SCP-2604 prior to containment.
Item #: SCP-2604
Object Class: Safe
Special Containment Procedures: SCP-2604 is stored in containment cell 92 at Site 39.
Following Incident 2604-Alpha, all observation is to be conducted remotely. Under no circumstances are any Foundation personnel to come into direct visual contact with SCP-2604. Two armed guards are stationed to prevent exposure twenty-four hours a day. SCP-2604 is not to be moved from containment cell 92 under any circumstances. Any instances of SCP-2604-1 captured displaying late-stage symptoms are to be isolated immediately, and guarded by personnel with no prior exposure to SCP-2604.
Authorisation for testing rescinded as of Incident 2604-Alpha - O5-█
Description: SCP-2604 is a fence constructed from pine wood and iron nails. Interviews with witnesses and personnel that have come into contact with SCP-2604 have revealed that none of them are able to identify SCP-2604 as being a fence.
Direct visual contact with SCP-2604 causes a progressive cognitive dysfunction whereby affected subjects (hereafter referred to as SCP-2604-1) are incapable of recognising or responding to artificial barriers, markers, or pathways. The effect only progresses when subjects are in visual contact of SCP-2604; breaking this contact will arrest the progression. Amnestics have been shown to have little use, with test subjects reporting that they are unable to recall their observation of SCP-2604 but remain affected by the accompanying anomalous properties.
After three hours of exposure, SCP-2604-1 are incapable of recalling the purpose or usage of signs or barriers that do not physically prevent movement. After twelve hours, SCP-2604-1 are incapable of recognising that a barrier to movement exists as such, failing to identify any barrier, marking, or direction that would prevent movement, even to the detriment of safety.
In ██% of cases SCP-2604-1 will undergo a type-delta psychological restructuring (DPR) event following not less than 72 hours post exposure to SCP-2604. All cognitive dysfunction ceases, and SCP-2604-1 exhibit individuated responses to their exposure to SCP-2604. Common forms observed are:
- The ineffectiveness of containment as a principle (observed exclusively among Foundation personnel)
- Loss of personal inhibition
- Exhibition of markedly increased symptoms of pre-existing psychological disorders
- Significantly increased risk-taking or inability to manage risk
Individuals observed to have experienced a DPR event also exhibit the ability to hasten onset in SCP-2604-1, notably including instances with little or no prior exposure.
