These gases are known to be chemically unstable. A chemically unstable sas is a flammable gas that is able to react exolosivelv even in the absence of air or oxveen. The investigation of accidents showed that the Chemical instability of flammable gases played an important role in the severity of accidents. Therefore, this hazardous property was included in the global harmonizatiön of the Classification of Chemicals. The Classification of chemically unstable flammable gases and mixtures is an amendment to Chapter 2.2 “Flammable gases” of the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS), because most chemically unstable gases are flammable as well. The proposal to add them to the GHS originated from the experts of an informal working group of the UN Sub-Committee of Expert on the GHS (UNSCEGHS) headed by BAM, Germany. The UNSCEGHS has decided to include it in the Fourth Revised Edition of the GHS. The respective method for determining whether a gas is chemically unstable or not, is included in the UN Manual of Tests and Criteria.

A1 - Holtappels, Kai T1 - Overview of hydrogen safety & remaining challenges in a green economy and energy transition N2 - In this talk, general aspects of the safety and acceptance of hydrogen technologies were presented. How can trust in new technologies be built when past accidents led to myths and fairy tales? The presentation does away with general prejudices and shows that handling hydrogen is neither more unsafe nor safer than handling other fuel gases. The basis for the safe handling of hydrogen is always a risk analysis.

The Hydrogen Clusters4Future bundle already existing expertise in the field of hydrogen technologies in and around Aachen with actors from Industry, Science and Society. All while considering the entire hydrogen life cycle – from production to storage and distribution to use. Safety is also an important issue and independant analysis on a national level is actually not possible in Germany. Other countries like the US and Canada established national safety alliances to offer support to companies and authorities. BAM, together with other independant institutes in Germany started to establish the National Alliance for Hydrogen Safety and presented this alliance to the community of the Hydrogen Clusters4Future.
