Classification of hazardous chemicals
Thread Content
According to the global hazardous chemicals classification standard GHS, how should oxygen products produced by air separation be classified?
Oxygen, nitrogen, and argon in air separation fall under the category of hazardous chemicals as listed in Category 2: Compressed gases and liquefied gases, Subcategory 2: Non-flammable gases: Oxygen (compressed, liquefied), Nitrogen (compressed, liquefied)…
Compressed or liquid oxygen and nitrogen are classified as hazardous chemicals. Oxygen has a very strong oxidizing property; in an environment with pure oxygen, other substances burn very easily. And nitrogen has an asphyxiating effect. Therefore, it should be handled with caution.
