When static electricity accumulates on the car body to a certain extent, sparks will be generated due to the discharge of personnel touching the car body or other objects touching the car body, thereby igniting or detonating flammable and explosive items on the car. Therefore, an iron chain must be installed under the car to release static electricity to the ground in time to eliminate hidden dangers.

2. The tank wall of the oil tanker is metal. During the operation of the car, the oil will rub against the car body, thereby accumulating static electricity. When static electricity accumulates to a certain extent, discharge phenomenon will occur, electric sparks will appear, and gasoline will easily explode. Therefore, there should be an iron chain on the car to guide the excess charge into the ground to prevent danger.

3. During the process of filling, transporting and unloading the oil tanker, due to the repeated contact and friction between the oil product and the oil tank wall, the pipes for unloading and loading oil, the electric charge accumulates and generates static electricity. When the charged body is due to the electric charge When the accumulation reaches a certain electrostatic potential, electrostatic discharge will occur, and there is an explosive mixture in the surrounding space. At this time, an explosion accident may occur. The tire is made of rubber, and the static electricity of the car body cannot be introduced into the ground, so Dragging it on the ground with an iron chain is intended to introduce static electricity into the ground and ensure safety! An iron chain is dragged at the tail of the oil tanker driving on the road. Its function is to introduce the static electricity generated during the operation into the ground, so as to prevent the static electricity generated during transportation from detonating the oil and prevent the occurrence of fire or explosion accidents.
