Safety requirements: Hydrogen is a colorless, odorless, combustible gas. Forms an explosive mixture with air and oxygen. Hydrogen is physiologically inert; causes suffocation at high concentrations. When working in a hydrogen environment, it is necessary to use an insulating gas mask.
Transportation: in steel cylinders with a capacity of 40 and 50 dm3, as well as by pipeline Cylinders in special containers are transported by road.
Storage: cylinders filled with hydrogen are stored in special warehouses or in open areas under a canopy that protects the cylinders from atmospheric precipitation and direct sunlight.
Guaranteed shelf life of the product in cylinders is 3 years.
