The book «Modeling of fire in the room» by B. In. The Loser is an in-depth and comprehensive study focusing on one of the most pressing and challenging topics in the field of fire safety. In today's world, where the risk of fires remains high, and the consequences can be catastrophic, this publication becomes an indispensable tool for professionals involved in the design, construction and operation of buildings. In his book, Nevdach offers readers a unique approach to modeling the processes that occur during a fire in confined spaces. It examines in detail the physical and chemical processes that occur in the premises, including the dynamics of fire propagation, heat flows and interaction with the environment. The author not only shares theoretical foundations, but also supports his conclusions with practical examples, which makes the material accessible and understandable for both professionals and students studying fire safety. This book will be of interest to a wide range of readers: from students of technical universities and graduate students, to experienced engineers and designers working in the field of construction and safety. It can also attract the attention of government agencies involved in monitoring compliance with fire safety standards, as well as researchers seeking to deepen their knowledge in this area. The themes raised in the book are diverse and multi-faceted. The loser discusses not only the technical aspects of the simulation, but also issues related to fire safety legislation, as well as modern approaches to risk assessment. He emphasizes the importance of proper design of buildings, taking into account possible scenarios of fire, which can significantly reduce the risks and minimize the consequences. The book also addresses the issues of education and training of specialists, which is an important aspect in the field of security .. The author’s style is distinguished by clarity and logical presentation . The loser skillfully combines a scientific approach with practical recommendations, which makes his book not only theoretically sound, but also practically useful. His experience and knowledge gained over the years in the field of fire safety allow him to share valuable insights and recommendations that can become the basis for further research and practical development.
