I have to disagree. Helium is not 100% safe. Try dropping a standard bottle of Helium where the valve breaks off, and the bottle becomes a missile hazard, likely killing anyone in its path.

If someone is working near the ceiling or in the top area of a building, and there's a Helium leak, the rising gas will displace Oxygen and can asphyxiate workers just as easily as any other gas that displaces Oxygen in an enclosed space.

Inert only means it isn't chemically reactive with other elements or materials. There are still dangers associated with the gas related to how it is stored or other characteristics of the gas.
