Item #: SCP-xxxx

Object Class: Keter

Special Containment Procedures: All TSA metal detectors are to be fitted with devices that are shown to be effective at detecting xxxx-1 instances, found xxxx-1 instances are to be detained as soon as possible. SCP-xxxx is to be monitored via a temporary research and observation station currently located 1000 feet from the parking lot of the abandoned factory housing SCP-xxxx, the factory housing SCP-xxxx is not to be approached unless testing is in progress, testing with non human persons is forbidden and all non d-class personnel are to remain at a minimum of 50 feet from the room at all times. any persons caught trespassing onto the property containing SCP-xxxx are to be interrogated, amnesticized and either detained, released, or terminated at the digression of the off site lead researcher.

Description: SCP-xxxx is a room, marked with striped lines, indicating the width, length, and height of the room to be 42 feet in each direction. Almost all human persons entering the room have demonstrated the following effects:
They are unable and unwilling to leave the room without outside influence.
They will stare at the wall, floor, or ceiling, as if trying to find something important.
They are not resistant to being retrieved, and upon leaving the room, have shown signs of confusion as to their behavior while inside SCP-xxxx.
SCP-xxxx has seemingly no effect on non human persons

Persons not displaying these effects by SCP-xxxx are hereafter referred to as SCP-xxxx-1 instances
SCP-xxxx-1 are outwardly indistinguishable from humans, they appear to possess the memories of the person they were made from.
SCP-xxxx-1 seemingly attempt to blend in with the population, however every known SCP-xxxx-1 instance that has come across an opportunity to cause harm to a large number of people so far has done so without displaying any self preservation instincts, often dying in the process.
these events can occur years after exposure to xxxx.

Incidents known to be caused by xxxx-1
2013 Truck driven through now abandoned factory containing xxxx
2015 Owner of █████████, the company which owned the factory, starts a fire in his office building, all fire alarms and fire exxtinguishers were non functional and many doors were locked
2019 site-xx's on site nuke is detonated

Current estimates from data collected from metal detectors show that the -1 population is increasing, research into other possible locations effected by xxxx are ongoing.

Addendum: autopsy of a SCP-xxxx-1 instance:
[DATA EXPUNGED]

Addendum 2 update:
After review of recovered footage from site-xx's black box, it has been determined the area of effect for the secondary property of SCP-xxxx exceeds the bounds of the room. Resources for research are to be increased.
