Helium Helium is an important gas for diving because it enables deep diving. It is safer than hydrogen because it is a noble gas and has a weight of 0.17 kg/m3.As the previous section on oxygen and nitrogen showed, these gases pose a problem for the diver at depth. Oxygen because it becomes toxic at […]
