The chain is there to prevent static electricity building-up and causing a spark that could cause an explosion. Any static electricity is led down the chain to earth.
petrol tankers usually have a chain to touch the ground so that the charges do not accumulate on the surface and cause an explosion. the cause of accumulation is due to friction, friction occurs when the charges are been attracted to the surface.
It disperses static electricity.
Gas tankers use a dangling metal chain to prevent static electricity build-up or discharge while filling the tank. This helps to reduce the risk of sparks igniting flammable gases or liquids.
That is a grounding chain. It is used to discharged any build up of static charged that may build up during the journey so that when the fuel is being loaded or offloaded the charge won't set the fuel alight. It should be noted that there are many other safe guards in place so this is not the only safe guard that is used.
No petrol - from petroleum, also known as gasoline in the USA, is an organic liquid and not a metal.
The metal that is commonly used in a petrol engine is mainly made of aluminum. Some are also made of cast iron.
The chain is supposed to get rid of any static electricity that builds up within the vehicle by directing it from the frame and tanks and into the ground or road. Preventing the buildup of static electricity will prevent the possibility of a spark occurring if somebody happens to touch the unit. We all know that gasoline is highly flammable, and its vapors are explosive, and the spark could provide an ignition source.
Petrol is a non-polar organic solvent, while sodium is a highly reactive metal that could react violently with the components of petrol, such as hydrocarbons. Also, sodium can potentially ignite in the presence of air or moisture, making it unsafe to store in a flammable environment like petrol.
There is a metal chain on a Honda car. This is also known as a timing belt.
Chain mail is linked rings of metal.
Metal.
yeah it is chain
