### Toxic Effects of LPG  
LPG is slightly toxic. Narcotic effects are possible, in higher concentrations it causes asphyxiation. Inhalation of low concentrations of the gas with air has mild narcotic effects on the central nervous system leading to depression. Inhalation of high concentrations of gas with air may cause coma, which is preceded by a state similar to drunkenness and loss of muscular co-ordination. The toxic effects of the escaped vapor cloud will become apparent at atmospheric stability D at a distance of 322 m (355 m at atmospheric stability F) from the point of leakage. Modelling the Consequences of Accident Scenario 6-Leakage of the Entire Quantity of LPG from a Tanker during Filling  
In this section, we analyze the potential consequences of Accident Scenario 6, specifically focusing on the leakage of the entire quantity of LPG from a tanker during the filling process. The comprehensive modeling of this scenario, utilizing the ALOHA software, is presented in Table 8. Two different atmospheric stability conditions, D and F, are considered, providing insights into various aspects, including the toxic effects of the vapor cloud, flammability, potential explosion, and associated risks to structures and individuals. \begin{table}

Table 8: Leakage of the entire quantity of LPG from the storage tank during filling modeled by ALOHA software. 5.1 Consequences of Emergency Scenario-Leakage of the Entire Quantity of LPG from a Tanker during Filling Explosive Effects of LPG  
Upon initiation of the LPG vapor cloud in the case of atmospheric stability D, buildings at a distance of 118 m will be damaged by the pressure effects of the explosion, persons within a radius of 169 m will be at risk of serious injury, and glass splinters will be at risk of serious injury up to a distance of 360 m from the point of leakage (Table 8). Thermal Effects of LPG  
In the event of a jet fire effect, there will be a potentially fatal thermal radiation hazard to persons at 65 m, 2 nd degree burns at 93 m and serious injury at 144 m from the tanker. For atmospheric stability type F, the thermal hazard zones are smaller in this case (Figure 4).
