Liquid Nitrogen is deadly dangerous as it will shut off the breathing
function of the human body when the Oxygen content falls below 19.5 %
and thereby causing suffocation.
This is not an unusual accident type in the Oil- & Gas- as well as in
the Shipping industry. For the sake of your safety I'm recommending the
use of an Industrial Safe Working Practice as a guideline before any
