Liquid Nitrogen Signs

Liquid Nitrogen
Liquid nitrogen is one substance that is not to be trifled with. It possesses the capacity to freeze at a significantly lower temperature than water, making it an excellent refrigerant with many uses from culinary applications to cryogenics. However, it is this same characteristic that makes it very dangerous. Liquid nitrogen boils so quickly it generates tremendous pressure when transitioning from liquid to gas, making it dangerously explosive in sealed containers. Plus it’s lighter than air, which may lead to asphyxiation since evaporation increases the nitrogen concentration of the air – especially without adequate ventilation of the surrounding area.
  • Our Liquid Nitrogen Signs convey crucial safety instructions to users, allowing them to take appropriate preventive measures when handling or storing this hazardous liquid.
