Liquid oxygen is a cryogenic liquid with a light blue hue. Liquid gases with a normal boiling point below -238 degrees Fahrenheit are known as cryogenic liquids.
Despite being mostly used as a gas, oxygen is frequently stored as a liquid. Liquid oxygen low temperature and the vapour it produces provide a major burn risk to human flesh. When exposed to oxygen, materials that typically burn in ambient air will burn more aggressively.
Uses :
The medical procedure of giving supplemental oxygen to a patient who cannot receive enough oxygen on their own is known as liquid oxygen treatment. Liquid oxygen treatment can be used to treat illnesses like pneumonia, lung disease, heart failure, cystic fibrosis, dysphasia, chronic obstructive pulmonary disease, and asthma.
The risks connected with liquid oxygen are as follows:
Exposure to extremely cold temperatures that can result in serious burns. The expansion of little amounts of liquid into huge volumes of gas in improperly vented equipment causes overpressurization. Oxygen addition to the environment around you. The potential for a combustion reaction if oxygen comes into touch with an incompatible substance. At specific pressures and temperatures, some common materials including asphalt, kerosene, fabric, wood, paint, tar, and dirt containing oil or grease can react severely with liquid oxygen.
