About Helium

Helium is potentially the most versatile of the inert gases. However its extraction from natural gas is commercially viable in only a few locations, limiting its use to applications where there is no viable alternative.
Helium’s boiling point is very low, which makes it the only option for: Hydrogen purging – to purge and pressurise liquid hydrogen tanks and piping systems where other inert gases would freeze.

Uses of Helium

Helium is used in medical science as a medical gas in oxygen mixture to treat respiratory problems and as a refrigerant for MRI/NMR equipment.
Helium is the only safe gas to inflate balloons, from party balloons to hot air balloons
Helium can be used for quenching in heat treatment and leak detection in metal fabrication. Helium forms a critical components of aerospace and government/laboratory applications such as superconductors, leak detection, and high-pressure pumping systems.

Helium is an inert gas that causes oxygen depletion leading to asphyxiation and death. The danger is somewhat lessened by its low density, which makes it rise to upper levels where it is often able to escape.
Helium is capable of inflicting severe frostbite.
Helium has a low heat capacity which can lead to rapid pressure rises in vessels and the escape of very cold gas.
