Question

Vehicles carrying inflammable materials have chains hanging to ground.Give the reason

Answer 1

Answer:

The chains which are good conductors prevent the fire accident if any by conducting the heat to the earth.

Answer 2

Answer:

Vehicles carrying inflammable materials have chains hanging to ground 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 chains are hung so that any charge accumulated on the vehicle leaks to the earth.
