# Commission Regulation (EU) No 406/2010 of 26 April 2010 implementing Regulation (EC) No 79/2009 of the European Parliament and of the Council on type-approval of hydrogen-powered motor vehicles (Text with EEA relevance), Division 3.2.1


The pressure triggered pressure relief devices shall be fitted to the hydrogen container(s) in such a manner that they must discharge into an atmospheric outlet line that vents outside the vehicle. They shall not discharge at a heat source such as the exhaust. Additionally they shall discharge such that hydrogen cannot enter the inside of the vehicle and/or accumulate in an enclosed space. Additionally the first pressure relief device shall not discharge into a partially enclosed space. In case the secondary pressure relief device is a burst disc and is installed within the inner tank, an appropriate exhaust vent in the outer jacket is required.
