The key dos and don'ts for safely handling gaseous and liquid hydrogen

This list can never be exhaustive. System and equipment engineers, as well as system operators, who deal with the generation and use of hydrogen must know the applicable regulations inside out and ensure compliance with them at all times. However, one thing has hopefully been made clear: Although hydrogen is a dangerous gas, these hazards can be overcome, just as the dangers of many other gases, such as propane, butane and natural gas, i.e. methane, have been mastered. It is equally important to ensure awareness of the properties and risks of cryogenic hydrogen. However, this also applies to liquid nitrogen and cold carbon dioxide. The unique safety-related properties of hydrogen are certainly no reason to overlook it as a key element in the energy revolution.
