Chemical facts taught in firefighting training courses are often "isolated facts." In the book, these facts are integrated into an overall chemical-physical concept. Backgrounds are illuminated, and connections can be recognized. The overall understanding is facilitated, tactical measures for the operation become "logical".This book is a translation of the original German 1st edition Das Chemiewissen für die Feuerwehr by Torsten Schmiermund, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
