4. Opening the external shell’s hatch, starting 35-minute 
countdown. Two employees enter the external shell, the 
third one stays outside and locks the hatch behind them. 
5. One of the incomers examines the inner surface of the 
external shell for any integrity violations; the second 
examines the outer surface of the inner shell. Regulated 
procedure time: 15 minutes. 

6. After finishing the procedure #5 the employees, 
considering the time left, make a decision on entering the 
inner shell. In case a negative decision is reached, see 
#10. In case of a positive decision: 

7. Opening the hatch of the inner shell. Starting the 15- 
minute countdown. One of the employees enters the 
inner shell; the other remains inside the external shell 


and locks the hatch from the outside. 

8. Examination of the inner surface by the incomer. It is 
essential to avoid any contact with the area within 3 
meters of the geometrical center during the examination. 
Regulated procedure time: 15 minutes. 

9. Regardless of the outcome of procedure #8, when 
finishing the 15-minute countdown, the incomer is to be 
in front of the hatch, being ready to leave. The hatch is to 
be opened by the employee outside exactly by the time 
the countdown is finished and only for 20 seconds, and 
closed and locked afterwards, regardless of 
circumstances. 

10. By the time the 35-minute countdown is finished, 
both employees are to stay near the external shell’s 
hatch. The hatch is to be opened by the employee 
outside exactly by the time the countdown finishes and 
only for 40 seconds, and closed and locked afterwards, 
regardless of circumstances. 

11. Leaving the containment volume. Debriefing and 
progress report to the operator. In case procedures were 
not carried out in full, another team is to be prepared for 
second examination. The second examination is to be 
conducted completely, regardless of progress of the 
previous team. 


Employees failing to leave the shells on time are 
considered KIA; no rescue missions are to be attempted 
under any circumstances. In case said employees are 
found during subsequent examinations, they are to be 
removed from the shells and remanded to medical staff 
immediately; taking off the suit and providing medical 
care is forbidden for any employees other than medical 
staff. 


Emergency protocols 


Transmission of information about the outside world into 
the shells in a form perceivable by the object (see 
description), even if not having observable 
consequences, is to be classified as a containment 


breach and aborted as soon as possible; termination of 
any employee is permitted if required to enact such. 
However, it should also be kept in mind that a deviation 
from the routine containment mode, as long as it remains 
stable, is preferable to frequent and sudden changes of 
the object’s surroundings; for this reason, containment 
restoration is to be conducted through decisive action, 
guaranteeing solid and sustainable results. 


In case of pressurization of the main containment 
volume, all turoomolecular pumps are to be shut off in 
order to prevent overload; all rotary vane pumps are to 
operate in overdrive mode to sustain a maximally 
achievable vacuum during recovery operations. If the air 
pressure inside of the containment volume exceeds 

1 mbar, all the operations are to be conducted in sound 
dampening mode. 


In case of visible integrity loss in any of the central 
shells, said shell is considered beyond repair. Instead, a 
new shell with a diameter 2m greater than the current 
outer shell is to be constructed around the central shells, 
if the outer shell is intact, or two successive shells if both 
current shells are damaged. After a new shell is put into 
operation, the old one is to be dismantled, removed and 
remelted. The current dimensions of the containment 
volume allow to conduct the procedure as many as five 
(5) times; hence, after fourth occurence of shell integrity 
loss and subsequent recontainment as described above, 
site personnel is to initiate work on containment volume 
expansion. 


In case of significant damage to both of the shells and 
thus an inevitable breach of containment volume, 
protocol 2470-Alpha is to be engaged. High Command 
must be notified of the situation immediately through a 
special hotline. Contained objects of little avail classified 
as “Safe” or “Euclid”, preferably extradimensional, info- 
or cognitohazardous, self-replicating upon destruction, or 
having a particularly complex structure (see: approved 


SCP list), are to be brought to the breach zone before 
any containment restoration procedures take place. 


This measure is supposed to mitigate the object's 
destructive influence by forcing it to spend a significant 
amount of time fully analyzing the complexity and 
inconsistencies of the aforementioned objects, while their 
unique properties should not allow SCP-2470 to make 
any substantial conclusions regarding the properties and 
laws of baseline reality. Any risks related to object 
interactions are considered justified. Permanent 
deployment of some of the objects from the approved 
SCP list inside the facilities of Area-141 is currently 
under review. 


