The assessment of the dangerous characteristics of pyrotechnic Composition and articles (for safe production)
- To minimize hazards during manufacturing and production processes of pyrotechnic compositions, semifinished and regular pyrotechnic articles, related properties of the pyrotechnic compositions must be determined and assessed with focus on those parameters that influence the exothermic reactions and explosion phenomena. Estimated impacts of these reactions as well as the sensitivities towards Initiation by thermal, mechanical or electrostatic stresses are relevant for this assessment.
Since the 50s of the last century so-called ‘Hazard Groups’(in German ‘Gefahrgruppen’) of pyrotechnic compositions were defined, to assess these properties which aim was to set appropriate safety measures for production purposes. This system of Hazard Groups is currently under review to determine if they are still relevant with the latest composition developments in this field and still represent the state of the art.
Several necessary changes and new approaches have already been identified.

This system of Hazard Groups is currently under review to determine if they are still relevant with the latest composition developments in this field and still represent the state of the art.
Several necessary changes and new approaches have already been identified. The new system will contain the following Hazard Groups, all with associated protection measures: 1.1 (and further sub-groups 1.1-1, 1.1-2 and 1.1-3), 1.2, 1.3 and 1.4. This structure is aligned to the international principles for the classification of such substances according to the TDG and GHS regulations. New or updated test and assessment criteria for these (sub-) groups are under development, and comprise of aspects such as sensitivity towards friction, impact, temperature and explosion effects.
This paper aims at giving an overview of this system of hazard Groups in Germany to optimize production safety including pyrotechnic compositions. An overview of this system is given along with example cases for testing and assessment, including a short differentiation of the energetic processes during the reactions.…
