Question
Why road tankers has a lengtĥ of chain hanging down to ground
Answers
GPT-4o mini
Road tankers often have a length of chain hanging down to the ground to help prevent static electricity buildup. When liquids, especially fuels or other flammable materials, are transported, there is a risk of static discharge due to the movement of the liquid and the tanker itself. As the tanker moves, the friction between the tires and the road, as well as the flow of the liquid, can create static electricity.
The hanging chain serves as a grounding mechanism. By creating a conductive path to the ground, it allows any accumulated static charge to dissipate safely into the Earth. This reduces the risk of sparks that could ignite flammable vapors or liquids during loading, unloading, or even transportation.
It's an important safety feature to help mitigate the risks associated with transporting hazardous materials.
