a Type-3a offence. Exchange/viewing of copies provided to separate personnel is also prohibited.

Staff suspecting a breach of this regulation are to contact administration immediately.



Over the years we have come to accept that an entirely secure facility, equally protected from both internal and external forces, is an impossible equilibrium to correctly achieve. This is why lockdowns are an integrated part of our Foundation system. Entering a mindset in which a goal of absolute control exists is a futile effort. It is important to consider that there is always more that can turn out wrong than right. Not relying on procedures such as these would be a complete denial of the wrong. The Foundation is built upon grounds of acceptance, not ignorance. Don't be ignorant.

- Dr. Sawer, Head of Site Safety and Containment Regulations Board.


A lockdown is defined as a varying emergency procedure in response to a containment breach or loss of security. Lockdowns are requested using an LRC (Lockdown Response Code), and ordered by the O4 communications group. Once evaluated, lockdowns are classified using Lockdown Degrees, which provides pre-created guidance on the appropriate response, such as AMTF (Armed Mobile Task Force) units and Automated Response Initiatives (ARIs), commissioned when appropriate to suppress the apparent threat.


Lockdowns first became official standard regulations following the 1931/03/12 containment breach, and multiple on-site accidents resulting in the severe loss of Foundation personnel, material, and vital assets. Since then, the Foundation has made substantial efforts to re-integrate a more secure, reliable and dependable methods of repressing internal instability among sites. Some of the first MTFs (Mobile Task Forces), such as Epsilon-11, were commissioned to advance against the increasing number of contained anomalous objects across the Foundation.

For a number of years, over the period known as the "deep waters", the Foundation was prone to regular breaches and loss of vital assets, due to influencing opposing factions, falling containment standards and disobedience of Foundation personnel, including the creation of the Chaos Insurgency in 1928, where the lowering ethics of the Foundation provoked a unit to go A.W.O.L and re-form as an extremely hostile splinter-group. The response to containment breaches was eventually re-considered and altered by the O5 council in 1935.

Following the containment of multiple Keter-class anomalies in the 1980s, containment breach severity and frequency increased dramatically throughout certain Foundation facilities. New Armed Mobile Task Forces (AMTFs), such as Nu-7 and Eta-5, were founded with the goal of assisting in re-containment and repression of these new threats. Contemporary material science had not developed to a point that would allow for the effective economical containment of these entities. However, as technology advanced, the threats posed by these anomalies and the period known as the "reptile scares" were eventually mitigated by the mid-1990s.

One of the most recent periods involving a Foundation-wide lowering in containment safety involved the infamous "two-naught-seven strikes" throughout 2015, in which eighteen sites were attacked by the autonomously fast, possessive and senselessly lethal entity known as subject two-naught-seven, presumed to have been created by the Chaos Insurgency (CI) in 2011 as an uncontained and un-coordinated biological weapon against the Foundation. The strikes were most effective because they were governed by a complete lack of knowledge regarding a spontaneous attack, the loss of vital security MTF teams, and multiple encounters with civilian populations - attempting to expose Foundation secrecy. Subject two-naught-seven was last observed on the 8th September 2017 in a disused metro station, after assaulting 5 separate MTF divisions and subsequently disappearing under an approaching train.



Lockdowns happen in a multitude of ways, and there are an even larger multitude of things you need to consider as a response. Categorising stops people panicking, and conveys a clear description much faster and more effective than a conversation.

After an illegal infraction has been proven against a Class-D asset, disciplinary action will be made. Highlighted below are the methods currently invoked to achieve such results.

NOTE: Disciplinary actions are listed as 'ACTIONS'.



D-Class assets reserve the right to be made aware before the application of amnestic agents or amnestic procedures upon them. It is illegal (Type-8 [ME] Offence) to administer amnestics or perform any attempt at psychological alteration on an asset without their prior knowledge. This includes if the subject is unconscious. Recognition of the statement is not required. Infractions on the part of staff can only occur if the administrator makes a clear attempt to mislead or inadequately explain the procedure to the asset.

Explanations of procedures must include if:

  • The subject is to lose personal or unrelated memories
  • The subject is to suffer character, personality or behavioural side effects
  • The subject is to suffer physical damage to the skull or surgery to the head
  • The subject is to suffer physical damage to the brain
  • The subject is to suffer lasting neurological (NOT: psychological) complications

Failure to describe the treatment if it includes one of the above constitutes as an offence against the ACTIONS 001-006, and is serviceable for a Type-8 [ME] Offence.


D-Class assets are no longer required to show concurrence or approval before administration. Administration can continue without consent or agreement.



All D-Class assets reserve the right to be made aware before the application of any amnestic agent upon them. It is illegal (Type-8 [ME] Offence) to administer amnestics to a D-Class asset without their knowledge. (NOTE: consent is not required.) This includes if the subject is unconscious. If the subject refuses to acknowledge the statement, administration can continue. Infractions occur only when the administrator makes a clear attempt to prevent the subject from being fully aware of the situation in the method their deliver their statement. For example, infractions have occurred against administrators who have delivered the statement verbally to deaf individuals, or attempted to mislead the subject, or attempted to deliver the statement incoherently.

In rare cases of incapable communication with the asset, amnestics my be administered through a MG-01 Break Law requiring the consent of the Ethics Committee before completion.

All D-Class assets reserve the right to be made aware before the application of any amnestic agent upon them. It is illegal (Type-8 [ME] Offence) to administer amnestics on a D-Class asset without their knowledge. This includes if the asset is unconscious. In rare cases, when the D-Class is incapable of communication in any form, amnestics may be used through a MG-01 Break Law, requiring the consent of the Ethics Committee before completion.

