The generation of electrostatic charges is significantly influenced by the environmental conditions surrounding the process. In hot, dry weather, the air tends to have lower humidity levels, which reduces the ability of moisture to dissipate static charges. This condition leads to a greater likelihood of static charge buildup, especially during the handling or draining of flammable liquids. The increased charges can be a concern in environments where flammable vapors are present, as they can lead to ignition sources.

Other environmental factors, such as cold wet weather or humid conditions, typically allow for moisture to conduct electricity, which helps dissipate static charges and reduce the risk of accumulation. Similarly, mild windy weather might not create the same conducive environment for build-up when compared to the lack of humidity in hot dry conditions. Thus, hot dry weather is most closely associated with an increased risk of electrostatic charge generation during such activities.
