There is no means to contain SCP-001 known to the Foundation.
…
Aaaaand downvoted. If you OOC cannot think of a way that an object or event could be contained given resources with no canonical limit whatsoever, it's a failure on your part as an author to think and write creatively.
More importantly, it makes absolutely zero sense in character. The Foundation does not believe in "cannot be contained". If a researcher turned in a report on an SCP object that began "this cannot be contained" to his superior, that researcher would be fired.
So, fix that. I don't care if you make it "cannot be contained yet but here's how we're trying", or "containment has failed consistently, but MTF-fucknazis is currently working to implement and test a new containment strategy" or what, but put something down. We don't do uncontainable around here, because both in and out of character that is lazy.
