When we think of oxygen, we think of living itself, since O₂ is what helps sustain life on this planet. It is the second-largest component of the atmosphere by volume, accounting for approximately 21 percent of all air. Without oxygen, we all will cease to exist. However, oxygen is used for more than just breathing and has numerous other applications in a wide range of industries. This is why cryogenic storage tank manufacturers create cryogenic oxygen storage tanks to store O2 in liquid form for a variety of industrial and medical purposes.
Cryogenic liquids are liquefied gases with normal boiling points lower than –150°C. And liquid oxygen is a cryogenic liquid with a boiling point of –183°C. Because the temperature difference between the product and the surrounding environment is significant-it is critical to. Keep liquid oxygen insulated from the surrounding heat. This is why special equipment like cryogenic oxygen storage tanks are needed for proper handling and storage.
Even though it is one of the main ingredients for creating life, it can also be life-threatening in its liquid form. Some of the major issues it can cause if not properly stored are listed below.
