I feel like the containment procedures are mostly spot on. It's suitably blocked off, and includes a nice hook in stressing the importance of the non-violent handling of trespassers.
The fact that the plants apparently grow at such an insanely dangerous rate leads me to believe that anything spilling blood will be effectively swiss cheezed by the overgrowth, and it would be incredibly dangerous to have humans operating in any fashion within the affected zone. Not sure exactly if it would happen like that though (someone more sciency…help).
Aside from that, I do like where you're going with the testing logs (the rare species of fish one in particular) though you could stand to lose this line:
After exclaiming [EXPLETIVE REDACTED] no less than three times
It comes off as a little cheesy, and broke immersion for me.
You could stand to put more thought into the last three logs. There's a decent enough buildup prior, but it falls into what I personally consider to be a cheap use of DATA EXPUNGED. Especially considering the fact that one test is expunged, with a reference to an addenda, which itself also has no information.
With some development, I feel like this could go far. Work on what you've got and try to get some more feedback before posting, though.
