What is the primary purpose of grounding cables in fuel systems?

The primary purpose of grounding cables in fuel systems is to minimize static electricity. In environments where flammable liquids are present, like fuel systems, the buildup of static electricity can create sparks that may ignite vapors and cause fires or explosions. Grounding cables provide a safe path for any accumulated static charge to dissipate safely into the ground, reducing the risk of ignition.

The grounding system is essential in preventing dangerous situations by ensuring that static electricity does not accumulate to hazardous levels. This practice is critical during the transfer of fuel, where movement and turbulence can lead to static charge generation. By minimizing the likelihood of static electricity accumulation, grounding cables play a vital role in maintaining safety standards in fuel handling and storage operations.
