UK/petrol installation

[techsing]

What is ment by,petol installation should have a earth electrode in stalled which is exclusive to the petrol station,where other earthing facilities are quite separate and EXTRANEOUS METALWORK MUST NOT BE SIMULTANEOUSLY ACCESSIBLE WITH METALWORK CONNECTED TO THE SUPPLIERS MAIN EARTH FACILITY.

Suggestion: Essentially, what is requested is an isolated grounding system for the gas station, which is a good idea if appropriate separation clearances are in effect to avoid any sparks, flash-overs, etc.
