Hydrogen storage systems based on reversible metal hydride technology are being introduced for consumer use. Due to the lack of appropriate regulations, codes and standards and experience for this emerging technology, there is the potential for inconsistency in their classification, labeling and treatment for shipping and installation. This document gives guidance to regulators, manufacturers and users of these systems to establish a consistent and uniform basis for the classification, labeling and treatment of such products.
