📄 Helium SDS PDF download, GHS classification, CAS 7440-59-7, hazard statements, and industrial safety information.
Helium is a colorless, odorless, inert noble gas commonly used in cryogenics, leak detection, semiconductor manufacturing, welding, and medical imaging systems. It is non-flammable and chemically stable, but high concentrations can displace oxygen and create a serious asphyxiation hazard in confined spaces.
What is Helium?
- Noble gas (He)
- Extremely low boiling point
- Non-flammable and inert
- Simple asphyxiant in enclosed environments
