metal balustrade /hand rail bonding

Newfutile

during an inspection and subsequent Consumer Unit change i have found the above to be bonded .

i have not checked this to see if its an extranous conductive part.

my thoughts are in a pen fault ,this could all become live  to some degree.

is the risk and results of this lower than no bonding at all?

    In my view the hand rail should be bonded. The hand rail or balustrade is probably already somewhat connected to earth via potentially damp building fabric, there are many opportunities for such  fortuitous contact with a structure that is electrically continuous over several floors.

    In the event of an open PEN there is the potential for a dangerous touch voltage between say a bonded metal pipe and the hand rail which is somewhat connected to true earth.
