However, hydrogen gas has a few unique properties that require special consideration. For example, hydrogen can leak easily and ignite a relatively low temperature.
As with any fuel, safe handling depends on knowledge of its particular physical, chemical, and thermal properties and consideration of safe ways to accommodate those properties. Hydrogen, handled with this knowledge, is a safe fuel.
To ensure that hydrogen is handled responsibly, the International Organization for Standardization (ISO) is developing international safety standards. The Canadian Hydrogen Installation Code (CHIC) defines the requirements applicable to the installation of hydrogen equipment.
Companies that manufacture hydrogen and fuel cell products and build hydrogen stations use many features that continue to be validated through safety tests. Hydrogen has been safely produced, stored, transported, and used in large amounts in industry.
