The paper presents the process of training methods’ selection in systems dedicated to detection of chemical hazards. By examining most common training methods used in detection systems, authors indicates which of them
are the most relevant to hazardous chemical substance detection systems, assuming that basic efforts focus on the system as the whole (mainly on detection components) rather than the training module. Furthermore,
the indicated methods are characterized in detail and combined with overall utility and economic analysis related to the dimension of the resources involved in the work on the entire project (by the example of
the EU-SENSE project). In order to study the training methods and the factors influencing their choice, two research methods were used: (1) in-depth analysis of the literature on the subject of training tools in the
field of crisis management and IT solutions, and (2) the case study of the EU-SENSE project (its training module).
