Editing SCP Foundation (section)

===Primary Class===
The initial labels given to any anomaly by the Foundation.

*Safe: This does not actually mean that the object is safe, but that the object is simple to contain and it is only dangerous if you mess with it. This includes stuff like people with weird but harmless powers, and objects that cause you to die a horrible death if you touch them but can't stop you from just locking them in a box. For the most part, these are as dangerous as a loaded gun: "safe" if you know what you're doing, and if you stick it in a secure locker, it'll be fine. This does also require that the Foundation can achieve 'you know what you're doing'; nothing is Safe-class when initially acquired, because they don't have a good enough understanding about the anomaly yet.

*Euclid: The object/entity is unpredictable and the Foundation has limited understanding of it. Special containment procedures (title drop) are required to keep it in line; the classic examples are the grand-daddy SCP-173, which has multiple video feeds watched by D-class (convicts stolen from death row) to keep it from moving, and the bigfoot SCP-096, which is stuck in an airtight steel cube with pressure sensors which is checked for holes or cracks, ''without'' looking at the wall you're checking, on a weekly basis. The consequence of a containment breach are also significant; at minimum, resecuring it will involve serious injury to Foundation personnel and some amnesticization of civilians, but mass deaths are often a possibility. If it's hard to contain but easy to keep out of sight of the public even if it breaks containment, it's ''probably'' Safe-class. Many Euclid entities, or pieces of Euclid entities, are sapient; any non-human-like intelligence is at least Euclid.

*Keter: The good shit. Also the bad shit. Almost all are an extremely dangerous tier entity/object. At best they're heavily guarded, protected by specially trained MTF's (Mobile Task Forces), and if they escaped containment would kill thousands and destroy the masquerade irretrievably. At worst, they would destroy the planet/galaxy/universe/multiverse, and they are being kept in a box which removes ''most'' of the avenues by which they could escape, only breaking loose once a year or so with a few hundred Foundation casualties re-containing it for the moment.