In case of a BI (Before Invasion) class or TCF (Total 
Containment Failure) class scenarios, if any local factors 
directly compromise the safety of Area-141, or by the 
order of the O5 Council, protocol 2470-Beta must be 
engaged in order to neutralize SCP-2470. Four 
executors (2 main, 2 backup) are to be selected from the 
approved list and delivered to Area-141. The subjects 
must receive instruction and conduct test procedures on 
D-class personnel. The main and backup pairs 
afterwards stand on duty with a five-minute notice to start 
the procedure, until protocol 2470-Beta is cancelled by a 
direct order from O5 Council. 


At the order of High Command, or in case of sudden 
aggravation of the situation and loss of communication 
with the headquarters, the neutralization procedure is to 
be enacted under Area Command responsibility. After it 
is confirmed to be successful, the executors (both pairs) 
and all the D-class personnel located in Area-141 are to 
be terminated, any documentation relevant to SCP-2470 
is to be destroyed, and Area-141 is to be evacuated and 
destroyed via thermonuclear charge. 


Neutralization of the object, regardless of all the 
complexities of its containment, is the very last resort 
and is to be avoided until absolutely necessary. For this 


reason, subjects from the potential executors list are not 
to be present in Area-141 unless protocol 2470-Beta is 
engaged. 


Organizational aspects 


Due to the containment procedure complexity and 
unacceptable potential cost of error, a training complex 
has been established on Area 141 grounds for the 
purpose of general simulation of the containment volume 
and the containment area. All personnel involved with 
containment are to regularly practice under supervision 
of an authorized employee with level 3 clearance and 
take qualification tests at least monthly. Any non-routine 
works and procedures can only be carried out after 
training course simulations and rehearsals show a 100% 
success rate. Exceptions to this rule are permissible only 
on private order of Area Director in situations of extreme 
time pressure. 


Medical staff are to conduct physical examination of the 
working group prior to entering the containment volume 
and examine all Area-141 personnel monthly. Prior to 
deployment in Area-141, each member of the medical 
staff is to read, understand and sign the classified 
document 2470-x (attached) with a level 4 clearance 
employee as witness. 


Significant psychological tension caused by a large 
amount of important and demanding procedures 
associated with every entry into the containment volume 
(such as wearing and checking a full-body suit, passing 
through the four airlocks, calibrating numerous systems, 
working inside the shells under severe time pressure and 
others) necessitates extra attention to personnel’s 
mental health. Engineers assigned to the containment 
volume are to be given additional vacations. 


Any and all research of SCP-2470 is currently forbidden. 
Access to the archive of previously gained/retrieved 
information for purposes of analysis is allowed for 


employees with level 3 clearance or above by direct 
approval of at least two O5 members. 


As it is suspected that some members of the sect 
presumably responsible for the object's appearance or 
connected to it may be still alive and at large, Area-141 

is considered to be under aggressive threat. Although 
there is no reason to believe the aforementioned cultists 
to have any significant forces at their disposal, they 
possess information about the object that may potentially 
help them attract the interest of, and gain support from, 
other potentially dangerous radical organizations. 
Because of that, MTF - and - , apart from their main 
duties, are charged with monitoring the activity of any 
pro-apocalyptic groups and to actively instigate cultists to 
contact them by creating front radical organizations and 
sects. 


Description: SCP-2470 is a specific existential entity, or a 
perceptive element, which is objectively an initial manifestation of a 
ZK-class scenario. Due to insuperable obstacles related to its 
perception, the object's appearance, if it has any, remains unknown. 
Its current locus is determined indirectly, based on the area of effect 
it produces. 


Said effect is manifested through the instantaneous disappearance 
of any object or event perceived by SCP-2470 from objective reality. 
First and foremost this applies to the most proximate aspects, which 
are directly accessible to the object’s senses. Thereafter, as the 
object accumulates knowledge, gains abstract understanding of the 
nature of things, and makes generalizations, the effect extends to 
the phenomena themselves, their direct and later indirect 
consequences. 


For instance, during the initial recovery operation, it was noted that 
the sound of the agents' footsteps (said agents were obstructed 
from sight by smokescreens) was starting to drown out due to sonic 
oscillations having stopped. Soon afterwards, large volumes of the 
air itself started to spontaneously disappear, which caused 
hypobaric effects. This was followed by the disappearance of 
several agents’ legs, and finally the agents disappeared wholly and 


completely. In a similar fashion, at first several clots of the 
aforementioned smokescreen disappeared, but the effect soon 
spread to whole smoke clouds, followed by all active smoke 
grenades at the operation site. This culminated with disappearance 
of all smoke grenades of that specific type at the operation site, 
regardless of their being within range of the object's perception. 


