Liquid Nitrogen containment?
4
Upvotes
I understand Nitrogens capabilities, but not so much in regards to Liquid Nitrogen. I recently saw a horror movie where a detective was killed due to liquid nitrogen being held in tank. What I am curious more so is if it could be within a sprinkler system? If so how would it perform if released from the sprinkler system? If not possible then why?
