### Determination of Emergency Scenarios
Modelling the Consequences of Emergency Scenario 1-Leakage of the Entire Quantity of Fuel from the Tank during Filling  
In this section, the consequences of Emergency Scenario 1, focusing on the potential leakage of the entire quantity of fuel from the tank during the filling process, were explored. The following table (Table 6) provides a detailed modeling of the leakage using the software ALOHA version 5.4.7, considering different atmospheric stability conditions (D and F). The outcomes encompass various aspects, such as the toxic effects of the vapor cloud, flammability, potential explosion, and associated risks to both structures and individuals [44]. The effects of the BLEVE effect, i.e., the rolling of the heated tank and the immediate leak of the tank contents into the air with the subsequent fireball fire, are calculated only for information, because this effect is conditioned by a high pressure rise in the closed heated tank, which is not likely in tank chambers with pressure relief valves and \"tank breathing\" openings. \begin{table}

Table 6: Leakage of the entire quantity of gasoline from the tanker during filling modeled by ALOHA software. 3.1 Consequences of Emergency Scenario-Leakage of the Entire Quantity of Gasoline from a Tanker during Filling Explosive Effects of Gasoline  
If a sufficiently large plume of explosive substances is formed within the explosive limits when mixed with air, then the initiation of the plume results in a rapid transition of combustion to explosion by the formation of an airborne shock wave. In the case of escaped gasoline, the vapor cloud on surface evaporation from the plume will attain 60% at atmospheric stability type D at a distance of 75 m from the point of escape. In the event of an explosion initiated by an automotive gasoline vapor cloud, persons at a distance of 221 m from the point of leakage will be endangered by the impact of the airborne shock wave. Serious injuries will be sustained by persons within 52 m, and the exposure of persons to glass splinters has been determined to be 57 m. Buildings within 50 m of the blast site will be damaged by blast effects. (Table 6). Thermal Effects of Gasoline  
Fatal exposure of persons to thermal radiation in the model fire scenario is possible within 45 m of the flame. In the case of a fireball, its diameter would reach a maximum of 193 m and the burning time was set at 12 s. (Table 6). If gasoline leaks from a tanker during bottling, a puddle forms in the area around the dispensers, from which the gasoline evaporates.