Disappearance of soil caused a crater up to 200 meters deep to 
manifest at the location of the object's discovery (apparently, the 
object was somehow confused that every demanifested volume of 
soil brought more into view, and that slowed the process down; it did 
not manage to realize the Earth as a limited and finite entity). Due to 
constant disappearances of air, atmospheric pressure has dropped 
at the operation site and a steady high-current cyclone has formed. 


Since any generalizations of reasons behind any phenomena 
inevitably lead to using abstract concepts and eventually lead to 
logically reasoning the universe's existence per se, SCP-2470 is 
classified as a potential ZK-class hazard. 


According to the analysis of gathered data it was reliably established 
that the object possesses the following senses: 


* a perception of electromagnetic radiation in an extremely wide 
frequency range, including the visible spectrum, which is 
analogous to vision; 

¢ ahighly sensitive perception of mechanical stimuli, which is 
analogous to tactile sense and hearing; 

* a perception of [DATA EXPUNGED] 


The following senses are reasonably likely to be possessed by the 
object: 


* adirect, yet severely limited, telepathic perception; 
* a perception of certain quantum effects, particularly quantum 
superposition of states as a singular phenomenon. 


The latter hypothesis is related to the events that happened during 
[REDACTED], as well as damage and demanifestation of (at least) 
equipment sensors and human sensory organs during attempts to 

perceive the object directly, which is apparently related to the wave 


function collapse that inevitably accompanies an act of perception 
and is seemingly perceivable by SCP-2470. 


Moreover, this hypothesis combined with the conclusion regarding 
[DATA EXPUNGED] provides an explanation to how the object 
manages to avoid exposure to “Weif3schatten’s paradox”: 
apparently, the effect of quantum entanglement of the object in 
present time with itself in an immediate future, allows it to foresee 
the damaging effect of the memetic agent without even having a 
concept of its nature, and, based on that information, allows 
SCP-2470 to refuse to perceive it ("to close its eyes", metaphorically 
speaking). However, the fact that this modus operandi remains its 
only manner of existence for years in containment counts in favor 
of the paradox's adequacy and the proficiency of the developed 
neutralization procedure, which is based on a forceful inoculation of 
a destructive meme bypassing the object's senses.

According to another hypothesis, the idea of SCP-2470 
being a cognizing entity is not quite correct, as a ZK- 
class scenario can leave behind neither any knowledge 
of the current existence, nor any entities possessing 
such knowledge. Actually, the origin of the effect 
resulting in a ZK-class scenario lies not within the object, 
as we got used to thinking, but within the whole outer 
world. It is not the object that tears fragments away from 
reality, but the reality itself discharging these fragments 
and casting them into the most fitting place — into the 
unfillable unbeing that is SCP-2470 — as soon as they 
form a strong enough causal connection with it. 


Unbeing, as the true nature of the object, originates as a 
result of every successful attempt to perceive it. Thus, as 
unbeing is a priori singular, part of the object manifests 
on the information medium or inside the perceiver's 
mind, destroying it directly. Under this hypothesis, this 


explains the above-referenced effects on perception. 


From this perspective the cognizing nature of the object 
appears to be merely an illusion, caused by its dualistic 
position relative to the "forgetting" nature of the universe, 
though a virtual cogniton4 related to the object, created 
by this impact, appears to be indistinguishable from a 
real one (moreover, the concepts of "real" and "objective 
appear to be conventional and hardly applicable in the 
given context). This is what determines the object's 
inability to perceive “WeiBschatten’s paradox”, but in this 
case it appears to be an objective and natural limitation, 
not related to a willed refusal to perceive. From this point 
of view the effectiveness of the developed neutralization 
procedure seems very dubious. 


Recovery Log: The first report of the object's anomalous activity 
cameon . .20 atabout :00 from an airplane observer of FGU 
“Avialesookhrana’”>, who was conducting fire safety monitoring in the 
[REDACTED] area. The pilot reported a huge deforested area 
centered around a wide, deep cavity. Communication with the pilot 
ceased soon afterwards. The report was intercepted by undercover 
Foundation agents in the MES and a reconnaissance operation with 
mobile task forces was arranged.
