Object Class: Euclid
Special Containment Procedures: No physical interaction with SCP-5212 is allowed any time. Gates must be guarded by teams assigned by the respected parties. Every personnel assigned must enter the site when signs of decay is all clear, and a period of Two months of quarantine is completed. Every interaction and the enter of site-233 must be approved by the respected parties. All personnel must enter the cell of SCP-5212 only on 12:00 midnight until 4:00 am to avoid the revival of SCP-5212 from it's slumber. All observed personnel with decay must be reported immediately. Any personnel reported with signs of decay must be quarantined inside site-233.
SCP-5212 is to be contained in a sealed cell, compromised of iron-lined stainless steels. The cell must be sealed within thirty layers of identical material. Teams are assigned to monitor the behavior of SCP-5212, and observe the cell of SCP-5212.
Any decay observed on the surface that has the depth of 4 inches must be reported immediately. Personnel must layer the surface again with layers of identical material until it reaches 1 meter. Layering must be done when SCP-5212 is inactive to avoid decay of all materials touched by SCP 5212.
Description: SCP-5212 appears to be a humanoid measuring at approximately 1.6 meters tall. It's skin shows no signs of hair, and completely devoid of pigmentation. I's eyes and mouth has an appearance of advanced decay. SCP-5212 is lacking the growth of limbs. Despite the lack of growth of limbs, SCP-5212 crawls using it's head and torso.
SCP-5212 causes a decaying effect on every material it touches. The effect travels through physical interaction, the effect shows "weakness" if the effect has traveled from more than one subject. The decay effect can be reversed by immediate disinfection of the material. However, this is not effective to human subjects.
Non-living subjects of SCP-5212 will experience normal decay. While human subjects will experience a n advanced decomposition. Every Living subject touched by SCP-5212 will appear to have no effects, but after 24-48 hours, they will start to experience an itchy red rash. After 72 hours, the rash will spread to the victim's body. After 96 hours, the rash will turn into decay. In this period, the victim may experience sepsis.
SCP-5212 shows aggression at day, and inactivity at night. If SCP-5212 is disturbed at day, it will show distress and immediately attack the subject. Documented speeds of SCP-5212 have varied from 20km/hour until 50km/hour. SCP-5212 will begin screaming and immediately launch at the subject. It will retreat immediately after it's attack. At night, SCP-5212 appeared to be in a really deep slumber, where every disturbance does not awake SCP-5212
Due to a high possibility of a mass chain reaction, it is recommended to observe signs of decay around site-233 and guard the entrance of site-233 to prevent the spread of the decay.
