I’m assuming you didn’t watch the video, but this particular helmet design has a completely open bottom. the only thing keeping the water beneath you out is the positive pressure from the air hose. Any excess air flows out the bottom.
it needs weights attached to it to keep it from floating (he attached just enough weight to keep it neutrally buoyant). If it sprung a leak, you would easily be able to remove the helmet either by lifting it up off you, or tilting forward or to the side and sliding it off. it is not strapped to the person at all.
Hm. Out of curiosity, do also believe that instructional videos of how to do house construction, electrical work, or brake repair on cars should not be freely available to prevent people from watching it and doing incorrectly and dangerously?
Your previous comment lead me to think that you disapprove of instructional videos of things that if replicated by someone who does it incorrectly it would become dangerous or life-threatening.

Yes, this one does. Someone copying it may make poor choices and change it in ways that are dangerous.

Also believe? I don’t think I ever said anything shouldn’t be freely available.

More speculation on how someone could mess up trying to copy it if they don’t consider safety
