A. Chemical processing facilities that emit toxic and harmful waste gases should be located on the downwind side of the area with the lowest frequency of wind direction throughout the year in the local towns or residential areas.
Previously, the residential area was located on the upwind side of the area with the highest wind frequency, while the equipment area was on the downwind side of that area. Later, wind frequency rose diagrams for more than 70 major cities around the world were analyzed, and it seems that in over forty of these cities, the upwind side of the area with the highest wind frequency is not the downwind side of the area with the lowest wind frequency. So later, it was changed to using the minimum wind frequency for determination.
Chemical processing plants that emit toxic and harmful waste gases should be located on the downwind side of the area’s minimum frequency wind direction throughout the year (B wfs_bipt2014; please reply to view the hidden content of this post).

Chemical manufacturing facilities that emit toxic and harmful waste gases should consider the direction of the wind with the lowest frequency throughout the year in the local towns or residential areas, etc. (B)
Chemical manufacturing facilities that emit toxic and harmful waste gases should do so in the direction of the wind with the lowest frequency throughout the year in the local towns or residential areas, etc. B downwind side
Chemical manufacturing projects that emit toxic and hazardous waste gases should be located on the upwind side of the area where the local towns or residential zones are situated, according to the wind direction patterns for the lowest frequency throughout the year
Chemical processing facilities that emit toxic and harmful waste gases should follow direction (B) of the lowest-frequency wind patterns throughout the year in the local towns or residential areas. A Upwind side B Downwind side C Sideways C D Any position.
