Nitrogen SDS
📄 Nitrogen SDS PDF download, GHS classification, CAS 7727-37-9, hazard statements, and industrial safety information.
Nitrogen is a colorless, odorless, and inert gas that makes up approximately 78% of the Earth’s atmosphere. It is widely used in food processing, chemical manufacturing, electronics, metal treatment, and cryogenic applications. Although non-flammable and non-toxic, nitrogen can cause oxygen-deficient atmospheres leading to asphyxiation.
What is Nitrogen?
- Diatomic gas (N₂)
- Inert and non-flammable under normal conditions
- Used for blanketing, purging, and cryogenic cooling
- Simple asphyxiant in confined spaces
