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.
