Typically, hydrogen is safely stored as a purified gas or liquid. Although hydrogen is a fuel, it needs an ignition source and the presence of an oxidizer, such as pure oxygen or ambient air, to combust.

In this test demonstration, a cylinder was filled with a dangerous combustible mixture of hydrogen and air. Once sufficient thermal or electrical energy is supplied, the mixture ignites, causing rapid combustion and the catastrophic failure of the cylinder.

Additional test demonstration videos like this one are exclusively available through hydrogen safety training courses at WHA International. You can also experience select live test demonstrations at our next in-person training event in Las Cruces, New Mexico.
