Intro. [RPG] We are the SCP Foundation; you are the SCP. Personnel must not enter the subject/SCP’s enclosure for any reason unless that subject/SCP is known to be passive or tame—that is, classified as Safe. Any SCP should be treated as a threat and must not be underestimated unless it has been proven not to be hazardous. D‑Class personnel are to be used in testing as either test subjects or for other necessary tasks, such as cleaning cells, feedings, or maintenance.
