Dear Abhay,
Your using an iron rod is of no use, and not acceptable.
Having a meter of copper earthing rod of half inch dia, driven at least half a meter deep into the ground with undisturbed soil if well wetted will normally meet the requirement in Indian conditions to ensure protection against static electricity.
Bonding and earthing are different and to that effect you still have to adopt proper methods please.

Dear Sir
Thanks for your valuable reply... Could you please come with perfect answers to the quiries raised by you:
Here may I ask you few simple questions about the tanker earthing ?
Is its resistance ever measured ?
And if so what was the result?
What is the maximum resistance it can have for effectiveness ?
What depth we have to drive that rod to get that reading for effectiveness?
I have discussed the same with few electrical engineers but nobody was able to give a ready made answers and even after reffer given different reply's...
Hope to get positive reply from yourside.

Dear All,
We are going to buy Earthing kit for Unloading / loading tankers for our plant. when it is fixed, I will definitely paste photographs.
Keshav Sir,
U have given really a good answer for all queries.
Thanks and keep us guiding.

Dear Dipil,
Earth resistance measurement may vary from 0.5 to 20 ohms.
More than 20 ohms any where is not acceptable.
Mostly in Generating/Substation the earthing resistance will be too low and even possible to get a reading of 0.5 ohms.
Regarding earthing for tanker etc. for protection against ststic charge, it is already answered.
