WebHelium gas is therefore used to test for leaks in high vacuum systems, fuel systems, and other containments. Helium breathing mixtures: Helium is used to prepare breathing gas mixtures for deep-water diving. Helium is inert and has a low viscosity under pressure, which allows easier breathing. Image by NOAA. WebA lifting gas or lighter-than-air gas is a gas that has a density lower than normal atmospheric gases and rises above them as a result. It is required for aerostats to create buoyancy, particularly in lighter-than-air aircraft, which include free balloons, moored balloons, and airships.Only certain lighter than air gases are suitable as lifting gases.
