The reason is very simple, when a tanker truck carrying gasoline or oil moves, these substances often come into contact with the dry air inside the tank. On the other hand,
this air area rubs against the tank wall, so it is easy to become electrified.
Combining both of these conditions will easily cause a fire or explosion due to static electricity, which is a common phenomenon in life when an electrical imbalance occurs on the surface of a material.
Therefore, using a chain (with a high conductivity coefficient) will help solve the problem of static electricity by quickly converting these ‘static’ charges into electric current and transmitting it to the ground through a conductor.
chain to neutralize electricity, thereby avoiding causing a fire or explosion.
