Liquid nitrogen depletes oxygen from the air. So, we had to run oxygen depletion monitors at key points to assure that oxygen levels remained safe and no one passed out or died of suffocation.
When oxygen levels drop below 19%, it’s time to leave the area. Levels remained around 21% throughout the contest.
Handling liquid nitrogen can be hazardous to your health. However, experts like our contestants do it with confidence and virtually no injuries. Injuries? If you don’t know what you’re doing, you can get frost bite on you skin or eye damage when the stuff comes shooting out of a valve on the tank.

Our 160 liter liquid nitrogen containers each weighed around 400 pounds full and had to be handled with great care. The contents were stored at 22 psi and whenever we moved the tanks or placed them in a warmer environment, they made a spectacular hissing sound as the tanks vented enough to keep pressure at the 22 psi level.
