What factor influences the degree of static charge buildup during fueling?

The degree of static charge buildup during fueling is significantly influenced by the type of fuel being used. Different fuels have varying properties that affect their ability to generate static electricity. For instance, lighter fuels tend to produce more static charge due to their volatility and the way they evaporate, which can create more friction during the fueling process. Additionally, some fuels may contain additives that impact their electrical conductivity, further influencing static charge accumulation.

While factors like temperature and wind speed can affect the dissipation of static charge or the overall environment during fueling, they do not directly influence the buildup of static charge as much as the fuel type does. Certain fuels might be more prone to static buildup than others based on their molecular composition and characteristics. Therefore, understanding the specific fuel type is essential for managing static electricity risks during fueling operations.
