..SCP-XXXX-J does around here anyway. [containment procedure]

I don't think that "anyway" is necessary, even in non-official documents.

…advised to tell SCP-XXXX-J to chill…

It doesn't feel right for me. maybe change with "to calm down"? But this is minor. change is not really needed.

….in there somewhere.

This part seems redundant to me.

…endanger your cardiovascular health.

why use "your"? can't it written in third person?

…and doesn't recognize a meme.

two "and" in a row triggered me. And the word meme has really different implication in SCP, it's maybe only me though.

…as a result of SCP-XXXX-J's shitty mood,

the word "shitty" doesn't feel necessary
