To minimize the risk of static electricity-related incidents in ISUZU tank trucks, several key operational and maintenance measures should be implemented. First, the tank's fluid level should be carefully controlled. Too little oil increases free space, leading to excessive sloshing and static electricity accumulation during transport, while overfilling can cause leaks from poorly sealed tank openings. A fill level of approximately 85% is generally recommended. Furthermore, drivers should maintain a moderate speed to keep the fluid relatively stable and avoid sudden braking.
Changing the type of oil being transported, such as switching from gasoline to diesel or kerosene, poses significant risks. Kerosene and diesel can absorb gasoline vapors, potentially changing the fuel mixture within the tank to within the explosive range, especially in cold weather. According to a study by the American Petroleum Institute, 440 out of 620 static electricity incidents involved product changes. When switching products, it is essential to completely drain residual oil, vent the tank to allow vapors to dissipate, and notify the previous product's loaders to adjust the transfer flow accordingly.
Keeping the tank free of water and impurities is also crucial. Water significantly increases the static charge in the fuel, raising the voltage by several orders of magnitude and potentially leading to sparkover. Impurities such as wood chips, rubber, or detached metal parts can act as capacitors, accumulating and storing static charge. The unpredictable movement of these materials can lead to proximity to tank walls or fixtures, creating a discharge gap. Testing has shown that sparkover can occur at potential differences as low as 1-2 kV, compared to the normal 28-30 kV, with the release of intense energy.
Valves, vents, and tank cap seals must be maintained in good condition to prevent leaks or spills that could ignite due to static sparks. Finally, before any loading or unloading, the tank truck and facility equipment must be properly connected using static wiring to equalize potential and prevent sparks.
