Incident XXXX-2020A, ███████ Housing Complex

Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX instances can be repelled and ultimately dissolved via emission of sound waves in the frequency spectrum of 210kHz to 218.5kHz, hereafter referred to as a ”ban sound”. A provisionary containment ring of speakers emitting a constant ban sound is to be established around any new instances of SCP-XXXX.

Should the instance be too large or situated over impractical terrain, e. g. large bodies of water, the instance is to be cut down to a manageable size by emission of ban sounds. Once the instance has been contained, all civilian access to the affected area is to be halted. Cover stories are to be selected as appropriate.

Any and all civilians or foundation personnel caught within an SCP-XXXX instance are to be considered lost. Expeditions are to be conducted by means of unmanned vehicles. Once an SCP-XXXX instance has been cleared for termination, the established containment ring is to be slowly moved towards the center of the instance, effectively “crushing” it.

Description: SCP-XXXX is a field of as of yet unidentified nature, forming in and binding itself to a fog bank. While the water vapor making up the fog is entirely non-anomalous, from this point on the entire bank can be considered synonymous to the SCP-XXXX instance.

Should an SCP-XXXX instance remain uncontained, it will slowly expand at a rate of approximately 0.05% volume increase every hour. No instance has ever been recorded of reaching heights greater than 100 meters off the ground, but they are otherwise unaffected by local geography or weather patterns.

If any subject belonging to the family Hominidae comes into contact with SCP-XXXX-“infected” air, the subject will experience steadily increasing difficulty in breathing, eventually ending in asphyxiation. Removal from the SCP-XXXX-affected area drastically accelerates this process, resulting in the subjects death within a few minutes.

Additional symptoms may include paranoia, blurry and/or discolored vision, partial loss of hearing and general disorientation, increasing in intensity exponentially alongside the breathing difficulties.

During autopsies, no clear reason or cause for this effect has become evident, but the current belief is that some form of SCP-XXXX micro-organism binds to the subjects alveoli (lung bubbles), slowly breaking them down, possibly for nutrition. Exposure to an SCP-XXXX-free atmosphere presumably puts these organisms into a survival/repopulation state, greatly accelerating the breakdown.

While respiratory devices such as gas masks or full hazmat suits grant protection for a limited time, no effective methods of long-term protection other than ban sounds have been identified as of yet.
