The paper simulates the damaging effect of a shock wave during an explosion of a liquefied propane-butane mixture. Calculations were performed using two methods. The first one was used to calculate the zones of destruction of buildings and destruction of people. For the second one, the values of the drift of the gas-air mixture cloud by the wind were determined. With this in mind, the possible danger zones were much wider. Thus, the zones of destruction of buildings and damage to people due to the spread of clouds along the earth’s surface increase by about five to six times. These facts must be taken into account when placing objects that use liquefied gases, as well as when transporting such gases. A probabilistic model was used to determine hazardous areas. As zones of possible destruction of buildings, such distances are conventionally accepted at which the probability of destruction is 90 %. Similarly, for people in dangerous areas, the probability of damage to the eardrums was 90 % or higher.

**Keywords**: shock wave, defeat, liquefied gas.
