Helium is classified under the IMDG Code as a non-flammable, non-toxic gas that can cause asphyxiation due to oxygen displacement. It is transported in two forms, each with specific UN numbers and regulations:
UN1046: Helium, compressed – Classified under Class 2.2 (non-flammable and non-toxic gases). It is inert, lighter than air, and poses no fire or toxicity hazard but requires careful handling to prevent asphyxiation in confined spaces.
UN1963: Helium, refrigerated liquid – Also under Class 2.2, this form is cryogenic and requires special handling due to extreme cold and potential for rapid vaporization.
