This article is devoted to issues related to experimental studies of internal deflagration explosions or emergency explosions occurring inside buildings and premises. In internal emergency explosions, the main role in reducing the explosive pressure to a safe level is played by discharge openings blocked by safety structures (SS). As discharge openings, windows are often used, covered with glazed window blocks, or opened explosion venting structures (EVS). The article deals with processing experimental data obtained in the study of deflagration explosions occurring inside buildings and premises. The main features and difficulties that arise while analyzing experimental materials are described. The article considers the general methodology for processing experimental data to study deflagration explosions inside buildings and premises. Examples of processing materials from experiments performed in chambers equipped with a transparent edge allow high-speed filming of the explosive combustion process inside the chamber. The article presents a technique that allows, based on data processing on the overpressure in the explosion chamber, to obtain complete characteristics of the loads that occur in the experimental chamber during an internal deflagration explosion. The proposed technique makes it possible to abandon the transparent edge of the explosion chamber and obtain data on the explosion process based on the numerical processing of the excess pressure created in the explosion chamber. An example of processing a full-scale experiment to determine the effectiveness of a real explosion venting structure (EVS) is given.

The work addresses the alternative use of window sashes as an easily dumped structure (EDS) with window casement rotation to ensure gas release from the room and pressure venting. The paper focuses on the use of the option with one outside rotating casement as EDS while the other part of the window sash can be opened inside or be immobile. The work records equations for the movement of a swivelling safety structure and changes in pressure in a dimensionless form with identified dimensionless complexes, which equivalence ensures the likeness of aperture opening. The study is limited to the idle run period. It was demonstrated that with small room volumes, the idle run must be taken into account and its impact on a pressure growth must be reduced. The work shows ways to reduce the idle run time.
