Special Containment Procedures
SCP-XXXX is to be kept encased in a layer of concrete at least 5cm thick.
Description
The object is a small black detonator with a red button on top.
Experimentation has shown that upon pressing the button, the person who pressed it (in future will be referred to as 'The Subject') falls unconscious immediately. After 5-8 hours, the subject wakes up and acts as if SCP-XXXX doesn't exist. Precisely 24 hours after pressing the button, [REDACTED] marks form on the subject's body and they die instantaneously. Simultaneously, the five people who the subject knew best undergo the same symptoms as the subject. This process repeats until one of the people that is meant to undergo the symptoms is either dead or immune to one of the effects. Any person who exhibits the second symptom within 24 hours after experimenting with SCP-XXXX must be terminated immediately.
