A metallic chain on a petrol supply tanker is designed to roll on the road to ensure it remains grounded, preventing the buildup of static electricity. As fuel is transferred, static charges can accumulate due to the movement of fuel within the tanker and friction with the air. By grounding the tanker, the chain helps dissipate any static charge safely, reducing the risk of sparks that could ignite flammable vapors. This safety measure is crucial in preventing fire hazards during fuel delivery.

Why is a metalic chain of a petrol supply tanker made to roll on the road?

A metallic chain on a petrol supply tanker is designed to roll on the road to ensure proper grounding and prevent the buildup of static electricity. As the tanker moves, friction can generate static charges, which pose a fire hazard when transporting flammable liquids like petrol. By rolling on the road, the chain helps dissipate these charges safely into the ground, reducing the risk of ignition during loading or unloading operations.

Why does a metallic chain be seen hanging from the rear side of a petrol supply tanker?

This used to be done with tanker trucks, but evidentally doesn"t work . the (Tiger"s tail) pun on Esso-later Exxon Tiger is supposed to ground or arrest sparks from lightning and act like a lightning arrestor in a fire-prevention role. it might work with ships, with a truck the possibility exists the chain might hang down, friction contact with the ground- and create thermal sparks-which could start fires rather than prevent them. it"s sort of an old superstition, I do not know of it ever preventing a fire or explosion! it isn"t done anymore with oil trucks, used to be rather pictureesque, even toy oil trucks had them scaled down.
