Safety and security research

In the field of safety investigation, besides basic investigations into the chemical-physical behavior of propellants and explosives under different conditions, we carry out comprehensive and customer-specific risk evaluations and tests

The research group for technical safety is concerned with the safety risks of reactive and explosive substances and processes in systems, processing plants, and devices. The main tasks include safety-related designs, risk evaluations and their experimental validation on laboratory and real scale.
