Non-refillable helium cylinders - a cylinder of pressurised gas if the cylinder contains predominantly helium gas and is not able to be refilled and reused.

Non-refillable helium cylinders safety standard

Mandatory safety standard on non-refillable helium cylinders - The proposed mandatory standard will require non-refillable helium cylinders to contain a blend of oxygen (about 21%) and helium (79%), rather than just pure helium. A label (also required as part of the mandatory standard) will highlight the composition of the blend, and that inhalation may cause suffocation. The scope of the proposed standard is non-refillable helium cylinders only.
