What is medical oxygen gas? What are the precautions for storage and use

Medical oxygen gas is a gas used for medical emergency and auxiliary treatment of some diseases, with a purity of ≥ 99.5% and meeting certain standards for acidity, carbon monoxide, carbon dioxide, and other gaseous oxides. Medical oxygen gas is mainly separated from the atmosphere through cryogenic separation, and undergoes multiple compression, cooling, and distillation processes to remove dust, impurities, carbon monoxide, carbon dioxide, and water vapor.



When storing and using medical oxygen gas, it is necessary to follow some important safety precautions. Firstly, due to the strong combustibility of medical oxygen gas, it is necessary to maintain a distance from flammable substances such as fats and organic powders to avoid combustion or explosion. Secondly, during the storage, handling, and use of oxygen gas cylinders, it is necessary to strictly follow safety operating procedures. For example, oxygen gas cylinders should be placed upright and anti tipping measures should be taken, and storage areas should be kept away from open flames and other heat sources. During transportation, it should be loaded and unloaded with care to avoid slipping, rolling and collision, and transportation vehicles contaminated with oil and grease should not be used. When in use, anti tipping measures should be taken, safety accessories should be provided, knocking or collision is strictly prohibited, and proximity to heat sources, power boxes, and wires should be avoided.



In addition, there is a clear difference between medical oxygen gas and industrial oxygen gas. Industrial oxygen gas only requires oxygen gas purity and may contain harmful gases such as carbon monoxide and methane that exceed the standard, as well as higher levels of moisture, bacteria, and dust. Therefore, it is strictly prohibited to use industrial oxygen gas for medical purposes.
