Answer:
Vehicles carrying inflammable materials usually have metallic ropes touching the ground during the motion of the vehicle because the body of the vehicle in motion is charged due to air friction.
If the charge accumulation is large, it can produce a spark and the inflammable material may catch fire.
To prevent this mis-happening metallic ropes are hung so that any charge accumulated on the vehicle leaks to the earth.
