Žižka, Jan. Thermal load of a firefighter during the liquidation of a fire in an enclosed space and the possibility of his/her protection, Dissertation. Ostrava: VŠB TU Ostrava, Faculty of Safety Engineering, 2021, 163 p.

The issue of fire elimination in an enclosed space is quite complex. Training facilities for flashover containers for firefighters (hereinafter referred to as FOK) enable experimental investigation of a number of aspects of fire dynamics in controllable conditions. For this reason, large-scale tests took place in FOK Zbiroh between 2011 and 2019. The individual measurements followed each other logically and in some cases were connected with laboratory research. In the initial stages, the research was focused on examining the parameters of the equipment, because it was necessary to demonstrate the safety and effectiveness of the training. It later focused on the response of protective equipment to heat. In the final part, the research focused on the study of the human factor and its influence on environmental parameters, inter alia in terms of influencing the function of equipment and armaments. The work describes the course of experiments and data obtained from a set of tests specify and concretize ideas about the laws and conditions prevailing in the environment of fire extinguishing in the interior. The main goal of the dissertation was to establish criteria, or a set of objective criteria, for assessing the hazards of fire in an enclosed space and the subsequent choice of effective measures to improve the protection and safety of firefighters during intervention in such conditions. The conclusions of the research can be applied in the form of proposals for the creation of safe tactical and training procedures for firefighters in the conditions of fire extinguishing in the interior and can be a suitable incentive for manufacturers of protective equipment.
