Eye contact : Contact with rapidly expanding gas may cause burns or frostbite. Inhalation : No known significant effects or critical hazards. Skin contact : Contact with rapidly expanding gas may cause burns or frostbite. Frostbite : Try to warm up the frozen tissues and seek medical attention.
Gaseous helium is used as a coolant during the draw-ing of optical fibers, as a carrier gas for chromatography, and as a leak detection gas in a variety of industries. Being both lighter than air and nonflammable, helium is used to inflate balloons and airships.
Gaseous helium is used as an inert shielding gas in metal arc and laser welding. Being both lighter than air and nonflammable, helium is used to inflate balloons and airships. Helium can provide a protective atmosphere in the production of reactive metals, such as titanium and zirconium.
16 Μαρ 2024 · Excerpt from ERG Guide 120 [Gases - Inert (Including Refrigerated Liquids)]: Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground.
Most terrestrial helium present today is created by the natural radioactive decay of heavy radioactive elements (thorium and uranium, although there are other examples), as the alpha particles emitted by such decays consist of helium-4 nuclei.
Hazard Classification: Gases Under Pressure. Warning . Hazard Statements: Contains gas under pressure; may explode if heated. Precautionary Statements. Storage: Protect from sunlight. .
