The criterion for quasi-static conditions for overpressure caused by internal air-gas mixture blast is substantiated in the article. In this process the blast pressure is considered as a function of time and does not depend on spatial coordinates. The article reveals calculations justifying the criterion for quasi-static conditions for the blast pressure. It is shown that the blast in large premises partially filled with a gas may not comply with quasi-static conditions, which leads to the wave behavior of the blast loads. The blast resistance analysis for the facility is given for the case of quasi-static conditions violation.
