Information to safely use this molecule
Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1- Metallic materials: ISO11114-1 (March 2012), Part 2 - Non-metallic materials: ISO11114-2 (April 2013), it must be used with extreme caution and engineering judgement. No raw data such as these can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is only used to identify possible materials for applications at high pressure and ambient temperature. Extensive investigation and testing under the specific conditions of use need to be carried out to validate a material selection for a given application.

Helium was discovered in 1868 by Jules Janssen. Its name comes from the Greek "ἥλιος" (helios) meaning "sun". Helium is abundant in the sun's atmosphere and is found at trace levels in Earth's atmosphere. However, it may also be found in fossil form in natural gas pockets in some oil fields, extracted by drilling deep into the subsoil. Helium is an extremely light gas and is therefore very volatile. It is colorless, odorless, non-flammable and completely inert.