Further, D-Class assets reserve the right to keep their personal memories unless their removal is absolutely necessary. Removal of personal memories without cause is a Type-5 [ME] Offence and will require questioning by a local conduct review board (LCRB). If required, and justifiable, personal memories may be removed. Note: during surgery, action or procedure, amnestic administration is not questionable on spot, and will only be reviewed in the following days after the affects have taken place.


Specific Memory Suppression (SMS) Procedures often occur internally (on-site), and require careful use of Targeted-Retrograde Amnestics in cohesion with transcranial stimulation. SMR is referred to as 'memory hiding' by involved staff. On most occasions the surgery will be performed to lower specific memories from an asset (memories of neural-time < 60s) to a recall level of < 0.1. (considered forgotten).

Incomplete Memory Suppression (IMS) will result if the surgery was inadequate at recall lowering, and suppressed memories will usually surface at a recall level of 0.2, at which point the subject will still possess the ability to re-learn what they have forgotten. IMS is most frequently caused by incorrect stimulation of the subject or underdose of TR Amnestics, and is a serious (Type-3 [ME]) Offence and likely to result in a role demotion or discontinued employment.


Specific Engram Removal (SER) Procedures enact in similar function to a SMS Procedure, however attempt to prevent resurfacing of a memory through destruction of the original engram within the brain of which the memory is derived from. SER Procedures are applied to assets that are likely to become a cause information exposure through unreliable administration of SMS surgery or capture by hostile organisations intent on extracting the information from the asset using reverse-amnestics.

SER Procedures involve chemotherapy and electrotherapy used to destroy engrams and sections of the brain at a cellular level. As a result, assets who experience SER surgery are likely to experience mild-severe brain and memory damage, including possible early dementia, permanently.

Foreseeably, due to the risks of subject death (Type-2 [ME]), incorrect or unneeded personal memory destruction (Type-4 [ME]) and failed engram removal (Type-7 [ME]), SER procedures are rarely performed and only in required circumstances.


Administration of Class-G Amnestics as of now can be performed by any member of security or research personnel on a Class-D asset without consent from a higher authority, given that it is for a legitimate reason.

I make it clear, this is an exception to the rules. Gaslighting D-Class personnel is legal without consent from higher authorities, but use of any other amnestic agent other than Class-G without consent will hold you responsible for a Type-7 [IS] Offence.


Synopsis: suggests the escape of a sentient object below human intelligence capable of movement.

Special Guidance: N/A, follow orders from security.

Listed MTFs: MTF-Epsilon-11 ("Nine-Tailed-Fox")


Synopsis: suggests the escape of a sentient object equal or above human intelligence also capable of movement.

Special Guidance: identical evacuation plan to CODE: BLUE.

Listed MTFs: MTF-Epsilon-11 ("Nine-Tailed-Fox")


Synopsis: suggests any possible threat derived from a bio-hazardous1, infectious, or other contamination source2. These may include highly-infectious microorganisms3, biological weapons, or anomalous self-sustaining reactions4 capable of dramatically increasing in severity unless immediately countered. Not necessarily the escape of a single object, a CODE: GREEN may be often used in conjunction with another classification to signify a bio-hazardous threat.

Special Guidance: staff are to avoid contact with any sources of contamination or contaminated individuals above seeking evacuation. Do not leave the site. Staff should expect to be quarantined after the event.

Listed MTFs: Principal MTF deployed to all biohazards threats remains MTF-Beta-7 ("Maz Hatters"). In the case of an anomalous pandemic, MTF divisions will act rapidly in the containment and liquidation of areas affected by such anomalies, which may extend outside of the site if improperly contained. Incidents involving a catastrophic self-sustaining reaction are to be contained by possibly more teams so as to provide maximum efficiency to prevent further spread into an "unrecoverable" situation.


Synopsis: defines the parameters in which a Large-Scale Aggressor (LSA) such as SCP-2059, has escaped containment and currently poses a substantial threat to the site and Foundation secrecy.

Special Guidance: N/A, follow orders from security.

Listed MTFs: responses are usually of upper priority and almost all available battalion-strength AMTFs are expected to be allocated, such as MTF-Nu-7 ("Hammer Down") and MTF-Eta-5 ("Jaeger Bombers"). MTF-Gamma-5 ("Red Herrings") may also be dispatched to liquidate incidents involving possible public exposure/sightings. Expect a high-resource response. CODE: RED lockdowns are frequent and often well-planned, such is a recurring threat from SCP-682, so staff are to remain aware that security teams are prepared.


Synopsis: suggest the escape of a NTT (Non-Terminable Threat) such as SCP-096. A NNT is defined as a threat that, given the circumstances or present resources, is unable to be terminated by response teams during the incident, or are otherwise invulnerable to any form of attack.

Special Guidance: staff and security are advised to avoid confrontation with the NTT at all costs. Do not engage fire on the NTT unless it has been proven to slow/hinder the advance of the threat.

Listed MTFs: MTF-Epsilon-11 ("Nine-Tailed-Fox"), MTF-Sigma-23 ("Backup Required").


Synopsis: used to describe the assault of a highly-organised major/minor assimilation-force, one site-security are unable to combat.

Special Guidance: staff are advised to evacuate immediately. All SCP objects are to be put into lockdown, and doors/entrances to the site blocked. Data banks may be encrypted to prevent hostile acquisition of vital information. Do not attack hostile combatants unless absolutely necessary. Wait for AMTF battalions to arrive. Security are to protect staff and assets, not to repress the threat. Staff should be aware that defensive ARIs will be selected to combat human targets, and may be indiscriminately deployed during the holding of the site.

Listed MTFs: include all battalion-force AMTFs, such as MTF-Nu-7 ("Hammer Down").
