Why should LPG supply stations be located upwind of the wind direction with the lowest frequency throughout the year

Let’s discuss it together. Why should LPG supply stations be located upwind of the wind direction with the lowest frequency throughout the year
To reduce the likelihood of pollution, in the event of a leak, minimize contamination of nearby residents
There are many posts on the forum about wind direction, with detailed explanations
On the upwind side of the wind direction with the lowest frequency throughout the year, so that in the event of a leak, the probability of flammable hydrocarbons being blown in is minimized.
In other words, it should be placed on the upwind side of the direction where wind is least likely to blow, with other equipment located on the downwind side. With this layout of the general plan, in the event of a leak from the LPG storage tanks and loading/unloading facilities, it is least likely that the hydrocarbon gases (resulting from the vaporization of LPG) will be carried to the production facilities located downwind of them (mainly electrical rooms, control rooms, duty rooms, and other areas and facilities where people are present or where electrical equipment is located).
4# getdy: If only the wind direction with the lowest frequency is considered, the downwind side is better than the upwind side； But on the other hand, the downwind side of the wind direction with the lowest frequency is not the same as the upwind side of that wind direction? Wouldn’t this mean that the probability of oil and gas leakage is higher on the downwind side than on the upwind side?
On the wind side at the lowest frequency, in the event of a leak or similar issue, the likelihood of harm occurring throughout the entire plant is minimal.
Basic safety knowledge – this is a requirement for the location selection of most chemical enterprises!
Facilities such as process units that may emit flammable gases, tank farms, loading/unloading areas, or plant-wide wastewater treatment plants should be located on the upwind side of areas with concentrated populations, as well as locations where open flames or sparks are present, in relation to the wind direction with the lowest frequency of occurrence throughout the year. It is stated in the design specifications and standards that facilities where flammable gases or toxic and harmful gases may be generated should be located on the upwind side of the wind direction with the lowest annual frequency of occurrence of people in that area
Can it be understood in this way: the minimum frequency refers to the lowest possible rate at which the blower operates. It is placed on the upwind side to prevent toxic gases from getting trapped, as that would be even more harmful.
