Helium
He
Helium (He) is a colorless, odorless, non-flammable noble gas with an extremely low boiling point of -269°C. Its unique physical properties make it indispensable in a wide range of advanced industrial applications. Due to its rarity on Earth—existing mainly in natural gas and being non-renewable—helium is recognized as a strategic and scarce resource. As a leading global industrial gas company, Messer has established robust capabilities in helium sourcing, purification, and logistics. Leveraging long-term supply contracts in the United States and the Middle East, combined with our dedicated helium repackaging facility in Jiangsu, China, we provide our Chinese customers with a secure and consistent supply of high-purity helium to support precision applications across industries. Messer offers a comprehensive helium portfolio to meet varying customer needs, including high purity (5N) and ultra-high purity (6N) grades. We support a wide range of packaging and supply modes. With filling, storage, and distribution capacities across major cities in China, we can flexibly serve on-site demands and ensure high-quality gas management across every step of the value chain—from source to end use. Whether it’s uninterrupted supply, product quality assurance, or rapid response capabilities, Messer is committed to being a trusted partner for all your helium needs. Helium’s typical applications span across multiple high-tech sectors. In MRI systems, liquid helium is essential for cooling superconducting magnets and maintaining their cryogenic state. In the semiconductor and electronics industries, helium is widely used for chip cooling, plasma reactions, and gas-phase control. In aerospace and scientific fields, helium supports propulsion systems, pressurization, cryogenic testing, and leak detection. Beyond that, helium is used in laser and fiber optics equipment, where it helps protect fibers and lenses during manufacturing. In deep-sea breathing, in scientific cryogenic research, and in laboratories requiring ultra-low temperatures, helium remains an irreplaceable and foundational resource.

What Are Safety Hazards Associated When Working with Liquid or Gaseous Helium
Helium continues to boil and evaporate under ambient conditions, especially when it comes into contact with warm surfaces or objects. Boiling and splashing may become more intense. Make sure that proper protective equipment is worn when working around liquid Helium
Helium gas is colorless, odorless, non-toxic, and chemically inert, with no sensory warning properties. While helium is stable and non-irritating, it can displace oxygen in the air, potentially reducing oxygen levels below what is necessary to sustain life. Inhalation of helium can have a purely asphyxiating effect, leading to symptoms such as dizziness, nausea, and unconsciousness. Severe oxygen deficiency can cause death. Since the onset of symptoms is often rapid and without warning, individuals may lose consciousness and be unable to call for help. In extreme cases, loss of consciousness and death can occur within seconds.
As helium is lighter than air, it rises as it warms up and tends to accumulate near the ceiling in enclosed spaces. When the oxygen level in the air falls below 19.5%, no one, including rescue personnel, should enter the area unless equipped with self-contained breathing apparatus or supplied-air respiratory protection.
If you suspect unsafe helium buildup in a particular area, do not enter. Notify the appropriate safety personnel and keep other people away.
